Vitamin D may increase chances for healthy eyesight
Having an immediate relative with age-related macular degeneration, or AMD, can signal a greater genetic tendency to develop the disease because an inefficient immune system does not effectively eliminate pathogens. Doctors also believe inflammation plays a role in AMD, and wanted to test for a link
to the anti-inflammatory, vitamin D. Researchers compared 913 women with and without the genetic tendency to develop AMD, and measured vitamin D levels. Women who were deficient in vitamin D and who also had the genetic tendency toward AMD were more than six times as likely to develop the disease compared with women with healthy genes and good vitamin D levels. Discussing the findings, doctors said for women whose genetic makeup raises chances for AMD, maintaining adequate vitamin D levels may increase chances for healthy eyesight.
