Can a supplement affect macular degeneration?

Researchers at Baylor College of Medicine and the National Eye Institute are seeking 4,000 volunteers between the ages of 50 and 85 who are diagnosed with the early stages of age-related macular degeneration in both eyes or have advanced AMD in at least one eye.

The Age-Related Eye Disease Study 2 (AREDS2) will look at the effects of vitamins supplemented by lutein/zeaxanthin and/or omega-3 fatty acids on the progression of the disease. Lutein and zeaxanthin are plant-derived yellow pigments that accumulate in the area of the eye's retina that is responsible for central vision, the same area where people with AMD begin to lose sight. Omega-3 fatty acids are the active components found in fish oil and are lauded for their heart-health benefits.

Volunteers will be provided two initial eye examinations followed by annual examinations for five years. All medications and daily multivitamins will be free of charge. Some people in the study will receive the active forms of the vitamins and omega-3 fatty acids. Others will receive an inactive form called a placebo. Results from the groups will then be compared at the end of the study.

AREDS2 is sponsored by the National Eye Institute. To enroll in the study or for more information, call 713-798-1501. The National Eye Institute's information line is 1-877-273-3780.
