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 often first appear in childhood, but severe vision problems do not usually develop until early adulthood.
Decreased vision at night or in low light
Loss of side (peripheral) vision, causing "tunnel vision"
Loss of central vision (in advanced cases)
Currently, there is no treatment available to treat this eye disease.
However, according to some ophthalmologist increased consumption of Vitamin A may delay vision loss.
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.
