To report the computed tomography features of a case with complete luxation of the globe after a road traffic accident.
A 35-year-old male presented with pain, loss of vision, and bleeding from the left eye 48 hr after a road traffic accident. The ophthalmic examination of the left upper and lower eyelids showed edema with subcutaneous hematoma, crepitus, and complete blepharoptosis. On retracting the eyelids, the left eyeball was not visible and the patient was not able to perceive light. The left temporal region appeared filled with a soft, palpable globular structure situated beneath the temporalis muscle. A non-contrast computed tomography (NCCT) of the head and orbits showed a comminuted and displaced fracture of the floor, medial, and lateral orbital walls in addition to a displaced tripod fracture of the left zygomatic bone. The intact left eyeball was seen below the temporalis muscle without any optic nerve or extraocular muscle attachment. The virtual reality reconstruction highlighted a contributory supero-temporal defect in the bony orbit, which appeared large enough to accommodate the intact eyeball.
The computed tomography of the orbits provided a detailed location of the luxated eyeball and provided guidance in further management of the case.
报告1例道路交通事故后眼球完全脱位病例的计算机断层扫描特征。
一名35岁男性在道路交通事故后48小时出现疼痛、视力丧失和左眼出血。左上睑和下睑的眼科检查显示水肿伴皮下血肿、捻发音和完全性上睑下垂。翻开眼睑后，左眼眼球不可见，患者无法感知光线。左颞区似乎充满了位于颞肌下方的柔软、可触及的球状结构。头部和眼眶的非增强计算机断层扫描（NCCT）显示眶底、内侧和外侧眶壁粉碎性移位骨折，以及左侧颧骨移位的三脚架骨折。完整的左眼眼球可见于颞肌下方，无任何视神经或眼外肌附着。虚拟现实重建突出显示眼眶骨的颞上侧有一个导致眼球脱位的缺损，该缺损似乎大到足以容纳完整的眼球。
眼眶计算机断层扫描提供了脱位眼球的详细位置，并为该病例的进一步处理提供了指导。
