Macular degeneration is a condition that slowly destroys the central tissue on the back lining of your eye. This tissue, called the macula, consists of light-sensitive cells that help you see faces and any other objects directly in front of you. Treatment does not restore vision, but certain nutrients, such as lutein and zeaxanthin, might help prevent the disease. If you have early warning signs or other risk factors, talk with your doctor about the potential benefits and risks.
Symptoms
The early stages of macular degeneration may cause blurry vision and changes in color. You might need additional light for reading or other tasks. In advanced cases of macular degeneration, straight lines might appear bent or wavy, and you may have severe vision loss in your straight-ahead, central vision. Many people do not lose side vision, and those with severe vision loss may rely on their side vision to help them with daily tasks.
Lutein and Zeaxanthin
Lutein and zeaxanthin are pigments that might offer protection against macular degeneration damage. Your body cannot make these nutrients, so you must eat foods or take supplements that contain lutein and zeaxanthin. Food sources include green, leafy vegetables such as spinach and kale. Other foods include corn, green peas and broccoli. Your doctor can help you determine how much lutein and zeaxanthin you require each day, and she will determine this amount based on your health and any medications or supplements you take.
Additional Nutrients
In addition to lutein and zeaxanthin, other nutrients might help protect your macular tissue. The Age-Related Eye Disease Study, conducted by the National Eye Institute in 2001, determined that high doses of vitamins A, C and E, as well as zinc, might help reduce your risk of macular degeneration. Shortly after the National Eye Institute released these findings, manufacturers created an "eye vitamin" that contains these nutrients. Some of these supplements also contain lutein.
Considerations
A diet rich in lutein and zeaxanthin will not typically cause complications. However, a high intake of these and other nutrients might cause complications with certain medications and health problems, such as blood conditions. Discuss your health history and medications with your doctor before making dietary changes or adding supplements to avoid troubling interactions.
