PURPOSE: To determine the effect of an adrenocorticoid antagonist (ketoconazole) in the treatment of patients with central serous chorioretinopathy (CSC). METHODS: Ketoconazole was given at an oral dose of 600 mg per day for 4 weeks. Laboratory monitoring included 24-hour urinary cortisol and liver function tests at baseline, 4 weeks, and 8 weeks. Changes in greatest linear dimension were followed with fluorescein angiography at baseline, 4 weeks, and 8 weeks. Posterior pole anatomy was assessed with optical coherence tomography at baseline, 4 weeks, and 8 weeks. Ophthalmic examination and best-corrected visual acuity were assessed at each interval visit. RESULTS: Median visual acuity in the study eye remained stable at 20/40 throughout the 8-week follow-up. Median lesion height and greatest linear dimension were stable at 4 weeks and decreased at 8 weeks. CONCLUSION: Ketoconazole lowered endogenous cortisol after 4 weeks of 600 mg daily. While median visual acuity, lesion height, and greatest linear dimension remained unchanged during the month of drug treatment, there may have been a delayed therapeutic response seen at 8 weeks.
