Retinitis Pigmentosa
Tests and Treatment
Left: Retinitis pigmentosa causes deterioration of light-sensitive cells in the back of the eye. Right: While no cure is known for people blinded by retinitis pigmentosa, studies have centered on creation of artificial retinas that may at least partially restore sight. The Argus II Retinal Prosthesis System shown here received FDA clearance in early 2007 to begin clinical trials.

Other eye exams may be conducted to determine whether you have lost night or color vision.
No treatments currently are available for retinitis pigmentosa, although some practitioners believe that vitamin A may slightly delay vision loss. Occupational therapy may be helpful, because it's easier to adjust to declining vision in earlier stages of vision loss.
Individuals with retinitis pigmentosa also might consider use of low vision devices that can help magnify and illuminate objects in home and work spaces.
Researchers are looking into ways to treat RP in the future, such as retinal implants and drug treatments. Read about recent success with implants for people with retinitis pigmentosa and an artificial retina that is being tested in clinical trials.
