Brief Summary:
To compare Combigan Two Times Daily (BID) vs Simbrinza Three Times Daily (TID) in subjects currently being treated with Latanoprost for Open-Angle Glaucoma or Ocular Hypertension. Both of these drugs are currently FDA approved as combination therapy for patients with Open-Angle Glaucoma or Ocular Hypertension. The purpose of this clinical trial would be to assess which treatment, if either, is superior in lowering intraocular pressure (IOP). A secondary objective is to assess the tolerability of each drug.

Primary Outcome Measures :
  1. Intraocular Pressure [ Time Frame: Day 0 (08:00, 10:00 16:00), Day 30 (08:00, 10:00, 16:00), Day 90 (08:00, 10:00,16:00) ]
    The Intraocular Pressure will be assessed on study subjects. IOP (Intraocular Pressure) will be measured using a Goldmann applanation tonometer. Both eyes will be tested, with the right eye preceding the left eye. The operator will initially set the dial at 10 mmHg, then look through the slit lamp and adjust the dial to take the reading, and then record the results. The procedure will be repeated on the same eye twice consecutively. If the measurements are within 2mmHg or less of each other, the mean of the 2 reading will be reported as the IOP at that time point. If the 2 reading are more than 2mmHg apart from each other, a third (consecutive) reading will be taken and the median (middle) IOP will be reported as the IOP at that time point. Preferable, the same operator will measure IOP and the same tonometer will be used at each visit.

Secondary Outcome Measures :
  1. Ocular Symptom and Tolerability Questionaire [ Time Frame: Baseline (Day 0), Visit 2 (Day 7), Visit 3 (Day 30), Visit 4 (Day 90) ]
    The secondary endpoint of this study was to determine the tolerability of each treatment group by utilizing ocular symptom questionnaires administered at each study visit. These questionnaires assessed Oral effects (bad taste, dry mouth) and Ocular comfort effects (itching, burning, stinging, burning on instillation, blurred vision). The scale proved was none=0, mild=1, moderate=2, severe=3.
