Retinitis pigmentosa (RP) is a group of inherited retinal disorders characterized by the progressive photoreceptors and pigment epithelial cells dysfunction. It is the most common retinal degeneration, responsible for loss of vision of most people worldwide. Until now its exact pathogenesis and etiology are not clear. So far there is no approved therapy. New approaches for RP therapy include cell transplantation, gene therapy, cytokine therapy, nutrition therapy, and hyperbaric oxygen therapy. Such therapies for retinal degenerative diseases are limited in their efficacy. This paper reviews the relevant documents, especially recent researches, and reviews advances in the treatment of RP.
