Blind man has sight partially restored after 40 years

A blind man has had his vision partially restored using optogenetic therapy and engineered goggles -- the first successful case of such therapy in humans.
Researchers treated a 58-year-old man who for 40 years had been suffering from retinitis pigmentosa -- a neurodegenerative eye disease where loss of photoreceptors can lead to complete blindness. Retinitis pigmentosa changes how the retina responds to light, making it hard to see, and people with the condition lose their vision slowly over time, according to the American Academy of Ophthalmology.More Related News
