鼻侧视野异常最常见于视网膜和前部视神经病变。视路的颅内病变引起鼻侧视野丧失是罕见的。作者报告5例这种病例的结果分析。神经外科病人鼻侧视野丧失常由于慢性萎缩性视乳头水肿所致。长久以来硬化而扩张的颈内动脉一直被认为是视神经萎缩和鼻侧视野缺损的原因,而视神经损害的发生率和病理生理学仍未确定。视神经被邻近动脉所压的深沟并不一定引 Nasal visual field abnormalities are most common in retinal and anterior optic neuropathy. Vision-related intracranial lesions cause loss of nasal vision is rare. The authors report results of 5 cases of this case analysis. The loss of nasal vision in neurosurgical patients is often due to chronic atrophic papilledema. Hardened and dilated internal carotid arteries have long been considered as the cause of optic nerve atrophy and nasal visual field defects, and the incidence and pathophysiology of optic nerve damage have not been determined. The deep groove where the optic nerve is pressed by the adjacent artery does not necessarily lead
