AMD Macular Degeneration & Diet Factors

“Dietary factors are known risk factors for Age Related Macular Degeneration (AMD) which is the leading cause of vision loss among persons aged 65 and above”, commented Birmingham Ophthalmologist Tyler Hall, M.D. of Alabama Eye & Cataract Center.  “In particular high glycemic index diets have been thought to be a contributing risk factor for AMD.”  Glycemic Index is a measure of the effect of carbohydrates on blood sugar levels. Most fruits and vegetables, legumes, whole grains, nuts and fructose products low in carbohydrates and have a low glycemic index. Most foods like baked potatoes, extruded breakfast cereals, white bread, white rice and corn flakes are high glycemic index foods. Researchers reporting in the American Journal of Clinical Nutrition studied the association between dietary glycemic index and the 10 year incidence of AMD in the Blue Mountain Eye Study population. Over 10 years, 208 of 1810 persons developed early AMD. After age, smoking, other risk factors, and dietary constituents were adjusted for, a higher mean dietary glycemic index was associated with an increased 10 year risk of early AMD.  Conversely, a greater consumption of cereal fiber and breads and cereals (predominantly lower glycemic index foods such as oatmeal was associated with a reduced risk of incident early AMD. No relation was observed with late AMD. The researchers concluded that a high glycemic index diet is a risk factor for early AMD—the recognized precursor of sight threatening late AMD. Low-glycemic-index foods such as oatmeal may protect against early AMD.

Preventing Diabetic Retinopathy

Birmingham Ophthalmologist Tyler Hall, M.D. shared information about preventing diabetic retinopathy. Diabetes is one of the most common chronic diseases among children and adults in the United States.  In diabetics there is too much sugar in the blood. When the blood sugar is constantly or frequently high, many complications occur: eyesight can suffer due to changes in the crystalline lens and the retina, cardiovascular disease can lead to heart attacks, strokes and other blood vessel problems in the kidney may also occur. When blood sugar is maintained at a normal level (between 80 and 120) most of the time, the complications of diabetes can be reduced. Controlling blood sugar is the most important thing a person with diabetes can do to prevent or reduce the complications of diabetes.

Type I Diabetes usually begins at a young age and patients must take insulin to survive and control blood sugar. They should test their own blood sugar with a blood sugar-monitoring device several times daily so they can adjust their diet, exercise and insulin doses to keep the blood sugar under control. They should follow a diet controlled in carbohydrates and low in fat and cholesterol. Regular exercise is also very important as it helps reduce blood sugar.

Type II diabetes usually starts in adult life and is often not dependent on insulin. Maintaining normal weight and a diet low in calories, fat, and cholesterol is the key. Blood sugar can be controlled either with diet alone or in combination with pills to lower blood sugar. In some cases, insulin treatment is also necessary.

In addition to the importance of diet and exercise, there are other factors that can affect diabetes. High blood pressure increases the likelihood of complications and therefore should be strictly controlled and kept normal at all times. Anyone with diabetes, especially those who have had diabetes for a long time, should have regular eye examinations-at least every year and more often if directed to do so by your eye doctor in order to identify the signs of diabetic retinopathy as early as possible. The early diagnosis and treatment of diabetic retinopathy is the key to maintaining eye health and vision for those with diabetes.
