Retinitis Pigmentosa

Below we explain what Retinitis Pigmentosa is, what the symptoms are and how the condition is diagnosed.

Retinitis Pigmentosa (RP) comprises a group of inherited disorders which are characterised by progressive degeneration of the retina, the light sensitive membrane lining the inside of the eye. This causes gradual loss of vision, although how quickly this happens and how much sight is lost varies from person to person.

Some people with RP can become blind, but many keep some useful vision into old age. This is because there are a large number of varieties of RP and specialist assessment and advice is required from an Ophthalmologist to give an affected individual an accurate prognosis.

Symptoms

  • Progressive difficulty in seeing in dim light, night blindness
  • Gradual restriction of peripheral vision leading to tunnel vision
  • In some varieties, loss of central vision

Assessment

Diagnosis is made by examination of the back of the eyes by a specialist and may be confirmed by tests of the electrical activity of the retina. The tests are non-invasive and painless.

Treatment

Though research is on-going, there is currently no treatment available to arrest RP or to slow its progress.
