COMPARISON OF VISUAL/ANATOMICAL OUTCOMES AND RECURRENCE RATE BETWEEN ORAL SPIRONOLACTONE AND PHOTODYNAMIC THERAPY FOR NONRESOLVING CENTRAL SEROUS CHORIORETINOPATHY.

PURPOSE: To compare long-term visual/anatomical outcomes and recurrence rate between oral spironolactone (SPRL) treatment and half-dose photodynamic therapy for nonresolving central serous chorioretinopathy.

METHODS

This retrospective, interventional, comparative study included 50 nonresolving central serous chorioretinopathy patients who had exhibited subretinal fluid (SRF) accumulation for >3 months. Of the 50 patients, 26 (26 eyes) received oral SPRL treatment and 24 (24 eyes) received half-dose photodynamic therapy. Best-corrected visual acuity, central subfield thickness, SRF height, and subfoveal choroidal thickness were compared between groups at 1, 2, 3, 6, and 12 months after treatment by using repeated-measures analysis of variance.

RESULTS

After treatment, best-corrected visual acuity, central subfield thickness, and SRF height significantly improved in both groups, compared with baseline. There were no significant differences in best-corrected visual acuity, central subfield thickness, or SRF height between the two groups, with the exception of 3 and 12 months of follow-up for central subfield thickness (P = 0.016 and P = 0.028, respectively) and 3 months of follow-up for SRF height (P = 0.039). However, recurrence was more likely to occur in the oral SPRL group than in the half-dose photodynamic therapy group (P = 0.002).

CONCLUSION

Oral SPRL treatment for nonresolving central serous chorioretinopathy showed good long-term visual/anatomical outcomes, compared with half-dose photodynamic therapy. However, recurrence was more likely to occur when using oral SPRL.
