Difluprednate for the treatment of uveitic cystoid macular edema

Abstract

Purpose To describe clinical outcomes associated with the use of topical difluprednate in treating uveitic cystoid macular edema. Design Retrospective, interventional case series. Methods Setting: Medical record review in a tertiary care uveitis center. Patient Population: Fifty-eight patients (72 eyes) with uveitic cystoid macular edema (CME) treated with difluprednate 0.05% ophthalmic solution between June 2012 and May 2016. Main Outcome Measures: Macular central subfield thickness (CST) determined by optical coherence tomography, improvement of CME (≥20% reduction in CST or resolution), and resolution of CME (CST ≤ 320 μm with no cysts) at 30 days after starting treatment. Outcomes were assessed up to 90 days. Results CST on average decreased by 17% (95% CI: −33%, −7%) for eyes using only difluprednate (n = 43) and by 6% (95% CI: −17%, −2%) for eyes in patients using concomitant systemic immunosuppressive therapy (n = 29) at 30 days, a 12% difference between groups (95% CI: 2%, 21%, P = .02). Of eyes on difluprednate alone, 76% had improvement and 48% had resolution of CME. In patients using systemic therapy, 37% of eyes had improvement and 17% had resolution. Eight eyes (11%) had an intraocular pressure (IOP) > 24 mm Hg within the first 30 days. By 90 days, CME had improved in 69% of all eyes and resolved in 43% of eyes, with only 9 patients starting or increasing systemic immunosuppressive medications and 2 patients receiving periocular corticosteroid injections. Conclusions Difluprednate was associated with an improvement in uveitic CME and could be a reasonable first-line therapy. IOP should be closely monitored.
