Abstract

Aims To evaluate the long-term oral mineralocorticoid receptor antagonist (MRa) treatment in chronic central serous chorioretinopathy (CSC).

Methods Patients with chronic non-resolving CSC (defined as foveal subretinal fluid (SRF) lasting >4 months with retinal pigment epithelium (RPE) alterations) treated with MRa only (eplerenone or spironolactone) for at least 6 months were retrospectively included. Clinical and imaging characteristics were recorded during visits at baseline, 6, 12, 18 and 24  months.

Results Sixteen eyes of 16 patients were included (mean age 53±11 years; 14 men, 2 women). Mean duration of SRF before treatment initiation was 11.2±19.7 months. MRa treatment was administered during 21.0±5.1 months (range, 10–24 months). There was a progressive improvement of visual acuity (p=0.05), a decrease of foveal SRF height (p=0.011), central macular thickness (p=0.004) and subfoveal choroidal thickness (p=0.002) over 24  months. Changes in SRF were correlated with subfoveal choroidal thickness at 24 months (p=0.006, Spearman r=065). The mean time to complete foveal SRF resolution was 10.5±8.0 months after treatment initiation. At 24 months, foveal SRF resolution was achieved in 13 eyes (81%). Minor side effects occurred in five patients (31%) and resolved after switching between MRa.

Conclusion The visual and anatomical benefit of MRa treatment prolonged for 6 months or more in chronic, non-resolving CSC appeared to be maintained over a 24-month period. These results suggest that MRa can be proposed as an alternative therapy in severe CSC with advanced RPE alterations.
