The majority of the people with retinitis pigmentosa disease notice a loss of night vision first, and this becomes apparent quite often in childhood. Navigating or reading in low light can be a problem. As the disease progresses there will be blind spots in the peripheral vision. The loss of the peripheral vision is often called “tunnel vision.” Children may not realize anything is wrong, but they cannot play soccer very well, or they may often trip over things that are located in that blind spot. Some people have a problem with concentric glaring lights. The course of this disease is not the same for everyone and symptoms may progress at different rates. Often the disease progression is slow, but after decades the central vision will be affected. Most people are considered legally blind by the age of 40.
