PURPOSE
To report a clinical case of optic nerve compression by supraclinoidal internal carotid artery associated with optociliary shunt vessels.
METHODS
A 78-year-old woman with the clinical triad of left visual loss, ipsilateral optic disc pallor, and retinochoroidal (optociliary) shunt vessels is reported. She complained of loss of vision in the left eye of 2 years'' duration.
RESULTS
A diffuse depression of the visual field was found in the affected eye. Magnetic resonance imaging revealed left optic nerve compression by the supraclinoidal internal carotid artery.
CONCLUSIONS
The occurrence of optociliary shunt vessels, visual loss, and optic atrophy is a nonspecific sign of chronic optic nerve compression and in some instances may be falsely localized.
目的
报告1例伴有视睫状分流血管的鞍上颈内动脉压迫视神经的临床病例。
方法
报告1例78岁女性，有左眼视力丧失、同侧视盘苍白和视网膜脉络膜（视睫状）分流血管的三联征。她主诉左眼视力丧失2年。
结果
患眼发现视野弥漫性缺损。磁共振成像显示鞍上颈内动脉压迫左侧视神经。
结论
视睫状分流血管、视力丧失和视神经萎缩的出现是慢性视神经压迫的非特异性征象，在某些情况下可能会出现定位错误。
