Eplerenone for treatment of chronic central serous chorioretinopathy.

PURPOSE

To assess the morphological and functional outcome of oral eplerenone for treatment of patients with chronic central serous chorioretinopathy (CSC) in a real life experience.

PATIENTS AND METHODS

In this retrospective study, we reviewed the clinical files of 30 patients with chronic CSC. All patients were treated with eplerenone for a period of 6 weeks or 3 months depending on the clinical response. Main outcome measures included: best corrected visual acuity (BCVA), central macular thickness (CMT) and height of the subretinal fluid (SRF). Comparisons between responders and non-responders were performed to identify factors that were predictive of the treatment response.

RESULTS

All patients were treated with eplerenone 18 ± 20 weeks after onset of the first symptoms. BCVA (LogMAR) improved from 0.2 ± 0.2 to 0.13 ± 0.18 at 6 weeks ( = 0.01) and to 0.09 ± 0.15 at 3 months ( = 0.01). Mean CMT decreased from 409 ± 136 to 323 ± 87 µm at 6 weeks ( = 0.001) and to 298 ± 98 µm at 3 months ( = 0.01). Mean height of SRF decreased from 153 ± 126 to 73 ± 79 µm at 6 weeks ( = 0.001) and to 49 ± 88 µm at 3 months ( = 0.005). Complete resolution of SRF was achieved in 20 patients after 3 months (67%). Reported stress in the medical history was the only statistical significant predictive factor associated with a positive treatment response.

CONCLUSION

This study showed a statistically significant improvement of the best corrected visual acuity and a significant reduction of macular thickness and subretinal fluid in patients with chronic CSC treated with oral eplerenone, especially in patients under stress.
