Some people are genetically at risk for vision loss as they age and a vitamin D deficiency dramatically increases that risk, according to a study from the University of Buffalo. Genetic data and vitamin D status were assessed in a group of 913 women between the ages of 54- and 75-years-old. That information was compared to risk for developing age-related macular degeneration. Results showed that the risk for macular degeneration was 6.7-fold greater in women who were low in vitamin D and had a genetic profile associated with increased risk. These results suggest a synergistic effect between vitamin D status and genetics when it comes to vision in later life.
