PURPOSE: To evaluate the safety and efficacy of Ozurdex (dexamethasone intravitreal implant) 0.7 mg in the treatment of uveitic macular edema in vitrectomized eyes. METHODS: Data from 13 patients (17 eyes) with persistent uveitic cystoid macular edema and a history of pars plana vitrectomy in the study eyes that were treated with intravitreal injection of 0.7-mg dexamethasone implant were reviewed retrospectively. Main outcome measures were changes in central retinal thickness measured by optical coherence tomography and changes in best-corrected visual acuity. RESULTS: The median age of patients was 61 years (range, 19-81 years). The median duration of uveitic macular edema was 12 months (range, 2-72 months). The mean baseline central retinal thickness (95% confidence interval) was 461.6 μm (403.8-519.4), decreased to 277.2 μm (244.6-309.8) at 4 weeks (P < 0.01), remained low at 349.9 μm (281.8-418.0) at 3 months (P = 0.01), and then reached 394.1 μm (328.3-459.8) at 6 months (P = 0.14). After 3 months, there was a median improvement of 2 lines of best-corrected visual acuity, with 52.9% of eyes gaining 2 lines or more (P < 0.01). At 6 months, there were 5 eyes that maintained the 2 lines gain and none had lost >1 line from baseline (P = 0.03). In 8 eyes (47.1%), reinjection of the implant was performed at a mean of 6.5 months. Ocular hypertension (47.1%), hypotony (11.8%), anterior chamber displacement of the implant (5.9%), and glaucoma, which required filtration surgery (5.9%), were the most common adverse events. Mean follow-up was 9.6 months (range, 6-17 months). CONCLUSION: In this small case series of eyes with limited follow-up, treatment with dexamethasone intravitreal implant injection for uveitic macular edema in vitrectomized eyes was associated with favorable visual outcomes and had an acceptable safety profile.
