摘要
目的 探讨学龄儿童眼屈光发育与眼生物参数、身体发育参数的相关性,通过佩戴眼镜夹扣Clouclip M2采集儿童用眼行为及用眼环境数据。方法 受检学生佩戴可穿戴设备眼镜夹扣Clouclip M2进行7 d的用眼行为及环境监测(包含5个工作日和2个休息日)。第8天时,学生由家长陪同到院获取Clouclip M2监测数据报告,并接受眼屈光度、眼生物参数、身体发育参数等检查。评估儿童眼屈光发育与身体发育参数、眼生物参数、用眼行为及用眼环境的关系。结果 不同年级学生的身体发育参数[身高、体质量、体质量指数(BMI)]差异均有统计学意义(P<0.01),不同年级学生眼生物参数[等效球镜(SE)、眼轴长度(AL)、角膜曲率半径(CR)、晶体厚度(LT)、中央角膜厚度(CCT)、前房深度(ACD)]差异均无统计学意义(P>0.05)。SE与AL、ACD、LT、CR存在相关性(P<0.05),与CCT、身高、体质量、BMI无相关性(P>0.05)。平均每日视近时间≥300 min、单次视近最长时间≥80 min、平均视近距离<33 cm、平均每日暴露次数<8次、白天光照强度<200 lux、夜晚光照强度<125 lux者近视概率较高。结论 身体发育并不是影响学龄儿童眼屈光发育的敏感指标,用眼行为及用眼环境对儿童近视形成起重要作用。平均每日视近时间≥300 min、单次视近时间≥80 min、视近距离<33 cm、每日有效户外暴露次数<8次、白天光照强度<200 lux等因素是近视发生的危险因素。眼镜夹扣Clouclip M2可连续监测儿童用眼行为,为指导临床儿童科学用眼提供依据。
Objective To explore the correlations of eye refractive development with ocular biological parameters and physical development parameters in school-age children,and to collect data on children′s eye-using behavior and environment by using eyeglass clip Clouclip M2.Methods The tested students wore wearable device eyeglass clip Clouclip M2 for 7 days of eye-using behavior and environmental monitoring(including 5 working days and 2 rest days).On the eighth day,students were accompanied by their parents to the hospital for obtaining Clouclip M2 monitoring data reports,and they were also conducted with examinations such as eye diopter,eye biological parameters,and physical development parameters.Relationships of children′s eye refractive development with physical development parameters,eye biological parameters,eye-using behavior and eye environment were evaluated.Results There were significant differences in physical development parameters[height,body mass and body mass index(BMI)]among students in different grades(P<0.01),but there were no significant differences in eye biological parameters[spherical equivalent(SE),axial length(AL),corneal curvature radius(CR),lens thickness(LT),central corneal thickness(CCT)and anterior chamber depth(ACD)]among students in different grades(P>0.05).SE was correlated with AL,ACD,LT and CR(P<0.05),but had no correlations with CCT,height,body mass and BMI(P>0.05).The probability of myopia was higher in individuals with an average time of watching at a close distance≥300 minutes per day,the longest time of watching at a close distance≥80 minutes for one time,an average distance of watching at a close range<33 cm,an average exposure<8 times per day,light intensity at daytime<200 lux and light intensity at nighttime<125 lux.Conclusion Physical development is not a sensitive indicator affecting the refractive development of eyes in school-age children,and eye-using behavior and environment play important roles in the formation of myopia in children.An average time of watching at a
