Filter by:The goal of the study is to determine the effect of different doses of caffeine on intraocular pressure. We hypothesized that higher dosage of caffeine would increase intraocular pressure more than lower doses. Eligible subjects will be randomized into three groups: 1. group 1: intake of decaffeinated coffee 2. group 2: intake of coffee with lower caffeine dose 3. group 3: intake of coffee with higher caffeine dose Intraocular pressure will be measured at 0, 30, 60 and 90 minutes after coffee intake.
