Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged.
The study looked at 866 cases of primary open-angle glaucoma, the most common type of glaucoma, among more than 136,000 study participants who were followed for 15 or more years.
Participants provided researchers with updates on statin use and cholesterol levels every other year throughout the study period.
After analysing the information, study authors found that for every 20-point increase in total cholesterol there was a seven percent increase in glaucoma risk.
