Daily intake of 20 grams of alcoholic beverages, including wine, beer, and spirits, may increase an individual's predisposition to age-related macular degeneration (AMD).

This study assessed alcohol consumption in relation to the development of age-related macular degeneration (AMD). A total of 20,963 Australian men and women aged 40-69 years took part in this study. They provided information on their alcohol drinking habits and underwent regular eye examination over a 4-year period. 

The team of researchers observed that the probability of suffering from age-related macular degeneration rose by 20% among participants who drank 20 grams of alcoholic beverages, including wine, beer, and spirit, daily. The findings of this study show that high intake of alcohol may facilitate the onset of age-related macular degeneration.
