Retinitis Pigmentosa

What is Retinitis Pigmentosa?

Retinitis Pigmentosa (RP) is a genetic eye condition that causes cells in the light-sensitive retina, located at the back of the eye, to degenerate slowly and progressively. The condition can vary greatly. While many people with RP retain limited vision throughout their lives, others will lose their sight completely.

What are the symptoms?

Generally, symptoms develop between the ages of 10 and 30 years. Some of the first symptoms may include the following:

  • difficulty seeing at night (night-blindness) or in dimly lit areas
  • a narrowing field of vision
  • light and glare sensitivity

Who is at risk?

RP is an hereditary disease that generally occurs in people that have a family history of the condition.

Can it be treated?

There is currently no standard treatment or therapy for RP. However, scientists have isolated several genes responsible for the disease and research is being done on stem cell and gene therapy.
