Retinitis pigmentosa

What is Retinitis pigmentosa?

Retinitis pigmentosa is a disease that affects night vision and peripheral vision. The disease starts with decreased night vision progressing to diminished peripheral vision. The rate of decline varies depending on the genetic makeup of the disorder and also varies somewhat in individuals.

Causes of Retinitis pigmentosa

Retinitis pigmentosa is a genetic disorder that is usually hereditary.
The light sensitive retinal cells, known as Rods, are responsible for vision in dim light. The Rods in patients with retinitis pigmentosa will gradually deteriorate so that vision at night becomes more difficult.

Diagnosis of Retinitis pigmentosa

Symptoms start with decreased night vision, usually occuring early childhood. These symptoms usually progress to a diminishing of peripheral vision. Later stages of retinitis pigmentosa, will leave only the central area of vision and slight peripheral vision.

Treatments for Retinitis pigmentosa

There is some belief that vitamin A may delay vision loss.

Research is being carried out examining possible treatments including retinal implants and medication.
