OBJECTIVES
To clarify the relation between the prevalence of dry eye syndrome and subjective symptoms of asthenopia in visual display terminal (VDT) operators.
METHOD
722 VDT workers (242 subject workers with symptoms of asthenopia and 480 controls without such symptoms) without obvious organic ocular diseases received an ophthalmological examination consisting of refractometry and a tear function (phenol red thread) test.
RESULTS
More than 30% of symptomatic workers were found to meet the criteria of dry eye, and the odds ratio compared with the controls was 4.61 (p < 0.001). This odds ratio was significantly greater than that obtained for refractive errors (2.31).
CONCLUSIONS
Although this cross sectional study could not prove that dry eyes are the cause of asthenopia, the profound association of dry eyes with symptoms of asthenopia could be verified. It would be useful to carry out tear function tests in workers with symptoms of asthenopia.
目的
阐明视屏终端（VDT）作业人员干眼综合征患病率与视疲劳主观症状之间的关系。
方法
722名无明显器质性眼病的VDT作业人员（242名有视疲劳症状的受试人员和480名无此类症状的对照人员）接受了包括验光和泪液功能（酚红棉线）测试在内的眼科检查。
结果
发现超过30%有症状的受试人员符合干眼标准，与对照组相比的优势比为4.61（p<0.001）。该优势比显著高于屈光不正的优势比（2.31）。
结论
虽然这项横断面研究不能证明干眼是视疲劳的病因，但干眼与视疲劳症状之间的密切关联可以得到证实。对有视疲劳症状的作业人员进行泪液功能测试将是有益的。
