Long-Term Real-Life Efficacy and Safety of Repeated Ozurdex® Injections and Factors Associated with Macular Edema Resolution after Retinal Vein Occlusion: The REMIDO 2 Study

Purpose: The objective was to study long-term real-life efficacy and safety of repeated Ozurdex (R) injections and factors associated with macular edema (ME) resolution after retinal vein occlusion. Methods: Patients with ME after retinal vein occlusion, receiving Ozurdex (R), were included to assess the following endpoints: visual acuity and central retinal thickness, retreatment, number of injections, side effects and ME resolution. ME resolution was defined as permanent discontinuation of intravitreal injections (IVTs) for at least 6 months after the last IVT. Results: A total of 94 eyes were included with an average of 2.6 IVTs (max 6 IVTs). 58.6% of patients gained letters and 51.1% of patients showed ME resolution. Among the resolved patients, 64.6% were treatment na ve, 60.4% had branch retinal vein occlusion, and 78.1% gained >= 15 letters. Conclusions: Ozurdex seemed to be a valuable treatment which may allow to achieve long-term anatomical and functional improvements and ME resolution with a minimum number of IVTs. (C) 2016 S.
