Background: Retinal artery occlusion can lead to sudden visual loss without pain. The acute management of retinal artery occlusion remains unresolved.
Case Report: A 65-year-old male was hospitalized to an emergency room for visual loss on the left side within 6 hours of onset. Combined occlusion at retinal artery and ciliary artery was confirmed by an ophthalmologist and we assessed ophthalmic artery occlusion. However, MRA revealed no significant steno-occlusion of internal carotid artery. Transfemoral cerebral angiography was carried out immediately and showed a movable thrombus at the orifice of the ophthalmic artery. We decided on endovascular thrombectomy to prevent permanent visual loss. Finally, his visual acuity was improved after successful thrombectomy.
Conclusions: Although MRA is intact, small thrombus right at the orifice of the ophthalmic artery can cause a sudden monocular visual loss due to occlusion of the retinal artery. In this setting, urgent endovascular thrombectomy can offer visual improvement.
