To report a case presenting with bitemporal hemianopia due to traumatic chiasmal syndrome after head injury, and to compare the findings with individual case reports published in the literature.
A detailed search was made in PubMed, MedIND, Taylor and Francis online and Wiley online library databases for individual case reports of traumatic chiasmal syndrome. All the case reports were read in full and the findings summarized in a table, which included details of the case who presented with bitemporal hemianopia as an index case.
All published cases of traumatic chiasmal syndrome appear to share some common features, such as injury to the frontal bone and fracture of the anterior skull base. Bitemporal hemianopia and visual acuity have a variable presentation, and do not appear to correlate with severity of injury. Isolated bitemporal hemianopia is rare and clinical improvement may or may not occur.
Traumatic chiasmal syndrome should be considered as a differential diagnosis in patients presenting with bitemporal hemianopia after head injury causing frontal and anterior skull base fracture.
报告一例因头部受伤后创伤性视交叉综合征导致双颞侧偏盲的病例，并将结果与文献中发表的个别病例报告进行比较。
在PubMed、MedIND、泰勒弗朗西斯在线数据库和威利在线图书馆数据库中对创伤性视交叉综合征的个别病例报告进行了详细检索。阅读了所有病例报告全文，并将结果汇总在一张表格中，其中包括以双颞侧偏盲为索引病例的病例详细信息。
所有已发表的创伤性视交叉综合征病例似乎都有一些共同特征，如额骨损伤和前颅底骨折。双颞侧偏盲和视力表现各异，似乎与损伤严重程度无关。孤立性双颞侧偏盲很少见，临床改善可能发生也可能不发生。
对于头部受伤导致额骨和前颅底骨折后出现双颞侧偏盲的患者，应将创伤性视交叉综合征视为鉴别诊断之一。
