Women under age 75 with high vitamin D status are less likely to have early age-related macular degeneration, the leading cause of irreversible vision loss.
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in adults, and the condition affects approximately 9% of Americans aged 40 and older. Amy E. Millen, from the University at Buffalo (New York, USA), and colleagues report that among women younger than 75, those who had blood concentrations of 25-hydroxyvitamin D above 38 nanomoles per liter were at a 44% reduced risk of having early age-related AMD (as compared to women with levels lower than 38 nanomoles per liter).
