Brinzolamide for the Treatment of Chronic Central Serous Chorioretinopathy

Phase 2
Conditions
Central Serous Chorioretinopathy
Interventions
Registration Number
NCT03542006
Lead Sponsor
Tel-Aviv Sourasky Medical Center
Brief Summary

Examine the efficacy of brinzolamide for the treatment of central serous chorioretinopathy

Detailed Description

Brinzolamide is a carbonic anhydrase inhibitor. Previously, carbonic anhydrase inhibitors have been shown to be effective for the treatment of macular edema when administered orally, also for central serous chorioretinopathy. However, this treatment carries the risk of severe side effects.

The goal of this study is to examine the efficacy of the topical form of treatment of carbonic anhydrase inhibitors in patients with chronic, non-resolving, central serous chorioretinopathy.
