Retinitis Pigmentosa

Retinitis pigmentosa is a hereditary rod-cone dystrophy causing progressive night blindness, peripheral visual-field loss (tunnel vision), and bone-spicule pigmentation in the mid-periphery, waxy pale disc, and arteriolar attenuation. There is no established cure. Treatment: vitamin A palmitate (mild benefit), low-vision aids, and dark-adaptation counseling; gene therapy is emerging for selected mutations; genetic counseling.

Common Symptoms

Night blindness; tunnel vision; bone-spicule pigmentation; waxy disc; arteriolar attenuation

Causes and Pathogenesis

Hereditary photoreceptor (rod-first) degeneration produces progressive field loss and pigment migration.

Treatment

Vitamin A; low-vision aids; gene therapy emerging; genetic counseling

Preventive Measures

Genetic counseling; low-vision rehab; avoid bright light.
