Retinitis Pigmentosa (RP) refers to a group of inherited diseases causing retinal degeneration.The retina lines the back inside wall of the eye and is responsible for capturing images from the visual field.People with RP experience a gradual decline in their vision because photoreceptor cells (rods and cones) die.
A discovery of a new gene that causes Leber congenital amaurosis (LCA) and retinitis pigmentosa (RP), two devastating forms of childhood blindness, has been made at Montreal Children's Hospital.
