视屏显示终端作业人员干眼及眼表损害情况调查

Investigation of dry eye and ocular surface damage of terminal operator in video display

目的调查视屏显示终端(VDT)作业人员干眼症患病现状及其眼表损害情况,分析VDT作业人员干眼症的影响因素。方法采用整群抽样法抽取某单位VDT作业人员260人为研究对象,统一接受常规眼科检查,测定泪膜破裂时间(BUT)、泪腺分泌试验(SIt)、角膜荧光染色评分、瞬目次数等,采用眼表疾病指数(OSDI)评价其生活质量,采用问卷调查表调查干眼症的影响因素。结果共发放问卷260份,有效回收258份,有效回收率为99.23%。258例研究对象中,确诊干眼患者123例,检出率为47.67%。单因素及logistic回归分析显示,年龄、工龄、佩戴眼镜、屏幕放置位置及距离、使用VDT时间、工间休息时间及视觉环境均是VDT作业者干眼的影响因素(P<0.05)。结论VDT作业人员具有较高的干眼症患病风险且伴有潜在性眼表损害,与VDT职业暴露因素有关。

Objective To investigate the current situation of dry eye disease and its damage to the eye surface in workers at video display terminal(VDT),and analyze the influencing factors of dry eye disease in VDT workers.Methods 260VDT operation workers from a company were selected through cluster sampling method,and were tested for routine ophthalmologic examination,determination of time(BUT),lacrimal gland secretion appears burst test(SIt)and corneal fluorescence staining scores and the number of instantaneous to discuss.The ocular surface disease index(OSDI)was used for evaluation of the quality of life,through questionnaire to investigate the influence factors of dry eyes.Results A total of 260questionnaires were issued,and 258were effectively recovered,with an effective recovery rate of 99.23%.Among the 258cases,123were diagnosed with dry eye,with a detection rate of 47.67%.Univariate logistic regression analysis showed that age,length of service,glasses wearing,screen position and distance,VDT time,rest time and visual environment were all influential factors for dry eyes of VDT workers(P<0.05).Conclusions VDT workers have a higher risk of xerophthalmia with potential ocular surface damage,which is related to VDT occupational exposure factors.
