Gene Variation May Alter Treatment of Macular Degeneration
Researchers from the United States and China have isolated the location of a gene that may protect against dry macular degeneration.
The gene mutation has no effect on the onset or progress of wet age-related macular degeneration. The identification of this gene comes with a warning for some patients with wet AMD: the experimental gene-suppressing drugs being tested currently may halt the spread of wet AMD, but at the cost of increasing the patient's risk for the dry form of the condition.
Age-related macular degeneration (AMD) affects about 250 million people around the world and is the leading cause of vision loss in the United States. Macular degeneration occurs due to thinning of the macula, or the inner lining of the retina. The condition has two distinct forms – dry and wet. Dry macular degeneration is associated with the presence of small collections of debris, called drusen, in the macula. Wet macular degeneration causes vision loss due to abnormal blood vessel growth and leakage.
While it is true that macular degeneration has no cure, several treatments have proven effective at limiting or halting the progress of the disease.
Current research shows a link between carotenoids, like Lutein and Zeaxanthin, as well as beta-carotene and Omega-3 fatty acids, for effective macular degeneration treatment and prevention. If you are at risk for AMD, supplementing your diet with eye health vitamins rich in these substances can substantially reduce the risk of developing the condition.
