优势眼与近视的关系研究

The dominant eye in myopes

目的 :研究优势眼眼别与其两眼中近视性屈光程度较大眼的眼别关系。方法 :16 5个受试者 ,按照双眼屈光参差的程度分双眼屈光无显著差异组、生理性屈光参差组与病理性屈光参差组三组。在医学验光基础上 ,结合简化的卡洞法与拇指法判别双眼中的优势眼眼别。结果 :①对于所有个体 ,优势眼眼别与双眼中近视性屈光程度稍大眼眼别显著相关 (Z =- 3.6 2 1,P <0 .0 0 0 1)。②双眼屈光无差异组优势眼眼别与其两眼中近视性屈光程度较大眼眼别显著相关 (P <0 .0 0 0 1) ,但在生理性屈光参差组与病理性屈光参差组 ,两者均无显著相关 (P >0 .0 5 )。③各组均以右优势眼居多 ,右眼屈光不正较大者居多。结论 :优势眼的选择可能早于双眼近视性屈光参差的发生 。

Objective:To study the relationship between the dominant eye and the eye with higher myopia among myopes.Methods:165 volunteers were enrolled and tested by using the simplified hole in the hand method. They were divided into three groups according to degree of anisometropia:non anisometropia,physiological anisometropia,and pathological anisometropia. The relationship between the dominant eye and the eye with higher myopia for the two eyes of each subject was analyzed with the non parametric Wilcoxon Signed Ranks Test of SPSS 11.0 software. The chi square test was also used to analyze the distribution of sight dominance and the eye with higher myopia among the three groups.Results:Eye dominance was significantly associated with the higher mypoic eye in the non anisometropia group(P<0.0001). However,this did not differ significantly from the physiological anisometropia group nor the pathological anisometropia group(P>0.05). Dominant eyes and eyes with higher myopia were significantly related to the right eye in each group.Conclusion:A dominant eye may develop before anisometropia,and anisometropia may affect the choice of a dominant eye.
