Executive Summary

Study published in the June 14 Archives of Ophthalmology found that adults with blinding retinitis pigmentosa (RP) who supplemented their diets with 15,000 IU of vitamin A palmitate daily had, on average, about a 20% slower annual decline of remaining retinal function than those who did not. Conducted by Eliot Berson, MD, Harvard Medical School, et al., the study also recommended that adults with RP should avoid taking high-dose vitamin E supplements, which were found to speed progress of the disease in patients who took 400 IU vitamin E daily. The six-year study was funded by the National Eye Institute and the RP Foundation.
