title: Resolution of Persistent Cystoid Macular Edema due to Central Retinal Vein Occlusion in a Vitrectomized Eye following Intravitreal Implant of Dexamethasone 0.7 mg.
abstract: We report the case of a 62-year-old woman with a history of vitreoretinal surgery for vitreous hemorrhage secondary to central retinal vein occlusion (CRVO). Because of the persistence of macular edema (ME), she received 2 intravitreal injections of bevacizumab 0.5 mg (Avastin®, Genentech/Roche) three months after vitrectomy, without functional or anatomical improvement. Six months after vitrectomy, she therefore received an intravitreal implant of dexamethasone 0.7 mg (Ozurdex®). An improvement in her best-corrected visual acuity and central macular thickness, as measured by optical coherence tomography, was detected 7 days after the injection, and complete resolution of the ME and retinal hemorrhages was observed 6 months after the injection. Dexamethasone intravitreal implant might be an effective treatment option in ME secondary to CRVO, also in vitrectomized eyes.
