摘要
目的 分析52例57眼外伤性视神经病变（traumatic optic neuropathy，TON）的流行病学情况。方法 对2002年2月～2005年5月间，作者诊治的确诊为TON者52例情况分析。结果 52例中，19．45岁青壮年占75．00％，8～18岁儿童和青少年占19．23％。男性占94．23％。致伤原因：摩托车摔伤50％，其他机动车肇事13．46％，高空坠落17．31％，其他19．23％。单纯眉弓外侧受伤40．38％，颌面和眶周损伤46．16％，头部受伤13．46％。伤后视力无光感者占68．42％。治疗总有效率为35．09％，而24h内就诊者有效率为75．00％，就诊时间与治疗效果显著相关（P=0．012）。结论 TON视力损伤严重，预后差。未戴头盔骑摩托车摔伤是首要致伤因素。加强交通安全法规教育和高空作业防护有重要意义。普及TON诊断和治疗知识，第一时间有效救治可改善预后。
Objective To overview and analysis the epidemiological features of traumatic optic neuropathy（TON）. Methods 52 cases （57 eyes） with TON were analyzed from Feb,2002 to May,2005. Results Of 52 cases,39 cases （75%） were in 19-45 years old group; 10 cases （19.23 % ） in 8- 18 years old children and juvenile group. And 49 cases （94.23%） were male. Vulnerating causes：50.00% of injuries were caused by motorcycle accidents ,and 13.46% by other traffic accident; 17.31% by falling; 19.23% by other causes. Injured positions：21 cases （40.38%） were only at lateral superciliary arch, 24 cases （46.16%） at the maxillofacial and periorbital region,7 cases （13.46%） at the skull, respectively. 39 eyes （68.42 % ） was found no light perception after trauma. The total effective rate of treatment was 35.09 %. There was a significant relevance between the starting treatment time after trauma and therapeutic effects （ P = 0.012）. Conclusion Visual impairment of TON was severe, its prognosis was very poor. The main cause were traffic accident and falling down. The suitable preventive measures should be carried out according to its epidemiological features. The prompt diagnosis and treatment may improve the visual outcome.
