109例视频终端用户视觉障碍的原因对比分析

目的对比调查视频终端用户视疲劳产生原因的特点，探讨如何注意劳动保护。方法收集我院门诊就诊、有眼疲劳主观感受的患者185例，其中视频终端用户109例，其他行业工作者76例，详细询问病史和眼部检查，进行病因分析。定量资料组问比较采用t检验，定性资料组间比较采用检验，等级资料采用秩和检验。结果年龄、性别、主观症状、眼位功能、配镜情况两组差别无统计学意义，日作业时间、屈光检查、泪液分泌功能两组间差别有统计学意义。结论视频终端用户组日视作业时间高于其他行业组；屈光检查结果显示，视频终端用户组屈光不正高于其他行业组；视频终端用户组泪液分泌功能障碍更严重。

Comparative analysis of the muses of 109 cases of visual impairments in video terminal users

Objective To observe and compare the causes of visual fatigue in visual display terminal （ VDT ） user versus other workers, and to discuss how to prevent VDT related visual fatigue. Methods We collected 185 patients presented with subjective feelings of visual fatigue in our hospital. Among them, 109 were VDT users. Comprehensive history and ophthalmic examination were reviewed and the causes of visual fatigue were qualitatively analyzed. Results There was no difference in age, gender, subjective symptoms, eye positions, and prescribed glasses between the two groups of patients. Howevers working time, refractions tear secretion function weresignificantly different between the two groups of patients. Conclusion Working time and refractive error were higher in VDT group. Tear secretion dysfunction was also more severe in VDT group.
