Retinitis pigmentosa not associated with systemic disease (Q99761)

This is an inherited, degenerative eye disease that causes severe vision impairment and often blindness. The progress of RP is not consistent. Some people will exhibit symptoms from infancy, others may not notice symptoms until later in life. Generally, the later the onset, the more rapid is the deterioration in sight. This diagnosis is not associated with a disease that affects a number of organs and tissues, or affects the body as a whole.
