Traumatic chiasm transection is a rare condition characterized by bitemporal hemianopsia following head trauma. In a study of visual complications following head trauma, only 4.4% of patients suffered from chiasmal injuries. Complete transection of the chiasm is even more rare and best visualized using magnetic resonance imaging (MRI). We report the one-year follow-up of clinical, visual field, and MRI findings of a patient with complete transection of the optic chiasm following head trauma.
创伤性视交叉横断是一种罕见病症，其特征为头部外伤后出现双颞侧偏盲。在一项关于头部外伤后视觉并发症的研究中，仅有4.4%的患者患有视交叉损伤。视交叉完全横断更为罕见，采用磁共振成像（MRI）可最佳显示该情况。我们报告了一名头部外伤后视交叉完全横断患者的临床、视野及MRI检查结果的一年随访情况。
