Learn More About Macular Degeneration
Some studies have shown a reduced risk of age-related macular degeneration in subjects with a higher intake of lutein and zeaxanthin or higher plasma concentrations of lutein and zeaxanthin. Lutein is a carotenoid found in vegetables and fruits. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. Zeaxanthin is another carotenoid that is likely to be equally as effective as lutein in preventing macular degeneration. In persons who eat large amounts of fruits and vegetables, it has been found that the risk of age-related macular degeneration decreases some 43 percent.
Individuals at high risk of age-related macular degeneration (AMD) who took a high-dose combination of vitamins C and E, beta-carotene and the mineral zinc lowered their risk of the disease by 25%. AMD is the leading cause of blindness in elderly Americans. AMD occurs when abnormal blood vessels leak fluid and blood into the tissue at the back of the eye, leading to blistering and scarring of the retina. The disease affects central vision needed for reading, driving and recognizing faces.
Researchers found that regular aspirin use, defined as twice a week for more than three months, for 10 years increased participants' risk of neovascular age-related macular degeneration (AMD).
