I have Retinitis Pigmentosa and there is no cure yet. However, there are some supplements which can really help. I personally like Rogisen which does a pretty good job of aiding night vision. Billberry is also good, and I think it's in Rogisen as well... Vitamin A Palmitate is another thing you want him to take. It will help control eye issues dealing with macular degenration. Hope that helps.
