A study published July 29, 2012 in American Journal of Epidemiology has concluded that drinking more than 20 g of alcohol per day was associated with an approximate 20% increase in the odds of early AMD when compared with those who reported no alcohol intake at baseline. A typical glass of wine contains about 15 g. The positive association, drawn by researchers at the Centre for Eye Research Australia, was apparent for wine, beer, and spirits. Read the abstract here.
This is interesting in light of previous research showing red wine to be beneficial to the retina for its antioxidant properties. It is not, however, the alcohol content that provides this benefit, so, as substantiated by these new findings, one glass per day should be the limit.
