Dominic Cummings explained that he drove 30 miles with his wife and young child to ‘test his eyesight’ after travelling from London to Durham.<br />
<br style="box-sizing: border-box;" />
Mr Cummings revealed that he had concerns COVID-19 had affected his eyesight, so drove to the town of Barnard Castle as a test run ahead of his journey back to London.<br />
<br style="box-sizing: border-box;" />
The AOP has emphasised that those concerned about whether their vision is safe for driving should call their optometrist before making a car journey.<br />
<br style="box-sizing: border-box;" />
Dr Peter Hampson, clinical director for the AOP, said: “We are seeing a rise in the number of people who have a disregard for how important good vision is for driving ability, and it is impacting the safety of the individuals who use our roads.<br />
<br style="box-sizing: border-box;" />
“Sight loss can often be gradual, and can go unnoticed, so if you’re a driver and have concerns about your vision, while routine sight tests are currently suspended due to the coronavirus pandemic, most practices are open for essential and urgent eye care and will be able to offer advice over the phone,” he said.<br />
<br style="box-sizing: border-box;" />
It is estimated that 2900 road casualties are caused each year as a result of poor vision.<br />
<br style="box-sizing: border-box;" />
The AOP runs an annual road safety campaign, <em style="box-sizing: border-box;"><a href="https://www.aop.org.uk/our-voice/campaigns/drive-safely-dont-swerve-a-sight-test-campaign" style="box-sizing: border-box; color: #1080a6; text-decoration: none; word-break: break-word;">Don’t Swerve a Sight Test</a></em>, designed to encourage all drivers to think about their vision and driving.<br />

<span style="font-family: Arial, Helvetica, sans-serif;">Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in adults who are more than 50. A new study revealed that the condition might affect 77 million Europeans come 2050.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="box-sizing: border-box; caret-color: rgb(51, 51, 51); color: #333333; font-family: open-sans, sans-serif; font-size: 16px; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">A team of researchers unveiled new information about the prevalence of AMD in the coming decades in the study, which was published in the British Journal of Ophthalmology. The new data may help the health care system to plan on allocating resources for patients and careful planning in the next decades.</span></div>
<div style="box-sizing: border-box; caret-color: rgb(51, 51, 51); color: #333333; font-family: open-sans, sans-serif; font-size: 16px; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">The team came up with estimates through calculating information they pooled from 22 prevalence studies, which covered 55,323 people between the age of 60 and 81. The prevalence studies were those involving the existing disease, and the researchers also gathered information from four incidences (new cases) studies across Europe.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<div style="box-sizing: border-box; caret-color: rgb(0, 0, 0); color: black; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">The findings of the study unveiled that the number of existing cases is expected to boost by 15 percent. On the other hand, the researchers project that the number of new cases will increase by up to 75 percent in the next three decades.</span></div>
<div style="box-sizing: border-box; caret-color: rgb(0, 0, 0); color: black; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">The team estimates that about one in four older adults in Europe will develop AMD, spanning from one in ten cases in those who are below 65 years old, to nearly 27 percent of those who are more than 75 years old. The team also took into consideration the projections of those who will have advanced AMD, those who may experience irreversible blindness, and found that about 2.5 percent for all older ages combined.</span></div>
<div style="box-sizing: border-box; caret-color: rgb(0, 0, 0); color: black; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">Aside from the existing cases, the team also calculated for the new cases of advanced AMD. The team gathered information from 7,223 participants from four incidence studies. To calculate the annual rate of new cases of advanced AMD, they found that it was 1.4 new cases per 1,00 people more than 50 years old.</span></div>
<div style="box-sizing: border-box; caret-color: rgb(0, 0, 0); color: black; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">The annual new case of advanced AMD rate is 0.5 in 1,000 and 6.7 in 1,000 in those who are under their 70s, and those over 70s, respectively.</span></div>
<div style="box-sizing: border-box; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">Overall, the figures helped the researchers estimate that in total, about 77 million people in Europe will develop AMD in the next three decades, compared to 67 million in 2015.</span></div>
<div style="box-sizing: border-box; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">People who are more than 75 had the highest increase in case rates, increasing from 50 to 57.6 million, as much as 15 percent, in 2050. Those with advanced AMD is projected to also increase by as much as 20 percent, from 10 million to 12 million in 2050.</span></div>
<div style="box-sizing: border-box; line-height: 1.58em; margin-bottom: 25px;">
<span style="font-family: Arial, Helvetica, sans-serif;">Lastly, the researchers noted that the new cases of advanced AMD would soar from 400,000 per year to a staggering 700,000 in the next 30 years. Germany had the highest number of cases.</span></div>
<div style="box-sizing: border-box; line-height: 1.58em; margin-bottom: 25px;">
<span style="background-color: white;"><span style="font-family: Arial, Helvetica, sans-serif;">The researchers emphasized that most of the studies they pooled were from Western Europe; the results of the study can’t be applicable to Eastern Europe countries. However, they propose conducting further studies to strengthen the findings of the study, involving other countries or even other continents in the world.</span></span></div>

<span style="font-family: Arial;">Initially we had Autologous Serum eye drops. These were manufactured from plasma extracted from a patients own blood. These are bottled after extraction and enhance corneal healing because of all the regenerative growth factors found in our blood plasma.<o:p></o:p></span></div>

<span style="font-family: Arial;">The Genius system we saw at the recent 2019 Toyos Conference, is very slick, taking only 2 minutes to double spin/centrifuge the blood drawn. The whole process from drawing the blood to giving the patient 3 bottles of their own personalised eye drops takes 17 minutes. <o:p></o:p></span></div>

<span style="font-family: Arial;">A 30cc or 60cc sample of blood is usually taken from the patient’s non-dominant arm, typically from the Median Cubital Vein, the Median Cephalic Vein or the Cephalic Vein. These lie in the ante-cubital fossa which lies at the bend of the elbow at the front of the arm. Generally the Basillic Vein is avoided as it runs close to the Brachial Artery and the Ulna Nerve. The veins on the dorsal surface of the hand can be used, but require a higher level of expertise. <o:p></o:p></span></div>

<span style="font-family: Arial;">PRP contains 7.8x the concentration of growth factors etc compared to whole blood or plasma and is analogous to a drip feed of amniotic membrane every day. We will be watching this space carefully as I have several patients whose eyes are too dry and sensitive to wear an amniotic membrane and bandage contact lens, even for a week or two. This could the answer for them. <o:p></o:p></span></div>

<span style="font-family: Arial;">Most of the cross contamination of blood products issues do not apply as its autologous blood, the patient is only being given products made from their own blood.

It's estimated more than 1 in 10 children have an undiagnosed visual problem which is affecting their learning and development. </span><br />
<div style="font-family: Helvetica; font-size: 12px;">

<div style="font-family: Helvetica; font-size: 12px;">
A sight test can help your child achieve their best. All children under the age of 16 int he UK are eligible for NHS funded eye examinations. They have also provisioned for vouchers to put towards glasses or contact lenses for under 16's. </div>

<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
It is recommended taht children have a sight test with their local optometrist around the age of three. This allows any conditions which need monitoring or treating to be picked up early. After the first test, children should be seen every one to two years, depending on the optometrist's outcome. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
1 in 5 children in the UK are short-sighted</div>
<div style="font-family: Helvetica; font-size: 12px;">
<i>(They can see things up close very well, but things in the distance are blurred; like the school board or teachers)</i></div>
<div style="font-family: Helvetica; font-size: 12px;">
<i><br /></i></div>
<div style="font-family: Helvetica; font-size: 12px;">
52% of parents believe every child has a full sight test at primary school, but this is not the case. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
74% of Optometrist in the last year, have seen children with vision problems which could have been treated more high success, had they been detected earlier. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
1 in 50 children will develop a lazy eye, also known as amblyopia. This becomes more difficult to treat as the child becomes older and is irreversable once past the age of 8.</div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
Children don't need to have symptoms to be seen by an optometrist. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<b>Screen Time</b></div>
<div style="font-family: Helvetica; font-size: 12px;">
Sunlight or white light is made up of red, orange, yellow, gren and blue light rays. Combined together, this spectrum of coloured light creats white light. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
Depending on where they lie in the spectrum, coloured light is either long wavelegnths with less energey, or short with higher energy. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<i>Blue light?</i></div>
<div style="font-family: Helvetica; font-size: 12px;">
Blue light is high-energy visible light with much shorter wavelenghts, which is what is cause for concern. Blue light is naturally present in sunlight, but is also found in screens on our TVs, computers and phones. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<i>Damage?</i></div>
<div style="font-family: Helvetica; font-size: 12px;">
Currently, there is no scientific evidence that blue light causes damage to the eyes. However, there is evidence suggesting that working at short distances, for example on a mobile device or reading a book for long periods can cause increased eye strain. </div>
<div style="font-family: Helvetica; font-size: 12px;">
<br /></div>
<div style="font-family: Helvetica; font-size: 12px;">
<i>Sleep?</i></div>
<div style="font-family: Helvetica; font-size: 12px;">
Screen time close to bed time can cause poorer sleep quality, which means your chid's concentration levels throughout the next day are lower. This may be caused by the link between blue light and its suppression of melatonin the hormone which makes us feel sleepy. </div>

Fight for Sight has helped fund this important research which could help pave the way for new types of glaucoma treatments. Currently treatment is centred around reducing eye pressure and come at a great cost both financially and in time, to the patient and the health service. <o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; margin: 0cm 0cm 0.0001pt;">

<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; margin: 0cm 0cm 0.0001pt;">
As increased eye pressured is the main damaging driving force in glaucoma, the research will also test how effective Nicotinamide is in treating a wide range of eye pressure profiles.<o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; margin: 0cm 0cm 0.0001pt;">
There is currently a growing body of evidence which is shining a spotlight onto Nicotinamide and its protective role in preventing damage to retinal ganglion cells. (Retinal ganglion cell monitoring is now one of the latest ways to monitor and screen for glaucoma, it is also one of the earliest signs).</div>

The Cacicol drop belongs to the regenerating agent family (or RGTA). These agents are key in corneal matrix repair therapy (or matrix repair). Cacicol helps to trigger the regeneration of damaged tissues for enhanced healing. It makes it possible to delay or even avoid more invasive surgical procedures. ItCacicol is intended for the management of chronic corneal wound healing, such as in dry eye, with persistent epithelial defects (where the surface layer of cells the epithelium is damaged) and persistent corneal dystrophies with associated pain. Cacicol is a regulated healthcare product which requires a medical prescription, to ensure it is best course of treatment for each patient.Each box of contains 5 detachable and ready-to-use single-dose units and are preservative-free drops which are administered once or twice a week. CACICOL® acts as a scaffold. Its matrix structure permits the fixation and the protection of the components involved in the tissue regeneration process.<br />

<br style="font-family: Helvetica; font-size: 12px;" />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpy_aPW_Ub3B6twvn2JcbwtJRnOm5iZj4RnxcKx21ua2xhTHoYnXsiRxPzaCbG_-7SrDiwZ_VuXzmHrs8CxRO_naYfgvLuh098IqenLp6ZXPAgObCcEdd_nIk4zLUdSJyXE9mWyiQ282k/s1600/halloween-contact-lenses-9529.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="289" data-original-width="468" height="197" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpy_aPW_Ub3B6twvn2JcbwtJRnOm5iZj4RnxcKx21ua2xhTHoYnXsiRxPzaCbG_-7SrDiwZ_VuXzmHrs8CxRO_naYfgvLuh098IqenLp6ZXPAgObCcEdd_nIk4zLUdSJyXE9mWyiQ282k/s320/halloween-contact-lenses-9529.jpg" width="320" /></a></div>
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">To really complete an outfit, many people like to add special effect contact lenses to finish off their scary disguise. Be it coloured eyes, cat eyes or even white eyes there are so many options available, over the counter.</span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">Although these lenses can be bought in-store without a proper fitting, these seamlessly harmless lenses can be sight threatening. </span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">There are countless stories where these lenses have gone wrong, yet they still remain for sale both online and in store. A recent case in America say Gaye, a 20 year old party goer comes close to being blind.</span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">After wearing the lenses for a party, consulting an online video on how to insert them, Gaye struggled to remove them and fell asleep with them in situ. Later awaking to somewhat blurry vision and a strange sensation, she instilled eye drops hoping to diffuse the situation and went back to sleep. By midway through the next day, the sensation had become unbearable and Gaye feared she may be going blind. </span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">A trip in the ambulance to a&e, an ophthalmologist told Gaye she had scratches on the surface of her eyes, the term corneal abrasions. </span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">Dr Thomas Steinemann commented, “All contact lenses are medical devices and the lens has to fit the patient,” the professor of ophthalmology who treated Miss Gaye. “Even though you may not wear a correction (prescription), the lens still has to fit the outer surface of your eye, the cornea.”</span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">Though they may look legitimate, as fashion lenses are not regulated as they are from an optometrist they could themselves have germs or be defective with chips or tears. A study in America found 48% of these lenses were contaminated.</span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<span style="font-family: "helvetica"; font-size: 12px;">All contact lens fitting sessions come with dos and dont’s, to help ensure the safe use of the lenses. Things like avoiding contact with water, to prevent serious infection and even wearing the lenses inside out. </span><br />
<br style="font-family: Helvetica; font-size: 12px;" />
<br style="font-family: Helvetica; font-size: 12px;" />

The treatment has been approved as an option for treating RPE65-mediated inherited retinal dystrophies in people with vision loss caused by inherited retinal dystrophy from confirmed biallelic RPE65 mutations, who have sufficient viable retinal cells<br />
<br />
<br />
<br />
The drug is injected under the retina and carries a functioning RPE65 gene to act in place of the faulty one, and is recommended based on data from a Phase I clinical trial which found that the difference in mean change in binocular MLMT score between patients treated and the control group was 1.6.<br />

It's estimated that 86 people would be eligible for treatment with voretigene neparvovec in England<br />
The National Institute for Health and Care Excellence (NICE) has recommended Luxturna (voretigene neparvovec) for use in the NHS in England, making it the first available treatment for an inherited retinal dystrophy.<br />
<br />
Voretigene neparvovec is the first licensed gene therapy for vision loss caused by RPE65-meidated inherited retinal dystrophy.<br />
<br />
In the gene therapy, a healthy copy of the gene is injected directly into the eye so a working protein can be produced. Patients have to have some functioning retinal cells for it to work.<br />
Research has shown that, in the short term that the drug improves vision and prevents the condition from getting worse. The draft recommendations are now out for consideration by the company, healthcare professionals and patient groups. If there are no appeals, NICE expects to publish its final guidance next month. The treatment would then become available from January 2020. The voretigene neparvovec evaluation at NICE has taken 20 weeks instead of the average of 38 weeks within the Highly Specialised Technologies programme.<br />
<br />
This treatment is only for the treatment of Leber congenital amaurosis type 2 (LCA2) and severe early-onset RP caused by mutations in a specific gene called RPE65.<br />
Researchers are hopeful this could pave the way for similar treatments for dry age-related macular degeneration (AMD) to be made available on the NHS. Evidence from clinical trials shows that, in the short term, voretigene neparvovec improves vision and prevents the condition from getting worse. There is no long-term clinical evidence, but the committee considered it is biologically plausible that the treatment effect is likely to continue for decades.<br />
<br />
The list price of voretigene neparvovec is £613,410 per patient. This technology breached the Budget Impact Test, meaning it would have cost the NHS more than £20 million in one of the first three years after being introduced. However, the company has a commercial arrangement with NHS England making the treatment available to the NHS at a discount, the size of which is commercial in confidence.<br />
<br />
This gene therapy is similar to that used for the treatment of<span style="font-family: "arial" , "helvetica" , sans-serif;"> <span style="background-color: #f9fafa; color: black;"><a href="http://www.mathesonoptometristsblog.co.uk/2019/02/surgeons-perform-first-gene-therapy.html" target="_blank">Choroideremia</a></span></span><br />

<span style="background-color: white; color: #141414; font-family: "open sans" , sans-serif; font-size: 16px;"><br /></span>
<span style="background-color: white; color: #141414; font-family: "open sans" , sans-serif; font-size: 16px;">The Highway Code states that drivers must slow down or pull over if dazzled by bright sunlight and if you don't (and you're not wearing sunglasses to protect your eyes), you could be convicted of careless driving.</span><br />

If caught, you may receive an on-the-spot fine of £100 and up to three penalty points on your licence, or you could go to court where the fine can be increased up to £2,500 and nine points.</div>

However, as reported by <a data-link-tracking="InArticle|Link" href="https://www.plymouthherald.co.uk/news/uk-world-news/wearing-sunglasses-driving-could-land-1480302?_ga=2.166449534.1557824981.1524318992-1922960759.1520872421" style="color: #d90000; font-weight: bold; margin: 0px; padding: 0px; vertical-align: baseline;">The Plymouth Herald</a>, you can actually be breaking laws while driving with sunglasses on too.</div>

The reason for this is because sunglasses are divided into four categories based on the amount of light they filter out, with some being acceptable to wear while driving and others illegal.</div>
<div style="border: 0px; caret-color: rgb(20, 20, 20); color: #141414; font-family: "Open Sans", sans-serif; font-size: 16px; line-height: 1.8; margin-bottom: 23px; outline: 0px; padding: 0px; vertical-align: baseline;">
Most sunglasses are category two - meaning that they filter between 18 and 43 per cent of light and are suitable for driving.</div>

<span style="color: #141414;">If you have category four sunglasses, which let less than eight per cent of light through, you're </span><span style="color: black;">breaking the law.</span></div>

Everyone is aware of the dangers of both active and passive smoking and the recent smoking in public places regulations highlight this awareness. E-cigarettes are claimed by Public Health England(PHE) to be 95% less harmful than conventional cigarettes, largely because they do not subject the user or people nearby to tar and carbon monoxide. This is not endorsed by the National Institute of Clinical Excellence(NICE) as a smoking cessation device. Some respiratory specialists are concerned that Vaping “risks a further epidemic of lung disease for today’s children”.<o:p></o:p></div>

The nicotine is vaporised with a mix of polypropylene glycol and glycerine and often other flavourings. The vape material can cause adverse changes in the lining of the lungs which can lead to Chronic Obstructive Pulmonary Disease(COPD) and may be associated with heart disease (myocardial infarction). Vapes that contain nicotine salts rather than free based nicotine are less volatile and as such more of the nicotine reaches deeper into the lungs.<o:p></o:p></div>

As vaping has only been round for a relatively short time, we do not know all its adverse effects. We do know that the chemicals in the vapour such as formaldehyde are toxic to the ocular surface and can cause irritation and dry eye. This can apply to passive vaping as well as direct use.<o:p></o:p></div>

The nicotine itself can affect the eye especially in diabetics, by speeding up diabetic retinopathy and diabetic macular oedema. By reducing the retinal blood flow nicotine can contribute to the early development of Macular Degeneration (AMD). Eye Care Practitioners need to be alert for signs of these conditions in Vape users.<o:p></o:p></div>

A new trail compares drops and laser-based treatment could have a huge impact on how we manage the disease.<o:p></o:p></div>

A milestone study has opened up new possibilities for managing the disease. 80% of patients respond as well as they would to the eye drop PGA and if the laser treatment wears off over time it can be repeated. It takes 10 minutes in an outpatient setting, using a YAG laser and side effects are most uncommon.<o:p></o:p></div>

Research from Moorfields Eye Hospital and UCL Institute of Ophthalmology showed using SLT, selective laser trabeculoplasty on newly diagnosed patients was more successful and cost effective, than the current method of drops. SLT has become an established treatment for glaucoma but due to the lack in evidence and perception of the laser, has not yet been widely adopted.<o:p></o:p></div>

SLT is safe and more effective as a first line, with drops later as needed. 93% of patients met their pressure target at 3 years, with 72% not requiring any drops at all.<br />

SLT was first introduced in 1995 and become a recognised replacement for argon laser trabeculoplasty (ALT). Though both are effective and safe SLT is safer and more repeatable</span></div>

<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; line-height: 16.866666793823242px; margin: 0cm 0cm 10pt;">
Researches await the NHS to clinically endorse the laser as first-line which could be life-changing for glaucoma patients. Currently the eye drops work to lower pressure in the eye by increasing the fluid outflow and reducing the amount of aqueous the eye produces. Laser treatment becomes an option if the drops prove ineffective. <o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; line-height: 16.866666793823242px; margin: 0cm 0cm 10pt;">
According to the NHS, ‘you may need to try several types (of eye drops) before you find the one that works best for you. Sometimes you may need to use more than one type at a time.’ Consider the amount of time required both on the patients’ side and the prescribing medic, glaucoma can be a time consuming and costly disease. Requiring regular check-ups to monitor pressure and for those who are ineligible for free prescriptions, a financial burden too. <o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; line-height: 16.866666793823242px; margin: 0cm 0cm 10pt;">
Trabeculoplasty is used most often to treat open-angle glaucoma. A laser beam is used to place a small hole in the iris (the coloured part of the eye) which allows the aqueous to drain more freely within the eye so the iris doesn’t plug up the trabecular meshwork. <o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; line-height: 16.866666793823242px; margin: 0cm 0cm 10pt;">
This new form of treatment would reduce outpatient visits, if not eliminate them all together. Reducing the pressure on the hospital eye services and set to save the NHS up to £1.5m a year in direct treatment costs for newly diagnosed patients. <o:p></o:p></div>
<div class="MsoNormal" style="font-family: Calibri, sans-serif; font-size: 11pt; line-height: 16.866666793823242px; margin: 0cm 0cm 10pt;">

These results could fundamentally change how glaucoma is treated worldwide. <o:p></o:p></div>

There is huge publicity in a bid to attract people to have regular eye examinations and optic nerve checks, especially first degree relatives, FDR.<br />
<br />
FRDs are at 10 times the risk of developing glaucoma. If these relatives acted and had regular glaucoma checks, it's likely to save a great deal of sight. Glaucoma is a group of diseases, causing progressive damage to vision. What is surprising for most patients, is that it does so without any prior warning or symptoms until much later in the disease process. While treatment here is effective against further progress, so arresting the disease, there is no reverse to the damage done. Early diagnosis is key for preserving vision.<br />

Dry<u><b><a href="http://www.matheson-optometrists.com/macular_degeneration/macular_degeneration_info.html"> macula degeneration </a></b></u>has 2 subtypes, drusen based and atrophy based. In drusenoid macula degeneration there is a gradual build up of waste products in the retina, formed during the process of seeing. Just underneath the photo-receptors is the retinal pigment epithelium, the drusen deposits here disrupt the normal regular spacing of the photo-receptors and distort our central vision.<br />
<br />
There is a <u><b><a href="http://www.mathesonoptometristsblog.co.uk/2019/02/surgeons-perform-first-gene-therapy.html">gene therapy research</a></b></u> trial being undertaken in Oxford on dry AMD, which although is in the early stages is proving promising. The degenerating process and build up of waste product is normally slow and currently the only proven way to attempt to slow down progression is to take an antioxidant vitamin/mineral supplement, such as Healthy Eyes.<br />
<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAz7zC8YaVqxDqz27BJ1hxV0_nnKl7XFYm_KsjrSFkoND0_N7HuXDFdrhrFSkqpa_A09tAAiUS0IouOupDtOyV2qotLe6eWDsFosJPBozgiB0QR3xW82vHG6WDQABH1JjtU2hImv3fGtk/s1600/HE.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1600" data-original-width="773" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAz7zC8YaVqxDqz27BJ1hxV0_nnKl7XFYm_KsjrSFkoND0_N7HuXDFdrhrFSkqpa_A09tAAiUS0IouOupDtOyV2qotLe6eWDsFosJPBozgiB0QR3xW82vHG6WDQABH1JjtU2hImv3fGtk/s320/HE.JPG" width="154" /></a></div>
<br />
Healthy Eyes are a chewable supplement containing Lutein and Zeaxanthin which is perfect for those suffering or wishing to lessen their chances of developing age related Macula degeneration.<br />
<br />
The chews are formed from natural fruit pectin ( a gelling agent extracted from citrus fruits), giving it a pleasant and fruity taste. There are no artificial colourings or flavourings and are gelatin and gluten free. To suit most modern diets, they also contain no milk, wheat, eggs or nuts and have no artificial sweeteners.<br />
<br />
These waste products building up in the retina are now being picked up earlier than before, with<u><b><a href="http://www.matheson-optometrists.com/oct.html"> OCT</a></b></u> scanning and <b><u><a href="http://www.matheson-optometrists.com/autofluorescence_page_1.html">Autofluorescence Photography</a></u></b>. Matheson Optometrists are working with retinal camera developers in building a system for this. When Lipofusin (considered an aging or 'wear-and-tear' pigment) in the retina is illuminated with a specific wavelength of visible light, it fluoresces, or glows.<br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The first gene therapy procedure, aimed at stopping <a href="http://www.matheson-optometrists.com/macular_degeneration/macular_degeneration_info.html" target="_blank">age-related macula degeneration (AMD)</a> has just been completed by researchers.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Robert MacLaren FRCOphth a professor of ophthalmology at the University of Oxford undertook the operation at the John Radcliffe Hospital, also in Oxford.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The patient, Janet Osborne an 80-year-old woman from Oxford, has geographic atrophy (GA) which is associated with progressed dry AMD. It causes blurring in the central part of vision, for Janet in her left eye.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The procedure involves detaching the retina, injecting a virus-containing solution, beneath. Contained in the virus is the modified DNA sequence which infects the retinal pigment epithelium cells and corrects the genetic defect which causes AMD, reports Oxford University Hospital.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">"We're harnessing the power of the virus, a naturally occurring organism, to deliver the DNA into the patient's cells. When the virus opens up inside the retinal cell it releases the DNA of the gene we have cloned, and the cell starts making a protein that we think can modify the disease, correcting the imbalance of the inflammation caused by the complement system." MacLaren stated at the release.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">"It is an interesting application and approach to this very common cause of vision loss," Allen C. Ho, MD, the Director of the Retina Research Program at Wills Eye Hospital and OSN Retina/Vitreous Board Member noted.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The operation was the first phase of the 1/2 FOCUS trial, which is accessing the biological activity of the treatment, developed by Gyroscope Therapeutics.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">"What's unique about this particular clinical trial is that they are trying gene therapy surgically delivered to the subretinal space to try to modify the disease process," Ho said. While other clinical trials are testing injection therapies to treat dry AMD and geographic atrophy, there are no proven treatments currently.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Ho added, "Using gene therapy for this form of the disease to modify disease progression is interesting and exciting science, but not proven yet."</span><br />

Recent press has highlighted a batch of lenses used during cataract surgery, to be causing a decrease in vision. Typically the change is noticed at 36 months, where postoperative opacification has compromised the optical quality of the lens.</div>

<div style="background-color: white; color: #222222; font-family: Arial, Helvetica, sans-serif; font-size: small;">
Patients affected with reduced vision should contact one of our optometrist for further advice. The plastic lenses can become opaque after cataract surgery, in a process called PCO - posterior capsule opacification. It is a fairly common complication of cataract surgery and its treatment is simple and painless. The skin of the cataract which is left after surgery can sometimes thicken and degrade vision. A laser procedure is done in the outpatient clinic, which removes some of the thickened cloudy lens capsule. Treatment is quick and effective, returning vision to what is was like just after surgery. </div>

It is important to rule out macula oedema as the cause of reduced vision post surgery. Patients should undergo a thorough slit lamp examination and have an OCT scan. Which immediately shows any fluid or swelling in the macula, which is the part of the retina used for central vision. Macula oedema or fluid in the retina is a possible complication of surgery and should be checked an monitored. </div>

If you are experiencing any degradation in vision, come and speak to one of our optometrists who will complete a comprehensive post surgery check. OCT scans are now available at all of our practices. </div>

<br />
A pre-registration year with Matheson Optometrists?<br />
<br />
My name is Erica and I'm currently pre-reg here at Matheson Optometrists. I'm in the early stages of pre-reg but can not believe the amount of experience I have already gained.<br />
<br />
Training at a Matheson practice is a pre-reg like no other. The patient care is what brings optometry to life and is just how I imagined practice life to be while studying at University. Having a supervisor with IP (independent prescribing) has meant we care, treat and monitor a lot of pathology in house. Patients can be treated or prescribed for during clinic, with others referred to closely linked hospitals.<br />
<br />
There are a few practices within the group and we work between a mix of them all. Meaning no two days are ever the same. They are fast paced clinics, which often require you to think on your feet and be ready for new challenges. We manage RGP patients, BV problems, pathology and are also involved in glaucoma monitoring schemes.<br />
<br />
Within the first few months of testing, I've checked pressures on a patient with the Goldmann tonometer. Practiced my Gonioscopy skills with the other optometrists. Removed an ingrown eyelash and seen lots of interesting cases and OCT's first hand. The qualified Optometrists are always sharing more complicated cases for us to learn and discuss.<br />
<br />
If this sounds like the pre-registration experience you would love then please email your CV and a covering letter to Andrew at <b>amatheson@matoptom.com.</b> Tell us what you enjoy about Optometry and why you think you'd be a good fit. There is always something new to be learnt, so it's key you are looking to develop yourself as an optometrist and hone your skills.<br />

Contact lens giant, Johnson & Johnson recently announced their recycling scheme. In a similar fashion to Matheson Optometrist, they have public collection points for lenses. Patients simply collect their lenses in a box at home and drop them off in practice. The foil seal, plastic blister case and soft contact lenses can all be kept together! </div>
<div style="text-align: center;">
We are excited and proud to be pioneering the field with the environment in mind. You can drop off your used lenses at any of our practices. </div>
<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
The small pieces of plastic break up and pollute the environment, often when patients flush their lenses down the toilet. We wrote a blog post in more detail about this, which you can<i><u><a href="http://www.mathesonoptometristsblog.co.uk/2018/10/dont-flush-it-recycle-it.html"> read here. </a></u></i></div>

The mix up caused chemical burns to the cornea according to a report.<br />
<div>
<br /></div>
<div>
Healthcare services now look into using block capitals for written prescriptions. Dr Edington commented, "Prescribing errors are common, and medications with similar names/packaging increase risk."<br />
<br />
It was unusual that the prescribed erectile dysfunction cream, for a female had not been questioned. On discovery of the blunder, the patient was given antibiotics, lubricants and steroids. She showed good response to treatment and is recovering from the mild chemical injury.<br />

New treatment for macular degeneration?<br />
<br />
New research has been found not only to improve vision but also reduce the size and number of the debris built up at the back of the eye.<br />
<br />
This amazing new light therapy increases blood flow and stimulates the mitochondria in cells to regenerate. The process uses infra-red light to target tissues. Retinal cells are one of the most energy dependent cells in the body. The therapy light penetrates deep into the layers of the skin and increases energy production and signalling of these cells. The red light also reduces oxidative stress associated with smoking and can reduce inflammation.<br />
<br />
Researchers used a sample of damaged retina and treating with the red light they saw a huge improvement. A seven fold reduction in the release of VEGF, the growth factor which causes retinal damage. Left alone, VEGF stimulates growth of new, weak vessels which can leak and rupture. The light works by regulating signalling molecules, necessity for make energy and repair. The light therapy improves the cells ability to remove trapped waste built up in the retina and better repair from this damage.<br />

The National Eye Institute has received funding to support randomised trails in Canada, thanks to the results of these studies. The promising new treatment has many potential uses outside of optics too. Red light can be used to repair diabetic wounds, arthritis, as cancer radiation protection, in dentistry and even sports medicine.<br />

<u>Gene Therapy Success!</u><br />
A trial for choroideramia gene therapy has been reported. 14 patients at Oxford Eye Hospital received injections of a virus containing the missing gene, into the eye.<br />

<br />
Significant improvements to vision were found across the group of patients. 12 maintained or even gained vision, which remained for up to five years. Of the untreated eyes, only 35% sustained vision.<br />
<br />
<i>"I was going into the operating theatre and having my eye injected with a virus that was used to insert the correct DNA into my cells so that the missing protein was produced. After the operation, I had my month one test. When I was doing the usual eye chart test, I had a lightbulb moment. I realised that I was about to go on reading past a point I had not reached in a decade.</i><br />
<i><br /></i><i>I read the equivalent of four lines on the eye chart more than I could before. I was sitting there reading and I had tears just streaming down my face with this massive grin"</i> - Joe Pepper, a Surrey teacher on receiving gene therapy.<br />
<br />
This research will hopefully pave the way to future breakthroughs, for other eye diseases including macular degeneration.<br />

<br />
Choroideremia is a condition that causes progressive loss of vision. Mainly affecting males, the first symptom is usually night blindness. Patients often feel their vision is not as good in low lighting, often starting from early childhood.<br />
<br />
The visual problems are a result of loss of the cells that pick up light and also the choroid blood complex surrounding,this is also known as atrophy. As the condition progresses, visual field loss can follow, narrowing to leave tunnel vision. Fine detail or acuity can also be lost over time.Generally vision can decrease over time, but the severity each person experiences can vary.<br />
<span style="font-family: "times" , "times new roman" , serif;"><br /></span>
<u><span style="font-family: "times" , "times new roman" , serif;">Cause</span></u><br />
Choroideramia is caused by mutated genes, specifically the CHM gene. CHM gives instructions and attaches to other molecules called Rab proteins inside cells. A mutation causes a cascade of events which mean the Rab proteins can not reach or attach to the correct area (organelles inside the cells), cells then die off prematurely.<br />
<u><br /></u>
<u>Inheritance</u><br />
An X-linked recessive pattern. The X-chromosome, one of the two sex chromosomes, are found as pairs in females XX and XY in males. So males only require one copy of the mutated gene to cause the condition, while females need two mutated copies. Women with just one copy are called carriers, they generally will not have symptoms of choroideremia but may show small areas of cell loss during a thorough eye examination. Though these changes may affect vision, but later on in life.<br />

<u>Statistics</u><br />
It's estimated that choroideremia affects 1 in 50,000 to 100,000 people. It has been noted that they condition may go underdiagnosed because it shares similarities with many of eye disorders.<br />
Of all causes of blindness, choroideremia accounts for 4%.<br />
