Retinitis pigmentosa

An eye disease in which the back wall of the eye (retina) is damaged.

Retinitis pigmentosa is a rare, inherited degenerative eye disease that causes severe vision impairment.

Symptoms often begin in childhood. They include decreased vision at night or in low light and loss of side vision (tunnel vision).

There is no effective treatment for this condition. Wearing sunglasses may help protect remaining vision.
