Don’t fight Retinitis pigmentosa 1 alone.Find your community on the free RareGuru App.
Retinitis pigmentosa (RP) is a group of inherited eye diseases that affect the light-sensitive part of the eye (retina). RP causes cells in the retina to die, causing progressive vision loss. The first sign of RP usually is night blindness. As the condition progresses, affected individuals develop tunnel vision (loss of peripheral vision), and eventually loss of central vision. RP may be caused by mutations in any of at least 50 genes. Inheritance can be autosomal dominant, autosomal recessive, or X-linked. Treatment options to slow the progression of vision loss include light avoidance, use of low-vision aids, and vitamin A supplementation. Researchers are working to develop new treatment options for the future such as gene therapy, stem cell transplantation and prosthetic implants.
