Retinitis pigmentosa

Signs of retinitis pigmentosa (RP) usually appear during childhood or adolescence. The first sign is often night blindness, followed by a slow loss of side vision. As the disease develops over the years, people with RP often bump into chairs and other objects because their side vision is worsening. They can only see straight ahead as if they are in a tunnel. Fortunately, most cases of RP take a long time to develop and vision loss is gradual. It may take many years for vision loss to become severe. Currently, there is no cure for RP. However, research indicates that vitamin A and lutein may slow the disease's progression. A doctor of optometry can provide more specific information on nutritional supplements that may help slow the disease and can monitor the progression thereafter. Also, low vision aids, including telescopic and magnifying lenses, night vision scopes and other adaptive devices, can help people with RP maximize their remaining vision. A doctor of optometry who is experienced in low-vision rehabilitation can provide these devices. He or she can also provide information about other training and assistance to help people remain independent and productive. Genetics research may one day provide a prevention or cure for people who have this inherited disease.

Causes & risk factors

Factors Retinitis pigmentosa is an inherited condition.

Symptoms

Signs of RP usually appear during childhood or adolescence. The first sign is often night blindness, followed by a slow loss of side vision. As the disease develops over the years, people with RP often bump into chairs and other objects because their side vision is worsening. They can only see straight ahead as if they are in a tunnel. Fortunately, most cases of RP take a long time to develop and vision loss is gradual. It may take many years for vision loss to become severe.

Diagnosis

• Comprehensive eye examination
• It can be a difficult diagnose and may require further testing
• Family history of the disease

Prevention

There is no prevention for retinitis pigmentosa because it is hereditary.
