The visual pathways and the ocular motor cranial nerves are frequently injured by expanding cerebral aneurysms. Neuro-ophthalmologic signs and symptoms may be the only indications of an aneurysm prior to rupture. Acute or chronic visual loss may herald an aneurysm prior to rupture. Acute or chronic visual loss may herald an aneurysm in the carotidophthalmic, supra clinoid carotid, internal carotid bifurcation, or anterior communicating artery distributions. Diplopia and retro-orbital pain may be warning signs that precede the discovery of a posterior communicating, basilar, or cavernous sinus aneurysm.
扩张性脑动脉瘤常损伤视觉通路和动眼神经。在动脉瘤破裂之前，神经眼科体征和症状可能是其唯一指征。急性或慢性视力丧失可能预示着颈动脉眼段、床突上段颈内动脉、颈内动脉分叉处或前交通动脉分布区的动脉瘤即将破裂。复视和眶后疼痛可能是后交通动脉、基底动脉或海绵窦动脉瘤被发现之前的警示信号。
