Treatment of central serous chorioretinopathy with mineralocorticoid receptor antagonists

Abstract

Over 3years have passed since the last publication on the therapeutic principle "Mineralocorticoid receptor antagonists as treatment option for acute and chronic central serous chorioretinopathy" by Maier etal., and numerous new studies have been published on the topic. The aim of this work is to provide an update on the current literature and reevaluate the role of mineralocorticoid receptor antagonists in the treatment of central serous chorioretinopathy (CSC). Acomputer-based literature search in PubMed yielded atotal of 20relevant articles published from 2013 to 2017, which were evaluated in terms of the effect of mineralocorticoid receptor antagonists in CSC treatment. Due to study protocol variability with different primary endpoints and follow-up periods, an in-depth comparison of the selected studies could not be performed. Moreover, the small study populations further limit their validity in this per se heterogeneous disease spectrum. Despite these limitations, current data indicate that aldosterone antagonists are effective in decreasing subretinal fluid and improving visual acuity in patients with CSC. The selective aldosterone antagonist eplerenone with alow side effect profile is atreatment option in patients with non-resolving CSC. Prospective, randomized studies with uniform disease definition and study criteria are necessary to validate the therapeutic effect and to determine the ideal time of intervention and treatment duration.
