Retinitis pigmentosa (RP) is a group of genetic disorders that affect the retina’s ability to respond to light. This inherited disease causes a slow loss of vision, beginning with decreased night vision and loss of peripheral (side) vision. Forms of RP and related diseases include Usher syndrome, Leber’s congenital amaurosis, rod-cone disease, Bardet-Biedl syndrome, and Refsum disease, among others.
HOW IS RETINITIS PIGMENTOSA DIAGNOSED?
The loss of night and peripheral vision would indicate this disorder and hence an ophthalmologist would dilate the eyes for a thorough examination to look for signs of this disorder. An electroretinogram and a visual field test could be performed to confirm the diagnosis of this disease.
HOW IS RETINITIS PIGMENTOSA TREATED?
There are no available cures for the problem of Retinitis Pigmentosa and the doctors try to control this issue by giving the patients supplements like Vitamin A, DHA, and Lutein. Along with this regular check up and eye drops are given to help in delaying this degeneration issue and sooner the treatment starts the higher are chances of minimising vision loss.
DID YOU KNOW?
The symptoms of RP typically appear in childhood. Children often have difficulty getting around in the dark. It can also take abnormally long periods of time to adjust to changes in lighting. As their visual field becomes restricted, patients often trip over things and appear clumsy. People with RP often find bright lights uncomfortable, a condition known as photophobia.
