What is retinis pigmentosa; what happens to the eyes?

Genetic disease: Retinitis pigmentosa is a genetic disease where certain layers of the retina slowly degenerate, causing loss of the photoreceptors and a gradual narrowing of the visual field. Eventually the person is left with narrow, tunnel-like visual fields. They don't usually go completely blind. The severity is variable among different people and families.

Genetic Disease: Retinitis pigmentosa is a group of inherited disorders that cause degeneration of the retina and vision loss. The condition can be inherited in multiple ways and has a variety of symptoms. The most common ones are night blindness and gradual loss of peripheral vision. There is currently no proven treatment, however gene therapy is being explored as a possibility.
