Retinitis Pigmentosa

Abstract Retinitis pigmentosa is a heterogeneous group of retinal dystrophies that are characterized by photoreceptor cell degeneration, night blindness, a gradual loss of peripheral visual fields and eventual loss of central vision. Several genes responsible for the development of retinitis pigmentosa have now been identified and cloned, and these discoveries have defined the genetic pathways for pathogenesis of retinitis pigmentosa.
