交通伤所致外伤性视神经病变的流行病学特点

Epidemiological study of the case of traumatic optic neuropathy with road traffic trauma

目的探讨道路交通伤致外伤性视神经病变的流行病学特点。方法统计分析1986年11月～2001年10月我院收治的外伤性视神经病变258例的致伤方式、创伤严重程度等特点，对临床反应时间与救治结果进行卡方检验。结果交通伤所致外伤性视神经病变伤员年龄较轻。学生和工人及农民所占比例明显上升；致伤方式多为机动车肇事；摩托车、自行车驾驶者比较常见；致肓原因依致伤后时间不同有所区别，据此可将其分为原发损伤、继发损伤。结论道路交通伤致盲的发生与伤员的年龄、致伤方式、创伤严重程度等因素有关，在伤后不同时间应针对其常见的致盲原因采取相应的防治措施。

Objective To investigate the epidemiologcal characteristics and relative factors of traumatic optic neuropathy case with road traffic trauma. Methods The age, roaduse category, occupation, and injury severity score were observed, and the relation between the injury severity scorc and progress of time was also studied with x^2 statistics. Results The case of traumatic optic neuropathy always happen on the younger patients and worker or peasants with road traffic trauma. Motor vehicle and the bicycle rider were the main woundmaker, The recovery of vision in the case with light perception was significantly better than the recovery in patients receiving no light perception. Significantly difference in improvement was found among patients progress of early time and late time, Conclusions Early dignosis, early treatment. There is significant difference between the features of injury in traffic accidents, and preventive blindness emphasis varies at different phases of clinical course.
