Retinitis pigmentosa (RP) is a rare, inherited disease in which the light-sensitive retina of the eye slowly and progressively degenerates. Eventually, blindness results.
Symptoms of Retinitis Pigmentosa
The first signs of retinitis pigmentosa usually occur in early childhood, when both eyes typically are affected. Night vision can be poor, and the field of vision may begin to narrow.
When RP first starts to appear, the light-sensing cells that are responsible for vision in dim light gradually deteriorate and seeing at night becomes more difficult.
During later stages of retinitis pigmentosa, only a small area of central vision remains, along with slight peripheral vision.
