Brief summary: The purpose of this study was to evaluate the efficacy and safety of a fixed combination of Brinzolamide/Brimonidine in lowering intraocular pressure (IOP) relative to each of its individual active components in patients with open-angle glaucoma and/or ocular hypertension.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Sign Informed Consent document.
* Diagnosis of open-angle glaucoma or ocular hypertension, with mean intraocular pressure within protocol-specified range at eligibility visit/s.
* Other protocol-specified inclusion criteria may apply.

Exclusion Criteria:

* Females of childbearing potential if pregnant, lactating, or not using highly effective birth control measures.
* Any form of glaucoma other than open-angle glaucoma.
* Severe central vision loss in either eye.
* Chronic, recurrent, or severe inflammatory eye disease.
* Ocular trauma within the preceding 6 months.
* Ocular infection or ocular inflammation within the preceding 3 months.
* Clinically significant or progressive retinal disease such as retinal degeneration, diabetic retinopathy, or retinal detachment.
* Best-corrected visual acuity score worse than 55 letters using the Early Treatment Diabetic Retinopathy Study chart.
* Other ocular pathology (including severe dry eye) that may, in the opinion of the Investigator, preclude the administration of study product.
* Ocular surgery within the preceding 6 months.
* Ocular laser surgery within the preceding 3 months.
* Any abnormality preventing reliable applanation tonometry.
* Any other conditions, including severe illness, which could make the patient, in the opinion of the Investigator, unsuitable for the study.
* Other protocol-specified exclusion criteria may apply.
