Iatrogenic Vitreous Hemorrhage, Subretinal Hemorrhage, and Branch Retinal Vein Occlusion after YAG Laser Vitreolysis for Symptomatic Vitreous Floaters

A 63-year-old woman was referred for a new vitreous hemorrhage in the right eye after YAG laser vitreolysis for symptomatic floaters by an outside provider. At presentation her visual acuity was hand motion. B-scan ultrasonography demonstrated vitreous hemorrhage and a possible chorioretinal disruption. The following week the patient underwent a vitrectomy to remove the vitreous hemorrhage. A partially clotted subretinal hemorrhage and multiple hemorrhages extending from the inferotemporal arcade were noted (Fig A). One week later, vision improved to 20/80. OCT demonstrated macular edema (Fig B). Fluorescein angiography revealed delayed arteriovenous filling and late leakage of the inferior arcade consistent with a branch retinal vein occlusion (Fig C-D) (Magnified version of Fig A-D is available online at www.aaojournal.org).
