摘　　要：目的:探讨近视与双眼视功能状态以及用眼时间的关系。方法:对广州市花都区219名10~12岁的学生进行纵向队列研究,研究对象均于2016年基线检查时进行了眼部生物测定、散瞳下自动验光、主观验光、配镜,并在戴镜2周后测量散瞳验光结果,2017年11月再次重复上述检查。同时做调查问卷收集户外、户内活动时间,进一步比对。结果:219名学生1年后近视度数加深值为-1.05±0.44(P<0.001),眼轴长度1年后增长0.44±0.31,两者呈正相关(P<0.001);近视度数与调节滞后、调节幅度有相关性,同时与周一至周五户外活动时间呈负相关。结论:近视加深速度与调节滞后、调节幅度有关。在用眼时间方面,户外活动时间越短,近视加深越快;户内活动时间越长,近视加深越快。Objective:To evaluate the relationship between myopia progression and binocular vision functions and the relationship between myopia progression and outdoor/indoor activities.Methods:A 1-year longitudinal study was carried out and 219 subjects were included.Subjects lived in Huadu District,Guangzhou,China.Binocular functions measurements,ocular biometry measurements and cycloplegic refraction were done at the first visit in 2016.Cycloplegic refraction were done 2 weeks after dispensing.The measurements were repeated in November 2017 and information about outdoor activities and indoor activities was gathered by questionnaires for comparison.Results:The myopia progression was measured to be-1.05±0.44(P<0.001)in 219 subjects,which was positively correlated with axial length elongation for 0.44±0.31(P<0.001)and correlated with accommodative lag and accommodative amplitude.Myopia progression was observed to be negatively related to outdoor activity time.Conclusion:Myopia progression rate is related to accommodative lag and accommodative amplitude.Outdoor activities could be a protective factor for myopia progression.
