外伤性视神经病变的研究进展

Research progress of traumatic optic neuropathy

摘要:

外伤性视神经病变（TON）为头部或颅面部外伤的严重并发症之一，患者多为青壮年，是一种发病率不高但可导致严重视力减退的颅脑外伤并发性疾病，可对患者心理健康及社会适应性产生严重的不良影响。其发病机制尚未明确，临床上易延误确诊，且缺乏统一的治疗指导方案，各治疗手段临床治疗效果各异。本文通过查阅最新相关文献，对TON的病因及发病机制、诊断、治疗等方面的最新研究进展进行综述。

Abstract:

Traumatic optic neuropathy(TON) is one of the serious complications of head or craniofacial trauma. The patients with traumatic optic neuropathy are mostly young adults. It is a complication of craniocerebral injury with low incidence but severe vision loss. It can produce cruel adverse effects on patients' mental health and social adaptation.The pathogenesis of traumatic optic neuropathy has not been clearly defined. It is easy to delay diagnosis clinically. And there is a lack of unified treatment guidelines of TON. Therefore, the clinical benefits of various treatment methods are different. This paper reviewed the progress in etiology, pathogenesis, diagnosis and treatment of traumatic optic neuropathy by referring to the latest relevant literatures.
