Safety and Efficacy of Intravitreal Dexamethasone Implant for Refractory Uveitic Macular Edema in Adults and Children

ABSTRACTPurpose: 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 depende...
