Efficacy of Multiple Dexamethasone Intravitreal Implants for Refractory Retinal Vein Occlusion-Related Macular Edema and Effect of Prior Vitrectomy.

To evaluate the efficacy of dexamethasone intravitreal implants (DEX implant) in patients with treatment-resistant macular edema (ME) owing to branch and central retinal vein occlusion (BRVO/CRVO), and the influence of prior vitrectomy on this treatment. Multicenter retrospective chart review was performed on 40 CRVO and 32 BRVO eyes with persistent ME despite intravitreal anti-vascular endothelial growth factor agents and/or intravitreal triamcinolone, and/or laser therapy. Each patient received ≥1 dexamethasone 700 μg implant between March 2011 and December 2015.
