Ten patients with orbital fractures and optic nerve trauma are reported. Fractures of the optic canal could be demonstrated by computed tomography in six cases and fractures of the orbital apex in another three cases. Surgical decompression of the optic canal was performed in seven cases. Computed tomography enhanced decision for surgery in cases of intraorbital haematoma with exophthalmus and narrowing of the canal by bony fragments, especially in those patients presenting with incomplete or progressive visual disturbance.
报告了10例眼眶骨折合并视神经损伤的患者。6例患者经计算机断层扫描显示视神经管骨折，另外3例显示眶尖骨折。7例患者接受了视神经管减压手术。计算机断层扫描有助于决定对伴有眼球突出和骨碎片致神经管狭窄的眶内血肿患者进行手术，尤其是那些出现不完全或进行性视力障碍的患者。
