Retinitis Pigmentosa

A group of inherited genetic disorders that cause progressive degeneration of the retina, typically beginning with loss of night vision and peripheral vision and potentially leading to tunnel vision or complete blindness. RP affects the rod photoreceptor cells first, then may progress to affect cone cells. It is one of the most common inherited retinal dystrophies. People with RP may initially rely on screen magnification and increased contrast, and as the condition progresses, may transition to screen readers and other non-visual assistive technologies.
