Beta carotene and retinitis pigmentosa
Date:10/18/2010

CHICAGOToday's Scientific Program of the 2010 American Academy of Ophthalmology (AAO) - Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting includes a report on beta carotene's ability to improve vision in people with certain incurable retinal diseases. The AAO-MEACO meetingthe world's largest, most comprehensive ophthalmic education conferenceis in session October 16 through 19 at McCormick Place, Chicago.

9-cis Beta-Carotene Mat Boost Vision in Some Patients with Incurable Retinal Disease Retinitis pigmentosa (RP) is a cluster of hereditary disorders of the retina (the light-sensitive tissue at the back of the eye) that can result in incurable blindness. RP usually begins with night blindness in childhood, then loss of peripheral (side) vision leading to tunnel vision, and ultimately blindness. Since a specific form of the nutrient beta carotene, 9-cis, has been effective against one type of night blindness, researchers decided to test its effects in RP patients. One third of the 29 participating patients showed improved visual function while taking the prescribed oral dose for 90 days, but the other two-thirds showed no effect.

"We recommend repeating the study with patients with the genetic forms of RP that would be most likely to respond to oral beta carotene," said Dr. Rotensteich. "We know its positive effect is associated with retinoid cycle defect, which is involved in some but not all forms of RP. Also, future research should look for the optimal beta carotene dosage," he added.
