Researchers Discover New Treatment for Retinitis Pigmentosa; Study Published in Two Papers in Archives of Ophthalmology September 2004 Issue.

The article cites a study reported in the recent issue of the Archives of Ophthalmology, which states that Vitamin A palmitate is estimated to provide 7 years of additional vision for those who began this supplement in their 30s. Docosahexaenoic Acid (DHA), an omega-3 fatty acid, is in high concentration in the retina and is thought to provide a fluid, fat-soluble environment for vitamin A to change its shape as the initial step in the retinal response to light. In summary, among all randomized patients DHA supplementation by capsules in a dose of 1200 milligram per day, given in combination with vitamin A palmitate 15,000 IU per day, did not, on average, slow the course of this condition over a four-year interval.
