To describe an unusual case of traumatic globe luxation with optic chiasmal avulsion and review the existing literature on this rare condition for further discussion of mechanisms, diagnosis, and management.
Case report and review of existing case reports and case series identified through literature search.
A 28-year-old woman, with no previous medical history, had left globe luxation and optic chiasm avulsion after being stabbed directly into the left orbit with the use of the stiletto high heel of a shoe. Automated visual field testing detected a temporal hemianopia in the unaffected eye despite normal central visual acuity. Chiasmal avulsion was demonstrated by MRI.
This case suggests that perimetry and MRI should always be considered in traumatic globe luxation to localize the site of injury. Temporal hemianopia in the fellow eye indicates a concomitant chiasmal injury.
描述一例外伤性眼球脱位伴视交叉撕脱的罕见病例，并复习现有文献，进一步探讨该罕见疾病的发病机制、诊断和治疗方法。
通过文献检索，对我们遇到的这例罕见病例进行病例报告，并对现有病例报告和病例系列进行复习。
一位 28 岁女性，既往无任何病史，被鞋的高跟鞋鞋跟直接刺进左眼眶，导致左眼眼球脱位伴视交叉撕脱。尽管中心视力正常，但自动视野检查显示对侧眼出现颞侧偏盲。MRI 显示视交叉撕脱。
该病例提示在外伤性眼球脱位时，应始终考虑使用视野检查和 MRI 来定位损伤部位。对侧眼出现颞侧偏盲提示同时存在视交叉损伤。
