Patient Preference Comparison of AZARGA Versus COSOPT in Patients With Glaucoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess patient preference of AZARGA® compared to COSOPT® after a single drop of each medication is administered to both eyes, in patients with open-angled glaucoma or ocular hypertension.

Official Title
-----------------
Patient Preference Comparison of AZARGA Versus COSOPT After Single Doses in Patients With Open-Angled Glaucoma or Ocular Hypertension

Conditions
-----------------
Glaucoma

Intervention / Treatment
-----------------
* Drug: Brinzolamide/Timolol Maleate Fixed Combination (AZARGA)
* Drug: Dorzolamide/timolol Maleate Fixed Combination (COSOPT)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Clinical diagnosis of ocular hypertension, primary open-angle or pigment dispersion glaucoma in both eyes. On a stable regimen intraocular pressure (IOP) lowering medication within 30 days of screening visit. IOP considered to be safe (in the opinion of the investigator) in both eyes in such a way that should assure clinical stability of vision and the optic nerve throughout the study period. Willing to discontinue use of all other ocular drugs (prescribed and over-the-counter) prior to receiving the screening dose during Screening Visit and for the course of the study. Other protocol-defined inclusion criteria may apply. Exclusion Criteria: Known medical history of allergy, hypersensitivity, or poor tolerance to any component of the preparations to be used in this study that is deemed clinical significant in the opinion of the Principal Investigator. Corneal dystrophies in either eye. Risk of visual field or visual acuity worsening as a consequence of participating in this study, in the investigator's best judgment. Bronchial asthma or a history of bronchial asthma, or severe chronic obstructive pulmonary disease that would preclude the safe administration of a topical beta-blocker. History of severe allergic rhinitis. Participation in any other investigational study within 30 days prior to the Screening/Baseline Visit. Other protocol-defined exclusion criteria may apply.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Discomfort | One drop of medication will be instilled in each eye. At one minute after instillation, subject will be given an Ocular Discomfort Scale and will record ocular discomfort on a questionnaire using a 10-point scale, with 0 being no discomfort and 09 being substantial discomfort. | One minute after instillation |
