外伤性房角后退的法医学鉴定

Forensic Identification of Traumatic Angle Recession

目的探讨外伤性房角后退的特点及法医学鉴定要点。方法选择2016年1月—2017年6月期间,一所省级眼病专科医院68例(共68只眼睛)有确切眼外伤史的房角后退的案例资料进行回顾性研究,所有案例均行详细的常规裂隙灯、Goldmann氏前房角镜、眼压、眼底、UBM等眼科检查。结果房角后退根据睫状肌撕裂的程度可将其分为三型,范围在0°~360°,前房角镜及UBM可以显现其结构损伤特征,同时可伴有前房出血、眼压升高、视力下降等临床表现。结论房角后退I度、Ⅱ度较为常见,范围多小于180°,与前房出血无必然联系,多数伴有眼压升高、视力下降,前房角镜及UBM是检查的重要手段。

Objective To discuss the characteristics of traumatic angle recession and forensic identification key points.Methods Data of 68 cases(68 eyes)with definite ocular trauma history angle recession from a provincial eye hospital during the period from January 2015 to June 2016 were collected for retrospective study.,All cases were examined by detailed slit lamp,Goldmann's gonioscope,intraocular pressure,ocular fundus and UBM eye examination.Results Angle recession can be divided into three types according to the degree of ciliary muscle tearranged 0~360 DEG.The damage characteristics of the structure can be showed with gonioscope and UBM and may be associated with hyphema,elevated intraocular pressure,decreased visual acuity and clinical manifestations.Conclusion Type I and type II of angle recession is relatively common,with a range of less than 180 degrees and is not necessarily associated with anterior chamber hemorrhage.Most of them were associated with elevated intraocular pressure and decreased visual acuity.Gonioscope and UBM are important means of examination.
