目的：观察调节滞后与青少年近视的相关性。方法随机抽取临床工作中10～12周岁青少年近视患者121例，依据调节功能正常、超前、滞后分组，其中调节正常组23例（46只眼）、超前组36例（72只眼）、滞后组62例（124只眼），通过1年的追踪观察，对比分析每1组青少年近视屈光度变化数据。结果调节滞后与调节正常组比较， P ＜0．05，具有统计学意义，调节滞后组更容易导致近视加深；调节滞后与调节超前组比较， P ＜0．05，具有统计学意义，调节滞后更容易导致近视加深；调节超前与调节正常组比较， P ＞0．05，两组有差别，未达到统计学差异。结论调节滞后与青少年近视进展具有相关性，调节滞后更容易导致近视加深。%Objective To investigate the relationship between accommodation lag and juvenile myopia.Methods Author recruited 121 myopic adolescents of 10-12 years old.Based on accommodation response time, subjects were di-vided into three groups:normal (46 eyes, 23 subjects), advancing (72 eyes, 36 subjects) and lag (124 eyes, 62 sub-jects) .Diopter changes during the following year were collected and correlated with original grouping results.Results The diopter in subjects with accommodation lag was significantly more myopic than those in subjects with normal accommo-dation or advance accommodation ( both P <0.05) .There was no difference between the latter two groups.Conclusion A significant correlation existed between lag accommodation and the progression of myopia in adolescents of 10-12 years of age.
