NCT01923714

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.

Sampling MethodNon-Probability Sample
Study Population

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.
