How is Retinitis Pigmentosa treated?
There is no known cure for retinitis pigmentosa. However, there are few treatment options such as light avoidance and/or the use of low-vision aids to slow down the progression of RP. Some practitioners also consider vitamin A as a possible treatment option to slow down the progression of RP. Research suggests taking high doses of vitamin A (15,000 IU/day) may slow progression a little in some people, but the results are not strong. Taking too much vitamin A can be toxic and the effects of vitamin A on the disease is relatively weak. More research must be conducted before this is a widely accepted form of therapy. Research is also being conducted in areas such as gene therapy research, transplant research, and retinal prosthesis. Since RP is usually the result of a defective gene, gene therapy has become a widely explored area for future research. The goal of such research would be to discover ways healthy genes can be inserted into the retina. Attempts at transplanting healthy retinal
