We conducted a 19-year review of patients with facial fractures who were treated in the Iranian Maxillofacial Unit at the Mobasher Emergency Hospital, Hamedan Province, Iran, to specifically consider those fractures that resulted in blindness or severe visual impairment.
During the period of February 16, 1984, to March 20, 2003, a total of 2,503 patients with facial fractures were operatively treated. Of these, 550 (22%) patients had orbital region fractures and were specifically studied.
From our facial fractures database, 83 (3.31%) patients were identified as having ocular or extraocular injuries. Of these, 39 patients (1.56%) had severe visual impairment or blindness.
Laterally directed forces are implied as major causative factors in blindness or visual impairment. Males (83.3%), left eye (63.3%), third and fourth age decades (53.3%), and motor vehicle accidents (63.3%) were the most commonly involved gender, site, age, and cause of monocular blindness, respectively.
我们对在伊朗哈马丹省莫巴舍尔急诊医院的伊朗颌面外科接受治疗的面部骨折患者进行了为期19年的回顾性研究，特别关注那些导致失明或严重视力损害的骨折。
在1984年2月16日至2003年3月20日期间，共有2503例面部骨折患者接受了手术治疗。其中，550例（22%）患者有眼眶区域骨折，并进行了专门研究。
从我们的面部骨折数据库中，83例（3.31%）患者被确定有眼内或眼外损伤。其中，39例（1.56%）患者有严重视力损害或失明。
侧向作用力被认为是导致失明或视力损害的主要因素。男性（83.3%）、左眼（63.3%）、第三和第四年龄段（53.3%）以及机动车事故（63.3%）分别是单眼失明最常涉及的性别、部位、年龄和原因。
