Topical Dexamethasone as an Adjuvant to Mineralocorticoid Receptor Antagonists for the Treatment of Recalcitrant Central Serous Chorioretinopathy.

ABSTRACT

BACKGROUND AND OBJECTIVE: A previous report demonstrated efficacy of mineralocorticoid antagonist with adjuvant topical dexamethasone (MRA+DEX) in resolving subretinal fluid (SRF) in a chronic central serous chorioretinopathy (CSCR) patient. This pilot study investigates the use of MRA+DEX to treat recalcitrant, chronic CSCR patients. STUDY DESIGN: Retrospective review of chronic, recalcitrant CSCR patients unresponsive to MRA alone who were treated with MRA+DEX and followed for up to 3 months. Apical SRF thickness and visual acuity were measured. RESULTS: Ten eyes of eight chronic, recalcitrant patients were included with an average follow-up of 109 days. Mean percent reduction in apical fluid thickness at one month and at last follow-up after adding dexamethasone (DEX) was 33% and 52%, respectively. Five eyes (50%) achieved complete resolution of SRF. Three eyes (30%) showed partial response and two (20%) eyes had no response. There was no significant change in visual acuity. CONCLUSIONS: MRA+DEX decreased SRF in some recalcitrant, chronic CSCR patients. Large prospective studies are needed to evaluate the utility of MRA+DEX in these chronic CSCR patients.
