目的探讨外伤性视神经病变的磁共振成像(MRI)影像学特征与诊断价值.方法回顾性分析我院2007年9月至2010年12月间收治的52例(56眼)外伤性视神经病变的临床和MRI影像学资料.结果发现阳性体征的49眼,占87.50％,其中眼眶侧壁骨折15眼(占全组56眼的26.79％),眶内软组织水肿32眼(57.14％),眶内出血39眼(69.64％),视神经水肿25眼(44.64％),视神经鞘膜下出血8眼(14.29％),视神经移位2眼(3.57％),视神经萎缩24眼(42.86％).结论 MRI具有较为明显的软组织分辨率的特点,对外伤性视神经病变的早期诊断具有重要价值,为损伤后及时治疗提供良好的依据.

Objective To find out the characteristics and diagnostic value of MRI of traumatic optic neuropathy.Methods We retrospectively analyzed 52 cases (56 eyes) of traumatic optic neuropathy with MRI and clinical data during Sep,2007 to Dec,2010.Results There were positive MRI results in 49 eyes ( 87.50％ ),including 15 eyes (26.79％) of orbital fracture,32 eyes (57.14％) of soft tissue edema,39 eyes (69.64％) of hemorrhage,25 eyes (44.64％) of optic edema,8 eyes ( 14.29％ ) of subdural hematoma,2 eyes(3.57％ ) of optic nerve transposition and optic atrophy in 24 eyes (42.86％).Conclusion MRI scanning has the characteristic of obviously soft tissue distinguishability,which has great value in the diagnosis of traumatic optic neuropathy and treatment.
