Visual Field Defects Following an Uncomplicated Coil Embolisation of a Carotid-Ophthalmic Aneurysm

Abstract

A carotid-ophthalmic aneurysm often causes ocular symptoms and signs not only because of subarachnoid haemorrhage due to ruptured aneurysm but also because of the anatomical location, a proximity to the optic apparatus and ophthalmic artery. In addition, the permanent vision loss may be developed by direct injury to optic nerve and ophthalmic artery after surgical treatment. Recently, endovascular treatments such as coil embolisation have been frequently used for this aneurysm with a decreased complication. However, coil embolisation may rarely cause acute and delayed visual deterioration due to thromboembolism and perianeurysmal inflammation. The authors report two patients who early or immediately developed visual field defects following an uncomplicated coil embolisation of a carotid-ophthalmic aneurysm.
