摘　　要：目的:探讨近视眼人群中双眼间近视度数及散光度数大小与主视眼分布特征的相关性。方法:横断面研究。选取2011年12月至2012年12月就诊北京大学人民医院眼科近视眼门诊的1503例双眼近视眼患者。记录患者的主觉验光球镜度数和柱镜度数,使用卡洞法确定主视眼别,比较主视眼和非主视眼的近视屈光度数,分析主视眼分布与双眼间近视度数及散光度数差异的关系。采用配对t检验及χ2检验进行统计学分析。结果:1503例双眼近视眼患者中男性527例,女性976例;年龄17~49岁,中位数为24岁;右眼主视者992例(66.00%),左眼主视者511例(34.00%)。主视眼的球镜、柱镜度数分别为(-5.01±1.91)、(-0.70±0.68)D,非主视眼的球镜、柱镜度数分别为(-5.10±1.99)、(-0.76±0.73)D,主视眼与非主视眼比较差异均有统计学意义(t=2.976,4.319;均P<0.01)。双眼等效球镜度数(SE)差值绝对值(|ΔSE|)≤0.50 D、0.50 D<|ΔSE|≤1.00 D、1.00 D<|ΔSE|≤2.00 D及|ΔSE|>2.00 D患者中,较低近视度数眼为主视眼的比例分别为49.37%(355/719)、51.10%(163/319)、58.48%(100/171)、65.56%(59/90);|ΔSE|越大,较低近视度数眼为主视眼的比例越大,差异有统计学意义(χ2=11.588,P=0.009)。当|ΔSE|≤0.50 D时,双眼柱镜度数差值绝对值(|ΔCyl|)≤0.25 D、0.25 D<|ΔCyl|≤0.50 D及|ΔCyl|>0.50 D患者中,较低柱镜度数眼为主视眼的比例分别为53.94%(89/165)、65.66%(65/99)、69.70%(46/66),|ΔCyl|越大,较低柱镜度数眼为主视眼的比例越大,差异有统计学意义(χ2=6.414,P=0.040)。结论:近视眼人群双眼中较低近视程度眼更多表现为主视眼,这种相关性随着双眼间近视度数(SE)和散光度数差异的加大而增强。(中华眼科杂志,2020,56:693-698)Objective To determine the association between ocular dominance and myopic-astigmatic characteristics in myopic subjects.Methods Cross-sectional study.A total of 1503 myopic subjects visiting from the myopiac clinic from December 2011 to December 2012 were included.The spheres and cylinders were recorded.The ocular dominance was determined by the hole-in-the-card test.The average spherical equivalent(SE)and the cylinder between the dominant eyes and the non-dominant eyes were compared with the paired t test.The associations between ocular dominance laterality and refractive characters were analyzed with the crosstab Chi-square test.Results There were 527 males and 976 females in this study.The median(min,max)of age was 24(17,49)years old.Among the subjects,66.00%(992/1503)of subjects were right-eye dominant,while 34.00%(511/1503)of subjects were left-eye dominant.The dominant eyes had significantly lower average sphere powers[(-5.01±1.91)D vs.(-5.10±1.99)D]and lower average cylinder powers[(-0.70±0.68)D vs.(-0.76±0.73)D]than the non-dominant eyes(t=2.976,4.319;both P<0.01).In the subgroups of|ΔSE|≤0.50 D,0.50 D<|ΔSE|≤1.00 D,1.00 D<|ΔSE|≤2.00 D and|ΔSE|>2.00 D,respectively,the dominant eyes were lower myopic in 49.37%(355/719),51.10%(163/319),58.48%(100/171)and 65.56%(59/90)of the subjects.The inter-group difference was statistically significant(χ²=11.588,P=0.009).In the subgroups of|ΔCyl|≤0.25 D,0.25 D<|ΔCyl|≤0.50 D and|ΔCyl|>0.50 D,the dominant eyes had lower astigmatism in 53.94%(89/165),65.66%(65/99)and 69.70%(46/66)of the subjects,respectively.The inter-group difference was statistically significant(χ²=6.414,P=0.040).Conclusion The ocular dominance laterality is significantly associated with lower myopia and lower astigmatism in the myopic subjects.
