Central retinal artery occlusion in association with an aneurysm of the internal carotid artery.

Abstract

To report an unusual case of central retinal artery occlusion in a 41-year-old woman. Interventional case report. A 41-year-old woman presented with sudden and painless decrease of visual acuity of the left eye. Indirect ophthalmoscopy revealed the typical fundus findings of a central retinal artery occlusion. The fovea was spared by a cilioretinal arteriole. Cerebral angiography showed an aneurysm of the left internal carotid artery, measuring approximately 1.7 x 1.5 x 1.7 cm. The aneurysm was located in close proximity to the ophthalmic branch. Aneurysm of the intracranial arteries should be included in the differential diagnosis of central retinal artery occlusion in young patients.
