视频显示终端使用时间及睡眠时间与儿童干眼的关系

摘要

目的 探讨儿童干眼的临床特点及其与不同视频显示终端(VDT) 使用时间、睡眠时间之间的关系.方法 收集符合成人干眼诊断标准的儿童89例(178眼) 作为观察组,无眼部不适症状的儿童38例(76眼) 作为对照组,进行双眼泪膜破裂时间(BUT) 、角膜荧光素染色(CFS) 、泪液分泌试验(SIT) 检查,比较两组间不同VDT(分别为手机、电脑、电视) 使用时间及睡眠时间的差异.结果 89例干眼儿童中频繁眨眼51例(57. 3％) ,眼痒29例(32. 6％) ,异物感15例(16. 9％) ,眼红15例(16. 9％) .观察组BUT 值明显低于对照组(P ＜ 0. 05);观察组CFS 阳性率明显高于对照组(P ＜ 0. 05);两组间SIT 结果 差异无统计学意义(P ＞ 0. 05);观察组平均每天睡眠时间低于对照组,平均每天使用电脑时间高于对照组,差异有统计学意义(P ＜ 0. 05);二元logistic回归模型结果: 平均每天使用电脑时间较长的儿童更容易患干眼(OR = 1. 851,P ＜ 0. 05) ,而平均每天睡眠时间较长的儿童更不容易患干眼(OR = 0. 621,P ＜ 0. 05) .结论 使用电脑可能是儿童干眼的危险因素,睡眠可能是儿童干眼的保护因素.%Objective To investigate the clinical characteristics of dry eye in children and its correlation with the time of use of different video display terminals (VDT) and sleeping time. Methods Eighty-nine children (178 eyes) accordant to the adult dry eye diagnostic criteria were enrolled as the observation group. Thirty-eight children (76 eyes) with no eye symptoms were treated as control group. The tear film break-up time (BUT), corneal fluorescing staining (CFS), and Schirmer test I (SIT) were compared between the 2 groups. The times of using different VDTs (mobile phones, computers, televisions) and the sleep time were also compared. Results Among the 89 cases of dry eye, frequent blinking, itchy eyes, foreign body sensation and red eyes were presented in 51 cases (57. 3％), 29 cases (32. 6％), 15 cases (16. 9％) and 15 cases (16. 9％), respectively. The BUT value of the observation group was significantly lower than that of the control group (P ＜ 0. 05). The positive rate of CFS in the observation group was significantly higher than that in the control group (P ＜ 0. 05). There was no significant difference in SIT between the two groups (P ＞ 0. 05). The average daily sleep time of the observation group was significantly lower than that of the control group; and the average daily use of computer time was significantly higher than that of the control group (P ＜ 0. 05). The longer daily use of computer was a risk factor of dry eye (OR = 1. 851, P ＜ 0. 05); and longer daily sleep duration was a protective factor from dry eye (OR = 0. 621, P ＜ 0. 05). Conclusion The use of computers may be a risk factor for dry eye in children, and sleep may be a protective factor.
