Supplementation and Nutrition for Macular Degeneration...

Age related macular degeneration (AMD) is the most common cause of vision loss among the elderly. Although we do not have a cure, studies like AREDS (Age Related Eye Disease Study), have shown that nutritional supplementations can reduce the progression of the disease. Yet, as the word indicates, supplementation should be used to enhance an individual’s diet not to substitute it. The best source of nutrients comes from dietary intake and supplementation should be secondary to food modifications.There are an array of nutrients that have been shown to protect the eye from various degenerative diseases like AMD. Examples include but are not limited to fish, leafy green vegetables, nuts, blueberries and low glycemic foods. It is important to note that changes in a diet should be discussed with your physician to prevent any adverse effects. For example, high levels of vitamin K (found in leafy greens) may intensify the effects of blood thinning medications.Although it is preferable to get vitamins and minerals from food, it may be difficult to obtain the high doses needed from diet alone. These particular supplements are not one-size fits all. Although some patients may require nutritional supplementation, not everybody needs an AREDS style supplement and not all individuals should take it. Furthermore, mega-doses of vitamins may be contraindicated and/or harmful in particular cases. More is not always better and mega-doses may be associated with adverse affects. The proper recommendation may depend on age, gender, systemic health, social behavior, as well as current supplements and medications one is taking. Any ocular vitamin supplementation should be discussed with your eye care provider. In addition to a good diet and possible nutritional supplementation, lifestyle changes are beneficial in decreasing the prevalence and progression of AMD. These include smoking cessation, controlling blood pressure, exercising, maintaining a proper body mass index (BMI), avoiding processed foods, and limiting foods that have a high glycemic index (such as processed foods). In absence of health related issues or contraindications, addition of various vitamins, minerals, and herbs through a well-balanced diet may play a key role in helping in the fight against AMD. As always, getting a regular eye exam is still a must.
