Retinitis pigmentosa is an eye disease in which there is damage to the retina. The retina is the layer of tissue at the back of the inner eye that converts light images to nerve signals and sends them to the brain.
Symptoms of Retinitis pigmentosa often first appear in childhood, but severe vision problems do not usually develop until early adulthood. Symptoms that are reported are the following; decreased vision at night or in low light, loss of side (peripheral) vision which causes “tunnel vision”, and loss of central vision (in advanced cases) .
Currently, there is no treatment available to cure this eye disease. However, according to some ophthalmologists, increased consumption of Vitamin A may delay the loss of vision. There is high possibility that occupational therapy may prove helpful, as it is easy to adjust to waning vision in former stages of vision loss.
