New NICE glaucoma treatment guidelines

 New NICE glaucoma treatment guidelines

 

Glaucoma affects about 480 000 people in the UK. If left untreated it can lead to severe visual loss and blindness.

 

There are various treatments available to manage glaucoma and prevent visual loss. These treatments include a wide range of eye drops and surgical intervention. With the use of eye drops for the management of glaucoma it is of utmost importance that the drops be administered at the same time everyday to maintain a lower intra ocular pressure and prevent any pressure spike through the day.

 

The National Institute for Health and Care Excellence (NICE) has published updated guidelines for the treatment for newly diagnosed glaucoma cases. This includes the use of Selective Laser Therapy (SLT) for the management of Glaucoma and ocular hypertension. NICE guidelines recommend SLT as the first line of treatment for Open Angle Glaucoma.

 

SLT will make the management of glaucoma less complicated and more cost-effective. Patient compliance with eye drops will no longer be such a big factor in the management of the otherwise sight threatening disease.

 

There are only 27 UK Optometrist that are accredited to perform SLT for the treatment of Glaucoma. 26 of which qualified in December 2022. Andrew Matheson of Matheson Optometrists has been acredited in this line of treatment since 2019.

As yet accredited optometrists are only performing SLT in a hospital setting. Hopefully soon this procedure will be available in practice, which will make SLT available to many more people

At Matheson Optometrists we make use of state of the art equipment to ensure early diagnoses of glaucoma. It is advised that adult have a regular eye exam on a bi-annual basis and those with a family history of glaucoma be seen on an annual basis.

Dominic Cummings explained that he drove 30 miles with his wife and young child to ‘test his eyesight’ after travelling from London to Durham.

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.

The AOP has emphasised that those concerned about whether their vision is safe for driving should call their optometrist before making a car journey.

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.

“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.

It is estimated that 2900 road casualties are caused each year as a result of poor vision.

The AOP runs an annual road safety campaign, Don’t Swerve a Sight Test, designed to encourage all drivers to think about their vision and driving.

In the wake of the senior adviser’s explanation for getting behind the wheel during lockdown, people took to social media to share their views.

Optometrists, vision scientists and eye surgeons flocked to Twitter to point out that Mr Cummings would have been wiser to call an optometrist or attempt to read a clean number plate from a distance of 20 metres.

“If you suspect deterioration of sight, please don't drive to test how good it is,” a post from St Paul’s Eye Unit emphasised.

77 million Europeans with AMD by 2050.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

NEW Genius Platelet Rich Plasma PRP aids Corneal Repair

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.

Now we have a evolution of this treatment – the Genius in-house platelet-rich plasma (PRP) extraction and centrifugal preparation system. 

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. 

The Genius PRP system

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. 

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. 

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. I expect we will see much more about this recent development in the near future.

Rolando Toyos explained at the conference that this drip feed of growth factors helped facilitate proper regrowth of corneal nerves and reduction in inflammation, often still present after corneal healing seems complete.

Don’t swerve a sight test

The AOP Don’t swerve a sight test campaign, which first launched 14 November 2017, is designed to encourage all drivers to have regular sight tests.

With an estimated 2900 road casualties caused by poor vision every year, we’re reminding motorists that a sight test, every two years, can help them stay safe and reduce the number of accidents on UK roads.

Children don't know what's not normal. It's estimated more than 1 in 10 children have an undiagnosed visual problem which is affecting their learning and development. 

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. 

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. 

1 in 5 children in the UK are short-sighted

 (They can see things up close very well, but things in the distance are blurred; like the school board or teachers)

52% of parents believe every child has a full sight test at primary school, but this is not the case. 

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. 

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.

Children don't need to have symptoms to be seen by an optometrist. 

Screen Time

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. 

Depending on where they lie in the spectrum, coloured light is either long wavelegnths with less energey, or short with higher energy. 

Blue light?

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. 

Damage?

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. 

Sleep?

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. 

Nicotinamide hopes for damage in Glaucoma

Cardiff University has been granted funding, to research which dietary supplement of Nicotinamide, a form of Vitamin B3, can be used to help reduce and possibly prevent, retinal damage in Glaucoma.

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. 

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.

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).
