Central Serous Chorioretinopathy
Conditions
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.
Interventions
Topical brinzolamide given bd for 3 months

Eligibility
Inclusion criteria
* Central serous chorioretinopathy (CSC) affecting the fovea, non-resolving after 4 months of follow-up * Optical coherence tomography (OCT) shows foveal subretinal fluid * Fluorescein angiography and indocyanine green confirm the diagnosis
Exclusion criteria
* Any other ophthalmic condition that may lead to subretinal fluid * Choroidal neovascularization * Myopia \> -6D * Previous treatment for CSC in the past 6 months * Known allergy to fluorescein or indocyanin green * Known allergy for brinzolamide * Pregnancy, breast feeding
