To highlight the various causes of gaze-evoked amaurosis.
Retrospective noncomparative interventional case series.
Five patients treated at our facility over the past 6 years.
Clinical presentation, radiologic studies, surgical management, and postsurgical results are presented.
Visual acuity, clinical findings of gaze-evoked amaurosis.
Only two patients had classic intraorbital etiologies, one with an intraconal cavernous hemangioma and one with an intraconal foreign body. Three patients had extraorbital processes, two with orbital fractures and one with a sinus tumor. Only two of our patients initially were aware of the gaze-evoked amaurosis at presentation. Appropriate surgery was curative in all cases.
Gaze-evoked amaurosis is a rare condition, classically implicating intraconal orbital pathology. In one of the largest case series published to date, we found extraorbital etiologies are also capable of producing gaze-evoked vision loss. Gaze-evoked amaurosis should be suspected and tested for in any orbital condition.
强调注视诱发黑矇的各种病因。
回顾性非对照性干预病例系列。
过去6年在我们机构接受治疗的5名患者。
介绍临床表现、影像学检查、手术治疗及术后结果。
视力、注视诱发黑矇的临床发现。
仅2例患者有典型的眶内病因，1例为眶内海绵状血管瘤，1例为眶内异物。3例患者有眶外病变，2例为眼眶骨折，1例为鼻窦肿瘤。我们的患者中只有2例在就诊时最初意识到有注视诱发黑矇。所有病例经适当手术均治愈。
注视诱发黑矇是一种罕见疾病，经典地提示眶内病变。在迄今为止发表的最大病例系列之一中，我们发现眶外病因也可导致注视诱发的视力丧失。在任何眼眶疾病中均应怀疑并检测注视诱发黑矇。
