  Purpose
Local therapy for glaucoma is known to induce a conjunctival inflammation. Because of this, trabeculectomy is more likely to fail. The investigators exchange the local therapy by systemic therapy using acetazolamide and measure the eye pressure using local therapy and systemic therapy using acetazolamide. The investigators suspect an elevated eye pressure using acetazolamide compared to local therapy. In summary acetazolamide could be a better choice in reference to conjunctival inflammation, but a worse choice in reference to controlling eye pressure.

Condition Intervention
Control of Elevated Eye Pressure by Local and Systemic Therapy Drug: Acetazolamide for glaucoma patients to lower eye pressure

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Comparing Eye Pressure Using Maximal Tolerated Local Therapy or Systemic Acetazolamide. A Possible Pretreatment for Trabeculectomy Surgery.

Primary Outcome Measures:
  • Eye pressure [ Time Frame: Once at the beginning of the study and once 3 to 4 weeks later ]
    The eye pressure is measured at the beginning of the study, when the patient is using the maximal tolerated local therapy and 3 to 4 weeks later, when using systemic acetazolamide treatment.


Study Start Date: February 2009

Groups/Cohorts Assigned Interventions
Patient with a trabeculectomy planed Drug: Acetazolamide for glaucoma patients to lower eye pressure
Acetazolamide tablets 3 times daily for 3 to 4 weeks
