Abstract
Purpose :
To report the outcomes of patients with chronic central serous chorioretinopathy (cCSCR) treated with mineralocorticoid-receptor (MR) antagonists after 24 months of follow-up.
Methods :
Nineteen eyes of 17 patients with non-resolving cCSCR were treated with oral MR antagonists, either eplerenone or spironolactone. Best-corrected visual acuity (BCVA) and anatomical parameters including central macular thickness, subretinal fluid (SRF) height at the fovea, and sub-foveal choroidal thickness (SFCT) were measured during 24 months following initiation of treatment, and were compared with baseline values using the Wilcoxon test.
Results :
Thirteen patients (78%) were male and 4 (22%) were female. The mean age at presentation was 53±11 years. The mean duration of subretinal detachment affecting the fovea was 8.9±4.9 months before initiation of treatment. The mean duration of treatment was 22.1±8 months. Logarithm of the minimum angle of resolution (LogMAR) BCVA was 0.21 at baseline, 0.19 at 6 months (p=0.39), 0.15 at 12 months (p=0.086) and 0.17 at 24 months (p=0.25). The central macular thickness (CMT) was 320±67 µm at baseline, 270±36 µm at 6 months (p=0.0007), 276±47 µm (p=0.017) at 12 months and 259±42.8 µm at 24 months (p=0.0002). Foveal SRF was 95 ± 71 µm at baseline, 41±49 µm at 6 months (p=0.02), 51±58 µm at 12 months (p=0.052), and 25±35 µm at 24 months (p=0.004). Mean subfoveal choroidal thickness was 439±105 µm at baseline, 422±104 µm at 6 months (p=0.15), 376±91 µm at 12 months (p=0.019) and 392±99 µm at 24 months (p=0.046).
Conclusions :
Oral MR antagonists had a favorable long-term anatomical effect in chronic, recalcitrant central serous chorioretinopathy. The decrease in choroidal thickness supported the involvement of the MR in CSCR pathogenesis. The treatment also led to a moderate visual improvement that remained non-significant due to the small study population. Results from prospective randomized studies are needed to confirm these encouraging observations.
