What is pro-progressive retinal atrophy?
Progressive retinal atrophy refers to a group of genetic disorders that cause degeneration and atrophy or wasting away of the retina – a layer of light-sensitive cells located at the back of the eye. It can lead to a continuous decline in the quality of vision and even result in blindness.
