The main symptoms of RP are night blindness (or difficulty adjusting to the dark) and loss of side vision. Loss of peripheral vision makes mobility, and daily activities such as driving, reading and recognizing faces and objects very difficult. At this point, central vision is most of what remains.
The symptoms RP are often first noticed in childhood or young adulthood. An individual affected by RP may have difficulty moving around in the dark, and may take an abnormally long time to adjust to changes in lighting conditions.
As the loss of peripheral vision becomes noticeable, patients often bump into things and appear clumsy. Additionally, people with RP often experience discomfort in bright lights.
Because there are so many different mutations that can result in RP, its progression can vary dramatically between those affected. Unfortunately, most people with RP eventually lose most of their sight.
