Brief Summary
This study aims at validating in real-life clinical practice and using the self-reported Glaucoma Symptom Scale (GSS) questionnaire, the impact of a switch to preservative-free dorzolamide/timolol fixed combination (DTFC) in patients using preserved topical therapy for glaucoma.

Outcome Measures
Primary Outcomes (1)
Change in Glaucoma Symptom Scale questionnaire
The main study objective was to assess a change in the patient-reported Glaucoma Symptom Scale questionnaire, filled in at baseline (Week 0) and at the end of the 8 week of therapy with preservative-free DTFC.
8 weeks
Secondary Outcomes (2)
Change in Functional-related items of the Glaucoma Symptom Scale
8 weeks
Change in Symptom-related items of the Glaucoma Symptom Scale
8 weeks
Study Arms (1)
Glaucoma
Patients with open-angle glaucoma (OAG) that require topical intraocular pressure lowering therapy and that were scheduled to switch current therapy to preservative-free DTFC.
Eligibility Criteria
Patients with OAG that require topical therapy for intraocular pressure lowering and that were scheduled to switch current therapy to preservative-free DTFC
You may qualify if:
- Diagnosed as having OAG in one or both eyes
- Who have used the previous preserved eye drops treatment for at least 4 weeks in one eye or both eyes
- Experiencing pre-established ocular surface disease symptoms, as defined in the 2007 report of the International Dry Eye Workshop
- Accepting to participate in the study and who has provided a written informed consent
You may not qualify if:
- Who have already been treated with preservative-free DTFC
- Whose visual acuity is importantly impaired by a severe ocular disease other than OAG, as assessed by the physician
- Currently involved in a clinical trial or study cohort or pharmaco-epidemiology study or interventional study
- With serious mental or physical disability which could interfere with a patient-reported assessment
- Pregnant women.
