Low Vitamin D Levels Linked to Macular Degeneration Risk - June 2016
Adults with the lowest concentrations of circulating vitamin D had the highest risk for age-related macular degeneration (AMD), according to a new systematic review and meta-analysis published online April 2 in Maturitas.
In a second analysis, those in the highest quintile of circulating vitamin D levels had the lowest odds of AMD compared with those in the lowest quintile. Those with the highest vitamin D levels had 83% lower odds of AMD and 47% lower odds of late AMD compared with those with the lowest levels.
Low vitamin D levels may contribute to AMD, yet they do not fully explain development and worsening of the condition. Further, it is unclear whether vitamin D supplementation would be protective against developing AMD.
