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,并分别研究Worth四点法测量优势眼与卡洞法测量优势眼的相关性。方法:选取125例受试者,按照双眼屈光参差的程度分为生理性屈光参差组与病理性屈光参差组。在医学验光基础上分别运用Worth四点法及卡洞法判别双眼中优势眼的眼别。结果:(1)生理性屈光参差组(卡洞法)优势眼眼别与双眼中近视性屈光程度较大眼眼别显著相关(Z=-4.057,P0.05)。(2)Worth四点法和卡洞法测得的优势眼眼别差异无显著性(n=125,P>0.05)。结论:优势眼由基因决定或幼年时期形成并持续维持,而近视性屈光参差可能影响优势眼的选择。优势眼的测量中Worth四点法具有一定的参考意义。
