Key takeaways:
- A study suggests greater use of red wine or beer is linked to higher IOP but not glaucoma.
- Women had higher IOP increases compared with men.
NEW ORLEANS — Greater use of certain types of alcohol is associated with elevated IOP but not glaucoma, according to a poster presentation at the Association for Research in Vision and Ophthalmology meeting.
“We had a categorical covariable where we compared daily, occasional and weekly drinkers to never drinkers,” study author Alyssa Grant told Healio/OSN. “We found daily drinkers had higher IOP by about 0.46 mm Hg.”

Grant and colleagues conducted a cross-sectional analysis of 30,097 randomly selected people at 11 data collection sites across Canada. Participants’ alcohol consumption frequency, type of alcohol consumed and IOP were analyzed. Participants were also asked if they had been diagnosed with glaucoma.
Across all alcohol types analyzed, an increase of five drinks per week in daily red wine or beer was associated with higher IOP. No statistically significant association was found between white wine, liquor or other alcohol types and IOP. After adjustment, no associations were found between alcohol consumption frequency, alcohol type or total alcohol intake and glaucoma.
“We also did find a sex interaction with alcohol, in that females had higher IOP increases when they consumed alcohol compared to males,” Grant said. “They were also less able to withstand the IOP elevations.”
