Retinitis pigmentosa (RP) is a rare, inherited disease in which the light-sensitive retina of the eye slowly and progressively degenerates. Eventually, blindness results.
Retinitis pigmentosa is a genetic disorder of the eyes that causes loss of vision. Symptoms include trouble seeing at night and decreased peripheral vision. Onset of symptoms is generally gradual. As peripheral vision worsens, people may experience tunnel vision. Complete blindness is uncommon. Retinitis pigmentosa is generally inherited from a person's parents. Mutations in one of more than 50 genes is involved. The underlying mechanism involves the progressive loss of rod photoreceptor cells in the back of the eye. This is generally followed by loss of cone photoreceptor cells.
