目的:采用病例对照对发生角膜异物的相关危险因素进行分析,并探讨预防的方式。方法:采用病例对照研究,选取我院门、急诊确诊的角膜异物病例123例作为病例组,246例非眼外伤病患,既往无眼外伤史的普通患者对照组,按年龄、性别及类似工作进行1∶2配对,其中年龄差异不超过5岁。调查为问卷调查。结果:外来务工人员比本地工更易发生角膜异物(OR4.73);临时工较固定工人发生角膜异物的几率大(OR9.60);金属加工行业有关的工人较非金属加工行业更易发生角膜异物(OR10.50);高中以下的教育程度在调查中显示较高中以上者易发生角膜异物(OR4.60);工作中不配戴防护镜是发生角膜异物的主要影响因素,调查显示病例组中配戴防护镜的比例明显偏低于对照组(OR7.30)。结论:在多元回归模型中显示临时工、外来务工与金属加工相关工种及不配戴防护镜是发生角膜异物的危险因素。

AIM:To investigate the risk factors of career-related corneal foreign body in Huangpu town of Zhongshan city.METHODS:A total of 123 cases of corneal foreign body were picked out from 446 cases of eye injury during 11 months and 246 subjects of non injury of eye as control were selected from the outpatient,and matched to patients on gender,age and work surrounding with case-control study.Questions were completed face to face by doctors.RESULTS:Temporary employment(OR 9.60,95%CI 5.82-15.90),non-native worker(OR 4.73,95%CI 2.91-7.67),metal-related work(OR 10.50,95%CI 5.79-19.10),below high-school education(OR 4.60,95%CI 2.90-7.29)and not wearing eye protection(OR 7.30,95%CI 4.47-11.90)were risk factors of corneal foreign body.CONCLUSION:In multiple regression model,the risk factors of career-related corneal foreign body include short-term workers,non-native workers,metal-related work and not wearing eye protection.
