Study of Brimonidine and Timolol Ophthalmic Solution With Latanoprost Compared With Latanoprost in Glaucoma Patients

This study will evaluate the safety and efficacy of patients switched from latanoprost monotherapy to a combination therapy of latanoprost with COMBIGAN® (brimonidine 0.2%/timolol 0.5% fixed combination ophthalmic solution) for chronic angle closure glaucoma.

Inclusion Criteria:

• Patient has been administering latanoprost eye drops in affected eye(s) for at least 12 weeks prior to study
• Patient must have at least partially responded to latanoprost and requiring further IOP lowering eye drops
• Diagnosis of chronic angle-closure glaucoma
• Patients using COMBIGAN® in the past must not have been discontinued due to adverse events or lack of efficacy.

Exclusion Criteria:

• Known allergy or hypersensitivity to COMBIGAN®
• Corneal abnormalities that would preclude accurate IOP readings
• Any other active ocular disease other than glaucoma or ocular hypertension
• Ocular surgery within the past 3 months.
