Retinitis Pigmentosa (RP)
What is it?
Retinitis Pigmentosa is a group of genetic eye conditions causing progressive degeneration of the retina, the light sensitive layer of tissue lining the back of the eye. The light receptors of the retina are called rods and cones.
As a result of Retinitis Pigmentosa the rods, and in a later stage the cones, slowly die, causing reduced vision. The peripheral vision decreases first; central vision is usually retained until late in the disease.
Retinitis Pigmentosa is an inherited condition affecting both eyes. If it starts in one eye, the other eye generally develops the same condition in a number of years. It is often diagnosed during the teenage years, but may be present at birth. Cases diagnosed at birth are often stable and non-progressive. Cases diagnosed later in life are often mild and may progress more slowly than those diagnosed in the teenage years.
