Study Endpoints
Primary Endpoints
Mean Intraocular Pressure (IOP) Change From Baseline at All 9 Time Points During the Study (0800, 1000 and 1600 Hrs at Weeks 2, 6, and 12)
Baseline, Weeks 2, 6, and 12.

IOP was measured using a Goldmann applanation tonometer. The primary evaluation was based on the study eye (the worse eye based on the 0800 hour IOP baseline or the right eye when both eyes had the same IOP). IOP change from baseline was calculated using the baseline IOP at each time point (0800 hours at baseline to 0800 hours at Week 2, 6, and 12; 1000 hours at baseline to 1000 hours at Week 2, 6, and 12; 1600 hours at baseline to 1600 hours at Week 2, 6, and 12). Lowering elevated IOP is a treatment goal of glaucoma.
