Efficacy and Safety Study of Brinzolamide 1%/Brimonidine 0.2% vs. Brinzolamide 1% and Brimonidine 0.2%

This study consisted of 6 visits conducted during 2 sequential phases: the Screening/Eligibility phase, which included a screening visit and 2 eligibility visits, and the Treatment phase, which included 3 on-therapy visits conducted at Week 2, Week 6, and Month 3. A washout period based on previous ocular medication preceded Eligibility Visit 1. Patients who met all inclusion/exclusion criteria at both eligibility visits were randomized (1:1:1) to receive treatment with 1 of 3 study drugs for 3 months. Study drug instillation began the morning after the second eligibility visit.
