Purpose:To report a case in which a prophylactic embolization of a feeder artery to an intarcranial meningioma led to an occlusion of a cilioretinal artery.Design:A case report.Methods:A 48-year-old man with an intracranial meningioma presented with ocular pain and visual loss in his right eye following embolization of a feeder artery to the meningioma with polyvinyl alcohol.Results:Ophthalmoscopy 1 month later showed a cilioretinal artery occlusion which was confirmed by fluorescein angiography.His visual acuity was 0.01 in the right eye.The patient was not treated for his ocular symptoms,and his visual acuity 9 month postoperatively improved slightly to 0.1.Conclusions:Our case demonstrated that an occlusion of a retinal artery can be a complication of preoperative embolization of an artery to an intracranial tumor and can lead to severe visual loss.
