A young woman with only minimal proptosis from a cavernous hemangioma of the left orbit complained of monocular obscurations of vision evoked by right alteral gaze. By analysis of the symptoms, we excluded direct compression of the globe, the optic nerve, and the ophthalmic artery as well as a retinal electrophysiologic phenomenon as a cause of the obscuration. Some vascular phenomenon occurring within the muscle cone appeared to be the most likely explanation. Computer tomography in various positions of gaze revealed the dynamic anatomical relationship between optic nerve and tumor. During adduction, the nerve pressed against and shifted beneath the tumor in the region where the ophthalmic artery crosses over it.
一名患有左侧眼眶海绵状血管瘤且仅有轻微眼球突出的年轻女性，主诉右眼向外侧注视时出现单眼视力模糊。通过对症状的分析，我们排除了眼球、视神经和眼动脉的直接受压以及视网膜电生理现象作为视力模糊的原因。肌锥内发生的一些血管现象似乎是最有可能的解释。在不同注视位置的计算机断层扫描显示了视神经与肿瘤之间的动态解剖关系。在内收时，神经在眼动脉交叉区域被压在肿瘤下方并发生移位。
