Travatan Z in Ocular Surface Health in Patients With Open-Angle Glaucoma or Ocular Hypertension

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to compare two ophthalmic solutions in patients with open-angle glaucoma or ocular hypertension.

Official Title
-----------------
An Evaluation of the Ocular Surface Health in Subjects Using TRAVATAN Z® Ophthalmic Solution Versus XALATAN® Ophthalmic Solution

Conditions
-----------------
Open-angle Glaucoma, Ocular Hypertension

Intervention / Treatment
-----------------
* Drug: Travoprost ophthalmic solution 0.004% with SofZia® preservative system (TRAVATAN Z®)
* Drug: Latanoprost ophthalmic solution 0.005% (XALATAN®)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: 18 years or older. Ocular Surface Disease Index (OSDI) score and corneal fluorescein staining score as specified in protocol. Diagnosis of open-angle glaucoma or ocular hypertension in at least one eye. Intraocular pressure (IOP) controlled with latanoprost 0.005% (XALATAN®) for at least one continuous month prior to Visit 1. Willing and able to discontinue use of any topical ocular medication other than the study medication for the duration of the study, including artificial tears. Best corrected visual acuity of -0.6 logarithm of the Minimum Angle of Resolution (logMAR) or better in each eye. Other protocol-defined inclusion criteria may apply. Exclusion Criteria: Any medical condition (systemic or ophthalmic) that may preclude safe administration of the test article. Use of contact lenses within 30 days of Visit 1. Use of contact lenses during the study. Participation in an investigational drug or device study within 30 days of entering this study. Other protocol-defined exclusion criteria may apply.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change at Day 90 From Baseline (Day 0) in Ocular Surface Disease Index (OSDI) Score | The OSDI is a 12-question validated questionnaire (resultant overall 0-100 point score) used to measure ocular symptoms, visual function and environmental factors that may affect a patient's vision, where 0 = normal and 100 = severe. The OSDI questionnaire was administered at both visits and completed by the patient with no assistance from the office staff, physician, or anyone else. The baseline OSDI score was subtracted from the 90-day OSDI score and reported as change. A negative number represents a perceived improvement in ocular health. | Baseline, Day 90 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients With Corneal Fluorescein Staining Score = 0 | The corneal surface was assessed by the investigator and graded on a scale of 0-3, where 0 = Absent (no staining present) and 3 = Severe (>50% coverage). Percentage of patients with score = 0 at 90 days was calculated by dividing the number of patients with score = 0 by the total number of patients analyzed. | Day 90 |
