摘　　要：目的比较近视屈光参差患者主导眼与非主导眼的等效球镜度，散光度及眼轴长度，研究主导眼与屈光不正度的关系。方法临床病例回顾性研究。对2009年7月至2014年6月在天津职业大学眼视光工程学院近视屈光参差的学生，经眼部检查排除各种眼病，进行主客观验光、主导眼（卡洞法）及眼轴长度的测定。统计处理采用χ2检验，Wilcoxon符号秩检验及配对t检验。结果主导眼的等效球镜度（-3．65±2．24）D比非主导眼（-2．64±2．20）D高（t=-3．05，P=0．003〈0．005），散光度低（Wilcoxon符号秩检验z=-1．26，P=0．21〉0．05），眼轴更长，分别是（24．63±0．90）mm，（24．22±1．03）mm（t=3．49，P=0．001〈0．005）。尤其是当近视屈光参差介于1．00-2．49D之间时，主导眼散光度数低于非主导眼（Wilcoxon符号秩检验，Z=2．84，P=0．005）。在69例近视屈光参差学生中，右眼为主导眼的占73．9％，左眼为主导眼占26．1％；近视屈光参差在1．00-2．49D和2．50D以上时高度眼与主导眼一致率的分别为76．5％和62．9％。结论近视屈光参差患者主导眼比非主导眼的近视程度深，眼轴长，主导眼倾向于右眼并倾向于与高度眼一致。Objective To investigate the refractive error and axial length between dominant eye and nondominant eye in patients with myopic anisometropia, explore the association between domi- nant eye and refractive error. Methods A total of 69 myopic anisometropia subjects with corrected distance vision acuity ≥0.8 were enrolled, all kinds of eye diseases were excluded. Refractive error, axial length and ocular dominance were measured in all patients. Statistic analysis used χ2 test, Wil- coxon test and Paired t test. Results Dominant eye （-3.65±2.24D） were more myopic than nondomi- nant eye （2.64±2.20D, paired t test, P 〈0.005）; less astigmatism （Wilcoxon test, P 〉0.05）; dominant eye had a longer axial length than nondominant eye （24.63±0.90mm vs 24.22±1.03mm, respectively, Paired t test, P 〈0.005, Especially when the degree of myopic anisometropia was between 1.00D and 2.49D, dominant eye had lower astigmatism than nondominant eye （Wilcoxon test, P 〈0.05）. Right and left ocular dominance was noted in 73.9% and 26.1% of the individuals; dominant eyes were more myopic in 76.5% and 62.9% when the myopic anisometropia was 1.00-2.49D and over 2.50D. Conclusions The present study shows the dominant eye has a greater degree of myopia, ax- ial length than the nondominant eye in myopic anisometropia. The dominant eye tends to be the more myopic eye.
