About this trial
This is an interventional treatment trial for Glaucoma focused on measuring Glaucoma
Eligibility Criteria
Inclusion Criteria:
- Unilateral or bilateral primary open angle glaucoma, ocular hypertension or pseudoexfoliation syndrome.
- Intraocular pressure greater than 18 mmHg (mean diurnal) and less than 32 mmHg.
- Other protocol-defined inclusion criteria applied.
Exclusion:
- Previous intraocular surgery, except uncomplicated clear cornea phacoemulsification or argon laser trabeculoplasty.
- Argon laser trabeculoplasty or phacoemulsification within the last 3 months.
- Central corneal thickness outside the 500 - 600 (inclusive) micron range as measured by ultrasonic pachymetry.
- Ocular or periocular inflammation within 3 months prior to study (except blepharitis related or seasonal allergic conjunctivitis).
- History of uveitis or previous intraocular inflammation (other than post-operatively).
- Hypersensitivity to sulfa, or benzalkonium chloride.
- History of use of any steroids for over 1 week within 3 months of screening or likely need for any corticosteroids during the study (except inhaled, nasal or topical non-ocular).
- Other protocol-defined exclusion criteria applied.

Arm Label
Xalatan + Azopt
Xalatan + Placebo
Arm Description
Xalatan dosed once a day at 10 pm, with Azopt dosed three times a day at 8 AM, 2 PM, and 10:05 PM as an adjunctive therapy for 3 months.
Xalatan dosed once a day at 10 pm, with placebo dosed three times a day at 8 AM, 2 PM, and 10:05 PM concomitantly for 3 months.
Outcomes
Primary Outcome Measures
Mean Change From Baseline in Intraocular Pressure, 8 AM, at 3 Months
Intraocular pressure was measured by Goldmann applanation tonometry. A negative number indicated a reduction in intraocular pressure.
Mean Change From Baseline in Intraocular Pressure, 12 PM, at 3 Months
Intraocular pressure was measured by Goldmann applanation tonometry. A negative number indicated a reduction in intraocular pressure.
Mean Change From Baseline in Intraocular Pressure, 4 PM, at 3 Months
Intraocular pressure was measured by Goldmann applanation tonometry. A negative number indicated a reduction in intraocular pressure.
Mean Change From Baseline in Intraocular Pressure, Diurnal, at 3 Months
Diurnal intraocular pressure is the mean of the three timepoints measured (8AM, 12PM & 4PM). Intraocular pressure was measured by Goldmann applanation tonometry. A negative number indicated a reduction in mean intraocular pressure.
