| 中文摘要: |
| 目的 评价CT对间接视神经损伤的诊断价值。方法 对临床诊断为间接视神经损伤的106例112只眼CT检查结果进行研究。结果 112只眼中发生眶壁骨折84只眼,占75%,其中以内壁骨折最为常见。49只眼有明确视神经管骨折,占43.8%,24只眼既无明显视神经管骨折,又无眶壁骨折及窦腔积液,占21.4%。视神经增粗者16只眼,占14.3%。结论 CT可较好地显示眶壁骨及眶内视神经形态,对间接视神经损伤的诊断及选择治疗方案具有重要的价值。 |

| Objective To evaluate the differential diagnostic value of CT in patients with indirect optic nerve trauma. Methods CT findings of 112 eyes in 106 patients, who were clinically confirmed with indirect optic nerve trauma were analyzed. Results Orbital fractures of 84 eyes were observed in the 112 eyes,accounting for 75%.Of that,medial orbital walls were most common. Canal fratures were involved demonstrably in 49 eyes (43.8%).There were 24 eyes without any fracture and paranasal sinus dropsy (21.4%),16 eyes with swelling of optic nerve (14.3%). Conclusion CT could well show orbital bone walls and optic nerve in the orbit, and play an important role in the diagnosis of optic nerve injury and selecting the remedy. |
