Retinitis pigmentosa

Common Name(s)

Retinitis pigmentosa

Retinitis pigmentosa (RP) is the name given to a group of inherited eye diseases that affect the light-sensitive part of the eye (retina). RP causes cells in the retina to breakdown and die, eventually resulting in vision loss. The first sign of RP is usually night blindness. As the condition progresses, affected individuals also develop tunnel vision. Sometimes RP occurs by itself (isolated RP), and other times it occurs with additional signs and symptoms (syndromic RP). Mutations in at least 50 genes have been found to cause RP. There is no cure for RP, however, there are a few treatment options to slow down the progression of the disease. These options include light avoidance, use of low-vision aids, and vitamin A supplementation.
