摘　　要：对８２例学龄前儿童单纯性屈光参差性弱视眼进行了屈光结构测定和分析。结果表明，正视、近视、远视三种不同屈光状态的角膜曲率半径差异无显著性。两眼轴长度差和晶体厚度差随屈光参差程度而增大（远视：ｒ值分别为０．９３６、０．８９５。近视：ｒ值分别为０．９９３、０．８７２，Ｐ＜０．０１）。提示眼轴长度和晶体厚度共同参与了屈光参差的形成，其中眼轴长度起主导作用，晶体屈光度在匹配和协调中为重要成分。眼轴和晶体的发育不等以及比例失调是形成儿童屈光参差性弱视的解剖基础。Abstract A determination of the refractive structures wasmade for 82 preschool children with simpleanisometropic amblyopia. It was found that therewas no significant difference in radius of corneal cur-vature among the emmetropia, myopia or hyperopia.The differences of bilateral axial lengths and bilaterallens thickness had increased with anisometropic de-gree(hyperopia: r=0.936,0.89 myopia: r=0.993,0.872.P<0.01).The results revealed that theanisometropia was composed of the abnormalities ofthe axial length and the lens thickness,in which thefomer was the dominant factor,the latter was impor-tant component in mating and coordinating. Theimbalances of the growth of the ocular axial and lensas well as their proportion were the anatomical basisof forming children anisometropic amblyopia。
