A 27-year-old woman had a two-year history of proptosis of the right eye associated with recent onset of transient visual loss in that eye on down-gaze only. Ultrasonography and computerized tomography revealed a presumed intraconal cavernous hemangioma of the right orbit. Direct pressure on the optic nerve, with subsequent vascular compromise to the nerve and retina, was felt to be the cause of the transient visual loss. While probably not common as a cause of amaurosis fugax, orbital tumor should be considered in the differential diagnosis of gaze-evoked, transient, monocular visual loss.
一名27岁女性有右眼突出病史两年，近期仅在向下注视时出现该眼短暂视力丧失。超声检查和计算机断层扫描显示右侧眼眶疑似眶内海绵状血管瘤。视神经受到直接压迫，随后神经和视网膜的血管受损，被认为是短暂视力丧失的原因。虽然作为一过性黑矇的病因可能不常见，但在凝视诱发的、短暂的、单眼视力丧失的鉴别诊断中应考虑眼眶肿瘤。
