Abstract:AIM:To evaluate the safety and efficacy of dexamethasone implant in patients with non-infectious posterior uveitis withcystoid macular edema (CME).METHODS:Retrospective analysis of patients reports with CME secondary to non-infectious uveitis treated with dexamethasone implant. Data included type of posterior uveitis, any systemic immunosuppressive therapy, Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA), central macular thickness (CMT) on optical coherence tomography (OCT) and signs of intraocular inflammation at baseline and then at 2wk postoperatively and monthly thereafter. Follow-up is up to 10mo. Any per-operative and post-operative complications were recorded.RESULTS:Six eyes of 4 patients with CME due to non-infectious posterior uveitis treated with dexamethasone implant. Diagnosis included idiopathic panuveitis, birdshot chorioretinopathy and idiopathic intermediate uveitis. At baseline mean ETDRS BCVA was 63 letters and mean CMT 556 μm at 2wk postoperatively mean ETDRS BCVA improved to 70 letters and mean CMT decreased to 329 μm. All eyes showed clinical evidence of decreased inflammation. The duration of effect of the implant was 5 to 6mo and retreatment was required in 2 eyes. Two patients required antiglaucoma therapy for increased intraocular pressures.CONCLUSION: In patients with non-infectious posterior uveitis dexamethasone implant can be a short-term effective treatment option for controlling intraocular inflammation.
