Retinal Artery Occlusion after Embolization of Intracranial Tumor

Embolization plays an important role as an adjunct to the surgical management of tumors. The use of liquid embolic agents, embolic microparticles or coils to devascularize the tumor bed facilitates safer surgical resection of the tumor itself [1]. However, this procedure carries the risk of neurological deficit, visual loss and severe disability. Branch retinal artery occlusion [2] and cilioretinal artery occlusion [3] have been reported following embolization of intracranial meningioma. Here, we report two cases of iatrogenic retinal artery occlusions occurring after embolization of intracranial tumor feeder arteries with occlusive agents. Retinal artery occlusion is an ocular emergency that is associated with profound morbidity.
