Abstract:
Interference with visual pathways is usually not caused by intracranial aneurysms. Aneurysms of the anterior communicating artery rarely produce visual symptoms and signs in spite of their proximity to the visual pathways. The reason may be that these aneurysms rupture and present with subarachnoid hemorrhage before becoming large enough to exert significant pressure on the chiasm or optic nerves. The visual symptoms would be presented as visual field defect or impaired vision. These can be explained as the result of direct compression of the optic pathways, ischemic changes in the visual pathways caused by severe vasospasm after subarachnoid hemorrhage, or intraocular pathology such as retinal hemorrhage. 2 cases of anterior communicating artery aneurysms associated with visual symptoms are presented with a brief review of literatures.
