Beta Carotene and Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a name for a large group of inherited vision disorders that cause progressive degeneration of the light sensitive membrane that coats the inside of the eye -- the retina. For most people with RP, night blindness is the first symptom of the problem. Then side vision goes, resulting in tunnel vision and, eventually, central vision deteriorates. Complete blindness, though uncommon, can occur.
