A new study has claimed radiation treatment can successively be used in cases of wet age-related macular degeneration (wet AMD), which leads to blindness in older adults.
Some 21 international centres including King's College London and the Manchester Royal Eye Hospital contributed to the research, which found the radiation therapy could significantly lower patients' need for injections directly into their eyes.
Dr Tim Jackson, an NHS eye surgeon who led the UK arm of the trial, said around half of those who took part in the programme experienced improved vision as a result.
"These are good results, but we would always want a further long-term follow-up to establish the safety and effectiveness of the treatment," he added.
Earlier this month, the results of the HYDRUS I clinical trial showed glaucoma patients could benefit from the development of a tiny draining device for the eye.
