Blindness: Retinitis pigmentosa (RP) causes vision loss that worsens over time. Some people may eventually become blind, although this is rare.
Cataracts: Patients with RP often develop a type of cataract called subcapsular cataracts. When this occurs, the lens becomes cloudy and vision is impaired. Eyeglasses may improve symptoms when cataracts first develop. Later on, surgery may be needed to restore vision.
Retinal detachment: Some patients may experience retinal detachment, which occurs when the retina separates from its attachments to the back of the eyeball. Without prompt treatment, retinal detachment may lead to permanent vision loss.
Interference with daily activities: RP may eventually interfere with daily activities. It may become difficult to drive, especially at night. Individuals are required to pass an eye test before obtaining a new license or renewing an existing license. Some people who have poor night vision may require restrictive driver's licenses that only permit them to drive during the day.
