A Case of Superior Visual Field Defect following Rupture of an Anterior Communicating Artery AneurysmSuperiore Gesichtsfelddefekte nach Ruptur eines anterioren kommunizierenden Aortenaneurysmas
Anterior communicating artery (ACA) aneurysm is the most common type of intracranial aneurysm, accounting for about 30% of all cerebral aneurysms . Causes of visual deterioration and visual field defects induced by an intracranial aneurysm can generally be classified into optic nerve compression by the aneurysm, Terson syndrome, direct encephalopathy due to bleeding and hematoma from the ruptured aneurysm, and ischemia of the optic nerve due to vasospasm. Development of a superior altitudinal visual field defect after rupture of an ACA aneurysm seems to be extremely rare and is presumably due to ischemic optic neuropathy caused by vasospasm after subarachnoid hemorrhage (SAH) , , .
Here, we report a case of superior altitudinal visual field defect and optic disc atrophy associated with SAH following rupture of an ACA aneurysm.
