Retinitis pigmentosa (RP) is a group of inherited retinal disorders characterized by progressive loss of photoreceptors and eventually leads to retina degeneration and atrophy. It especially affects the light-sensitive cells of the retina known as Rods and Cones. They send the information to the brain regarding every minute detail of your visualization through the help of optic nerves.
Cell transplantation therapy in retinitis pigmentosa has made progress. Researchers have found that the transplanted cells can be used as a substitute for degenerated cells or they can release some growth factors to enhance cell survival, growth, and function of retinal cells.
