Retinitis Pigmentosa is an hereditary disease in which a specific gene defect causes the cells in the Retina of the eye to misfire.
There isn’t a defined cure or treatment. However, many find the onset to be quite slow. The symptoms begin with central vision losses, but there are cases where the side, or periphery of the vision can deteriorate slowly …. creating a tunnel vision effect.
Poor vision in environments with dim lighting at the later stages in life are considered early symptoms of RP. These can be connected to other eye problems which, together, in some cases, are called syndromes. The loss of hearing along with RP is called the Usher’s Syndrome and tends to have a genetic cause.
