What is Retinitis Pigmentosa? (Definition)
Retinitis pigmentosa (RP) refers to a group of rare, inherited genetic disorders that involve a breakdown and loss of cells in the retina (the light sensitive tissue that lines the back of the eye). The retina is responsible for capturing images from the visual field. Common symptoms include difficulty seeing at night and a loss of side (peripheral) vision. Some forms of retinitis pigmentosa and related diseases include Usher syndrome, Leber’s congenital amaurosis, rod-cone disease, Bardet-Biedl syndrome, and Refsum disease.
Symptoms and Signs of RP
Symptoms of RP vary, but typically include the following:
- Nyctalopia (night blindness – most commonly the earliest symptom in RP)
- Visual loss, usually peripheral; in advanced cases, central visual loss
- Photopsia (seeing flashes of light)
