Abstract
PURPOSE: To assess safety and efficacy of intravitreal dexamethasone (DEX) implant in refractory uveitic macular edema (ME). METHODS: We retrospectively analyzed medical records of patients with nonresponsive ME secondary to chronic, noninfectious intermediate or posterior uveitis, treated with intravitreal DEX implants. RESULTS: A total of 42 eyes of 34 patients (aged 6-67 years) received 56 implants. Mean follow-up was 19.2 ± 2.2 months after DEX implant. The mean visual acuity (0.48 ± 0.06 logMAR to 0.34 ± 0.1 logMAR) and mean central retinal thickness (472.2 ± 35 to 274.7 ± 60.6 µm) improved considerably before and after DEX implant. A total of 11 eyes needed repeat implants after a prolonged time to recurrence (12.6-20.9 months). A total of 10 eyes needed no additional treatment. Oral steroids could be stopped in 40% patients. Intraocular pressure increased in seven and cataract progressed in six eyes. CONCLUSION: Intravitreal DEX implant is safe and effective adjunct therapy. It reduces dependence on systemic steroids, immunosuppressives and provides long-term effects.
