摘　　要：目的探讨发病早期的儿童和青少年近视的调节功能状态，分析主导眼和非主导眼的调节功能水平。方法应用动态检影法和移近法分别测量50例发病1～2年的学龄期儿童和青少年近视患儿调节滞后和调节幅度；同样方法测量20例正视眼儿童和25例远视屈光不正患儿；检测其主导眼和非主导眼。结果近视患儿的主导眼和非主导眼的调节幅度和调节滞后与正视儿童均差异无统计学意义；而其主导眼和非主导眼的调节幅度比远视患儿明显更大（t=2．21，P=0．03〈0．05；t=2．83，P=0．006〈0．05）；两组的调节滞后差异无统计学意义。50例近视患儿主导眼和非主导眼的调节滞后值分别为（0．73＋031）D和（0．81±0．38）D，主导眼和非主导眼间差异有统计学意义（t=2．14，P=0．038〈0．05）；调节幅度分别为（13．39±3．51）D和（13．26±3．60）D，差异无统计学意义。95例观察对象（近视、正视和远视患儿）的主导眼的调节滞后度为（0．68±0．36）D，非主导眼调节滞后度为（0．75＋0．34）D，主导眼和非主导眼间的差异有统计学意义（t=2．06，19=0．042〈0．05）；主导眼调节幅度（12．9±3．09）D，非主导眼为（12．6±3．09）D，差异无统计学意义（f=1．49，P=0．14）。结论发病早期的儿童和青少年近视的调节滞后值和调节幅度与正视儿童无明显差别；调节幅度比远视儿童的更大。儿童和青少年主导眼的调节滞后比非主导眼的更小，进行调节滞后相关研究时应注意主导眼和非主导眼的区别。Objective To investigate the fimction of accommodation in adolescent myopia and study the differences of accommodation between the dominant and non-dominant eye.Methods Ninety-five subjects （ 50 myopes, 20 emmetropes, 25 hyperopes ）aged 6-15 years, participated.The accommodative lag and ampli- tude of accommodation were assessed with their refi＇active errors corrected.The accommodative lags were as- sessed using MEM dynamic retinoscopy at 40 cm reading distance.Results 1 there were no significant differ- ences of amplitude of accommodation and accommodative lag between the myopia group and emmetropia group.The differences of amplitude of accommodation between the myopia group and hyperopia group were significant （ t =2.21, P =0.03 〈 0.05 ; t =2.83, P =0.006 〈 0.05 ）.2 The difference of accommodative lag between the dominant eye（ 0.73± 0.31 ）D and non-dominant eyes（ 0.81 ± 0.38 ）D in myopia group was significant.3 The accommodative lag of dominant eyes was （0.68 ± 0.36 ）D and it of non-dominant eyes was （ 0.75-± 0.34 ）D, the difference was significant （t =2.06, P =0.042 〈0.05, n =95 ）.There was no significant difference between the amplitude of accommodation of dominant eye（ 12.9± 3.09）D and non-dominant eyes（ 12.6± 3.09）D.Conelu- sion There were no significant differences of accommodative lag and amplitude of accommodation between the adolescent myopes and emmetropes.The accommodative lag of dominant eyes was less than it of the non-dominant eye in adolescent.The differences in accommodative function of dominant and non-dominant eyes should be mentioned.
