Macular degeneration is a condition that too often results in permanent loss of vision. The macula sits on the back lining of your eye, and these tissues help provide the clear central vision you use for everyday tasks, such as watching television or reading. Treatment does not typically restore lost vision, which makes prevention a key factor in preserving your vision. Certain nutrients, such as omega-3 fatty acids, may aid in preventing macular degeneration.
Types
Dry macular degeneration occurs when you have damage to the cells in the macular tissue. This will cause a gradual decrease in vision, which some people may see as a blind spot or blurred area in the center of vision.
Wet macular degeneration typically occurs suddenly as a result of abnormal vessels growing and leaking blood underneath the macula. This will damage the macula and displace the tissue, resulting in blurry, distorted vision, such as apparently bent telephone poles or light posts.
Dietary Sources
Omega-3 fatty acids may help prevent the breakdown of the cells in the macula that leads to vision loss. Your body cannot make omega-3, so you must consume these fatty acids through diet or supplements. For example, salmon, tuna and mackerel contain omega-3, as well as flax seeds and walnuts.
Supplements
To ensure that you have a daily intake of omega-3, your doctor may recommend that you take supplements. A common supplement for omega-3 is fish oil capsules. For a plant-based supplement, you can also use flax seed oil capsules.
Additional Nutrients
In 2001, the National Eye Institute discussed the findings of a study that evaluated the benefits of certain nutrients in preventing macular degeneration. The Age-Related Eye Disease Study determined that vitamins E, C and A, along with zinc may reduce the risk of advanced macular degeneration by about 25 percent.
Considerations
Before making changes to your diet, discuss your nutritional needs with your doctor. She will help you determine an appropriate dietary or supplement plan. Omega-3 could interact with certain medications, such as blood thinners like Coumadin, so always discuss nutritional changes with your doctor to ensure they will not interfere with treatment for another condition.
