To report a case of a developmental anatomic finding of the ophthalmic artery (OA) in a patient with ipsilateral progressive advanced glaucomatous optic neuropathy and visual field loss.
A 59-year-old Asian man with normal tension glaucoma had progressive asymmetric visual field loss OD. Magnetic resonance imaging and angiography of the orbit were performed because of continued progression despite medical and surgical intervention.
Magnetic resonance angiography revealed an anomalous OA, lateral to the carotid artery and emanating from a branch of the middle meningeal artery.
OA anomalies should be added to the differential diagnosis of risk factors for unilateral progressive glaucomatous optic neuropathy, and neuroradiologic imaging should be considered to detect such anatomic variants.
报告一例患有同侧进行性晚期青光眼性视神经病变和视野缺损患者的眼动脉（OA）发育解剖学发现。
一名59岁的亚洲男性患有正常眼压性青光眼，右眼存在进行性不对称视野缺损。尽管进行了药物和手术干预，但由于病情持续进展，遂行眼眶磁共振成像和血管造影。
磁共振血管造影显示眼动脉异常，位于颈动脉外侧，发自脑膜中动脉的一个分支。
眼动脉异常应纳入单侧进行性青光眼性视神经病变危险因素的鉴别诊断中，应考虑进行神经放射学成像以检测此类解剖变异。
