Abstract
Purpose :
To investigate the efficacy and safety of mifepristone, a GR2-receptor antagonist, for patients with chronic and/or recurrent central serous chorioretinopathy.
Methods :
Randomized, double-masked, multi-site, placebo-controlled trial of mifepristone 300- and 900-mg daily for four weeks. Central retinal thickness (CRT) and visual acuity (BCVA) were measured throughout the study.
Results :
30 patients were randomized to placebo, 300- or 900 mg. Patients assigned to active treatment had a significant reduction in CRT (82 microns; p<0.05) and improvement in BCVA (3.6 ETDRS letters; p<0.05). Patients assigned to placebo did not have a significant change in CRT (47 microns) or BCVA (0.7 letters). Comparison of change in CRT between active- and placebo-treated patients did not reach statistical significance (p=0.15). Mifepristone was well tolerated.
Conclusions :
Oral mifepristone may reduce subretinal fluid and improve visual acuity in patients with CSC. Larger studies are warranted to extend these findings.
