The leading cause of blindness for seniors is age-related macular degeneration. Based on recent research there appears to be a strong correlation between age-related macular degeneration and chronic vascular disease. Macular degeneration seems to be tied to the gradual degradation of blood vessels in the eye. A number of researchers investigated patients for any common risk factors for vascular disease and macular degeneration. They discovered that patients already suffering from macular degeneration had elevated levels of homocysteine. Elevated levels of homocysteine are known to be a marker for for cardiovasular risk. Additional studies verified that the higher homocysteine levels were a marker for increased risk of macular degeneration in seniors. In parallel studies researchers found that C-reactive protein inflamatory marker for cardiovascular diseasewas equally predictive as a marker for increased risk for macular degreneration in seniors.
The researchers next investigated the possible causes of the elevated homocysteine levels. They focused on the possible vitamin deficiences that might be contributing to the elevated homocysteine levels. They discovered that the seniors suffering from macular degeneration were deficient in levels of vitamin B6, B12, and B9 (folic acid). In a study of over 5,000 women over the age of 40 who were known to be a risk for cardiovascular disease, those who supplemented with the three members of the vitamin B family had their risk of macular degeneration reduced by over 40%. This is good news for seniors, because supplementing with the three B vitamins and eating foods rich in those vitamins will promote healthy eyes that are necessary for senior health.
