New dietary supplement studied for age-related macular degeneration
October 1st, 2008
Researchers are investigating the potential of a new combination supplement to slow the progression of age-related macular degeneration, an eye disease that can lead to loss of central vision.
A supplement composed of vitamins C and E, zinc and copper, and the antioxidant beta-carotene is already recommended for patients with large drusen – small bright structures in the retina – in both eyes and those with advanced disease.
However, recent research has identified three other nutritional ingredients that may benefit patients with age-related macular degeneration. These include xanthophylls, a yellow pigment found in some plant leaves; and two types of omega-3 fatty acid, which are found in oily fish and are known to improve the health of the heart.
The investigators are studying the benefits of the supplement in about 4000 people aged 50-85 years with large drusen in both eyes, or large drusen in one eye and advanced age-related macular degeneration in the other eye.
The results, which will shed further light on the value of vitamins, minerals and omega-3 fatty acids for treating age-related macular degeneration, are expected in 5 years.
