Many older adults have a condition called macular degeneration. This eye disease results in significant loss of central vision, and treatments do not typically restore vision lost to this condition. If you have risk factors or warning signs of this condition, you should take precautions to avoid progression. Some people turn to herbs as one method of prevention, and knowing the possible benefits and risks will help you determine if herbal prevention is the best choice for your eyes.
Cause
One cause of macular degeneration occurs when the cells that make up the macula break down. This type, called dry macular degeneration, results in blurry vision, muted colors and the need for extra light, explains the University of Maryland Medical Center, or UMMC.
Wet macular degeneration results from the growth of abnormal blood vessels beneath the macula. These vessels then leak, causing the macula to swell and lift out of place, damaging the tissue. The wet form often occurs suddenly, causing loss of central vision or distortion of straight lines.
Ginkgo Biloba
Ginkgo biloba is one herb that may help slow down or reduce your risk for macular degeneration damage. Ginkgo biloba extract comes from the ginkgo tree and is available in liquid, tablet or dried form. Your doctor can help you determine a dose that is appropriate for your eyes and overall health. An average dose may range from 160 to 240 mg per day. Ginkgo may interact with certain medications, so you should discuss the risks with your doctor before starting this supplement.
Bilberry
Bilberry is a fruit native to Europe, but a close relative to blueberries found in the United States. The flavonoids found in bilberry extract may help prevent damage from macular degeneration, explains UMMC. You and your doctor should discuss the dose of bilberry you will need for optimum eye benefits. The dose of this extract may range from 120 to 240 mg twice a day.
Additional Prevention
Your doctor may determine that the flavonoids and other nutrients in grape seed extract may provide additional prevention against macular degeneration. This supplement comes in pill and liquid form. As with other herbal supplements, your dose of grape seed extract will vary, but may range between 50 and 150 mg each day.
Considerations
Inform your doctor of your intentions to use herbal supplements for macular degeneration. Some supplements may interact with medications or health conditions, and discussing the possible risks with your doctor will help protect your overall health.
