title: Iatrogenic central retinal artery occlusion after carotid body tumor embolization and excision.
abstract: Objective:To report a case of iatrogenic central retinal artery occlusion after embolization and surgical resection of carotid body paraganglioma.Methods:Case reportResults:One adult female patient presented with persistent unilateral visual loss after embolization with Embosphere®and Contour®microparticles of carotid body tumor. Fluorescein angiography revealed intraluminal microspheres in the central retinal artery ramifications. OCT revealed intraretinal spherical, hyporeflective particles with posterior shadowing.Conclusions:Central retinal artery occlusion should be assessed as a possible complication after surgical repair of head and neck paragangliomas.
