头部外伤合并视神经损伤的临床分析

目的探讨头部外伤与视神经损伤的相关因素。方法回顾性分析88例外伤性视神经病变患者的临床资料。以致伤原因、伤后视力为最终结果,通过临床相关检查分析头部外伤与视神经损伤预后的关系。结果伤后视力无光感比有光感以上视力(P=0.0069)、伤后有昏迷比伤后无昏迷(P=0.0030)、伤后视神经管骨折比无骨折、视觉诱发电位(VEP)检查熄灭型比非熄灭型最终视力的恢复危险度增加。结论伤后视力无光感、昏迷、视神经管骨折是影响视神经损害预后的危险因素。视神经管断层摄影及视觉诱发电位检查是评价预后的有效指标。

Clinical analysis of head injury accompanied with optic nerve injury

Objective To study the factors of head injury accompanied with optic nerve injury. Methods The 88 head injury patients accompanied with optic nerve injury were retrospectively analyzed. Multiple variable analysis was done to find the risk factors associated with prognosis in traumatic optic neuropathy. Results The outcome of visual acuity was poorer in patients with the following conditions: no light perception after trauma(P=0.0069),loss of consciousness(P=0.003),fracture of the optic canal and absence of visual evoked potential(VEP). Conclusion Traumatic optic neuropathy includes direct and undirect injury type. The intial visual acuity of no light perception,loss of consciousness,and fracture of the optic canal are the risk factors associated with prognosis in traumatic optic neuropathy. Optic canal CT and VEP were effective indicators of prognosis in traumatic optic neuropathy.
