There are a few studies going on in California. You can follow these links to read more on them -
Complete blindness does not occur in Retinitis pigmentosa. This is one positive thing. Those affected first experience night blindness, followed by constriction of the visual field and eventually the loss of central vision late in the course of the disease. Studies have suggested that treatment with antioxidants (such as vitamin A palmitate) may slow the disease from getting worse but they are debabtable. Several clinical trials are in progress to investigate new treatments for retinitis pigmentosa. Microchip implants that go inside the retina are in the early stages of development for treating blindness associated with this condition. Thanks.
