目的 研究使用计算机终端及不同的休息方案对眼表性状的影响.方法 30名受试者均接受5种不同阅读方案:1.连续计算机终端阅读2h后休息10min.(2)连续书本阅读2h后休息10min.(3)连续计算机终端阅读1h后休息10min(休息1方案).(4)计算机终端阅读总时间1h,每30min间隔休息5min(休息2方案).(5)计算机终端阅读总时间1h,每15min间隔休息2min(休息3方案).每次阅读前后分别检查眼部泪膜破裂时间(Brakup Time,BUT)、基础泪液分泌试验(Schirmer I test,Sit)、角膜荧光素染色(Fluorescein Staining,FL)、虎红(Rose Bangle,Rb)染色、结膜印迹细胞(Imprssion Cytology,IC)检查.结果 (1)连续2h计算机终端阅读后较书本阅读更易出现BUT缩短、Sit值减少、FL及Rb染色评分增加(P<0.05).(2)连续计算机终端阅读2h较1h更易出现BUT缩短Sit值减少、FL及Rb染色评分增加(P<0.05).(3)3种休息方案之间的BUT、FL、Rb染色之间的差异具统计学意义(P<0.05),休息3方案优于其它方案.结论 使用计算机终端阅读较书本阅读更易对眼表性状产生影响,并随时间的不同出现差异.三种不同休息方案比较,每使用计算机终端阅读15min间隔休息2min(休息3方案)对眼表性状影响最小.

Objective To evaluate the effects of work-rest schedules on ocular surface for computer terminal readers.Methods Thirty participants underwent 5 reading assignments:(1)2-hourcontinuous com-puter-based reading,followed by 10 minutes rest;(2)2-hour continuous book-based reading,followed by 10minutes rest;(3) 1 hour continuous computer-based reading followed by 10 minutes rest (work-rest schedule 1,WS1);(4) 1-hour computer-based reading with a 5-min breakin every 30 mins (WS2) ;(5)1-hour com-puter-based reading with a 2-min break in every 15 mins (WS3).Before and after reading assignments (afterthe rest),Break-Up time (BUT),Sehirmer I test(SIt),Fluorescent test (FL),rose bangle(Rb),conjuncti-val impression cytology (IC) were measured.Results After reading assignment,people with assignment 1 were more likely to have a shorter BUT,decreased SIt,increased FL and Rb score than in people with assign- ment 2(all with P<0.05).These changes were more profound in people with assignment 1 than in people with assignment 3 (WS1)(all with P<0.05).These changes were more profound in people with WS1/WS2 than inpeople with WS3 (all with P<0.05).Conclusions Computer-based reading is more likely to affect the stabili- ty of ocular Surface than book-based reading.The stability decreases with longer reading time.Compared with WS1 and WS2,WS3 is the optimal reading schedule with least impact on ocular surface.
