  Purpose
This study will evaluate the safety and efficacy of brimonidine tartrate/timolol fixed combination (Combigan®) compared with brimonidine tartrate (Alphagan®) and timolol in patients with glaucoma or ocular hypertension who do not respond well to topical beta blockers.

Condition Intervention
Glaucoma Ocular Hypertension Drug: brimonidine tartrate/timolol fixed combination ophthalmic solution Drug: brimonidine tartrate ophthalmic solution Drug: timolol ophthalmic solution Other: fixed combination vehicle

Primary Outcome Measures:
  • Change From Baseline in Mean Diurnal Intraocular Pressure (IOP) in the Study Eye at Week 4 [ Time Frame: Baseline, Week 4 ]
    Intraocular pressure (IOP) was measured in the study eye at baseline and Week 4. IOP is a measurement of the fluid pressure inside the eye. A negative number change from baseline indicates a reduction in IOP (improvement).


Enrollment: 238
Study Start Date: October 2010
