To assess the time of exposure to the computer and dry eye disease (DED) in subjects with computer vision syndrome (CVS).
A cross-sectional study was conducted in office workers, computer users of both sexes, with an age range of 18-45 years without comorbidities; we included 108 subjects divided into 3 groups according to the time of computer exposure in hours per day (H/D): <4 (n = 23), 4 -7.9 (n = 49), >8 (n = 39). A specific questionnaire was applied to them on the exposure time and the type of visual display terminal (VDT) used, as well as the computer vision symptoms scale (CVSS17). DED was diagnosed with the Ocular Surface Disease Index (OSDI). Ocular surface damage and signs of DED were evaluated with the tear rupture time test (TBUT), the integrity of the ocular surface by ocular surface staining (OSS) and the production of the aqueous basal tear film using the Schirmer test.
Average computer exposure time, measured differently, was positively correlated with DED development. The computer exposure time measured in hours per year and TBUT showed a significant negative correlation (p <0.001) (rho -0.463). Years of computer exposure and staining of the ocular surface showed a significant positive correlation (p <0 0.001; rho 0.404). The accumulated exposure time was negatively correlated with TBUT (p <0.001; rho -0.376) and positively with OSS (p <0.001; rho 0.433). Schirmer test did not correlate with computer exposure time.
The prolonged time of exposure to the computer in subjects with CVS was significantly correlated with the DED tests, in the different ways of measuring it; but not with the Schirmer test.
评估患有计算机视觉综合征（CVS）的受试者接触计算机的时间与干眼病（DED）之间的关系。
对年龄在18 - 45岁、无合并症的办公室工作人员（男女计算机使用者）进行了一项横断面研究；我们纳入了108名受试者，根据每天接触计算机的时间（小时/天，H/D）分为3组：<4小时（n = 23）、4 - 7.9小时（n = 49）、>8小时（n = 39）。对他们应用了一份关于接触时间、所使用的视觉显示终端（VDT）类型以及计算机视觉症状量表（CVSS17）的特定问卷。使用眼表疾病指数（OSDI）诊断DED。通过泪膜破裂时间测试（TBUT）评估眼表损伤和DED体征，通过眼表染色（OSS）评估眼表完整性，并使用泪液分泌试验评估基础泪膜的产生情况。
以不同方式测量的平均计算机接触时间与DED的发生呈正相关。以每年接触计算机的小时数测量的计算机接触时间与TBUT呈显著负相关（p <0.001）（相关系数-0.463）。计算机接触年限与眼表染色呈显著正相关（p <0.001；相关系数0.404）。累积接触时间与TBUT呈负相关（p <0.001；相关系数-0.376），与OSS呈正相关（p <0.001；相关系数0.433）。泪液分泌试验与计算机接触时间无相关性。
CVS受试者长时间接触计算机与DED检测结果在不同测量方式下均显著相关；但与泪液分泌试验无关。
