Retinitis pigmentosa (RP) patients typically become blind after a period of years in which their eye sight slowly deteriorates. Generally they develop night-blindness first, then tunnel vision, after which finally the central eye sight diminishes leaving them with basically no eye sight, bar some crude light perception. See the wiki page on RP. Now I am reading an article where they say that they have a group of congenital blind subjects, out of which one has RP. Is anyone familiar with newborns blinded by the effects of RP?
