摘　　要：[目的]观察计算机视屏显示终端（videodisplayterminal，VDT）作业者视觉异常的临床特点，探讨重度计算机使用者发生青光眼的风险。[方法]以横断面研究，对208例VDT作业者进行问卷调查及常规眼科检查，包括视力、屈光度、裂隙灯显微镜、散瞳前置镜眼底检查、眼压测量、视野检查。根据作业指数，分为低（1～3）、中（4～8）、高（9一16）3组，比较各组视野异常的情况。[结果]在纳入研究的208例中，经全面眼科检查，139例患有不同程度的屈光不正，其中近视125例；视野异常与正常者分别为51例及157例。合并屈光不正的重度VDT作业者有较高的视野异常发生率，组间比较差异具有统计学意义。诊断为开角型青光眼者39例，其中31例（79．5％）合并屈光不正，特别是近视（66．7％，26／39）。[结论]屈光不正者VDT操作时间越长，其视野异常发生率亦随之增高，可能是诱发青光眼的危险因素之一，而近视可能是其视野异常的危险因素。[ Objective ] To investigate the manifestation of visual field abnormalities （VFA） in video display terminal （VDT） users and to assess potential risk of glaucoma in heavy VDT users. [ Methods ] In this cross-sectional study, 208 VDT users were recruited to complete questionnaires and eye examinations, consisting of visual acuity, diopter, fundus, intraocular pressure, and visual field. According to the computer workload index, the participants were classified into three groups： light users （1-3）, moderate users （4-8）, and heavy users （9-16）. The data were analyzed by Z2 test. [ Results ] Among the 208 participants, 139 showed refractive errors, and 125 had myopia; 51 and 157 cases reported positive and negative VFA, respectively. Heavy VDT users with refractive errors showed a significant positive association with VFA. Of the 39 cases diagnosed with open angle glaucoma, 31 had refractive errors and 26 had myopia （66.7%）. [ Conclusion ] Heavy VDT users with refractive errors show an elevated incidence of VFA which could be a risk factor of glaucoma and myopia may contribute to VFA.
