Retinitis pigmentosa (RP) refers to a group of inherited diseases that lead to slow and progressive retinal degeneration that causes damage to the important cells of the retina, the rods and the cones.
People diagnosed with RP usually experience night blindness early on, and later may develop progressive and gradual reduction in their vision and field of view. Many people with RP do not become legally blind until their 40s or 50s and retain some sight all their lives. Others go completely blind from RP, in some cases as early as childhood. Progression of RP is different in each case.
The diagnosis of retinitis pigmentosa relies upon documentation of progressive loss in photoreceptor cell function by electroretinography (ERG) and visual field testing.
