Mineralocorticoid receptor antagonists in chronic central serous chorioretinopathy.

INTRODUCTION

Central serous chorioretinopathy consists of the leakage of fluid from the choroid and its accumulation into the subretinal space. Its chronic form is associated with permanent vision loss. Mineralocorticoid receptor antagonists are an alternative treatment for this condition, although there is no clear evidence about their effectiveness.

METHODS

We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach.

RESULTS AND CONCLUSIONS

We identified three systematic reviews including 22 studies overall and four of them are randomized trials. We concluded that in chronic central serous chorioretinopathy, mineralocorticoid receptor antagonists probably make little or no difference to best-corrected visual acuity. We are uncertain whether this intervention reduces subretinal fluid height because the certainty of the evidence is very low. Furthermore, this intervention may make little or no difference in terms of adverse effects, but the certainty of the evidence is low.
