Carotid-ophthalmic aneurysms, though comprising only 4% of cerebral aneurysms, can lead to progressive visual deterioration by compressing the visual pathways, and early intervention is essential to prevent permanent vision loss. When suspected, urgent angiographic imaging should be requested. This report highlights an uncommon but treatable cause of progressive visual impairment due to optic nerve compression by a carotid aneurysm.
