| ［摘要］ 目的 探讨屈光参差性近视患者屈光度与高阶像差的相关性。方法 选择2009-08～2010-02在广西视光中心就诊的屈光参差性近视患者60例（120眼），其中男22例，女38例，年龄8～40(21.2±7.4)岁。使用美国AMO公司的WaveScan波前像差仪采集每位患者双眼的波前像差数据，将屈光参差患者双眼数据分别列入高屈光度数眼组［等效球镜为（-4.81±1.79） DS］和低屈光度数眼组［等效球镜为(-2.44±1.78）DS］。运用SPSS13.0统计软件采用Pearson相关检验分别对高屈光度数眼组和低屈光度数眼组的屈光度和其总高阶像差（High order aberrations,HOA）、彗差（Coma）、三叶草像差（Trefoil）、球差（Spherical aberration,SA）等指标进行相关分析。结果 高屈光度数组与低屈光度数组的总高阶像差分别为(0.37±0.15)μm、(0.37±0.14)μm；彗差分别为(0.21±0.14)μm、(0.19±0.11)μm；三叶草像差分别为(0.16±0.10)μm、(0.17±0.12)μm；球差分别为(0.11±0.14)μm、(0.12±0.17)μm。Pearson相关检验结果提示：仅高度数眼组的屈光度与其总高阶像差存在相关性（r=-0.275,P<0.033），其余均无相关性（P>0.05）。结论 屈光参差性近视患者的高度数眼与其总高阶像差之间存在低度相关性。 |

| ［Abstract］ Objective To analyze the correlations of refractive power and wavefront aberrations in anisomyopes by WaveScan WaveFrontTM System.Methods Sixty anisomyopic patients(male 22, female 38), aged 8 to 40 years old(mean 21.2±7.4), in vision science and optometry center of Guangxi from August 2009 to February 2010, were enrolled in this study and wavefront aberrations in each eyes were captured for analyzation. And more myopic eyes with spherical equivalent (-4.81±1.79) DS, less myopic eyes with spherical equivalent (-2.44±1.78) DS. The outcomes included high order aberrations, coma, trefoil and spherical aberration. Pearson correlations between spherical equivalent and high order aberrations, coma, trefoil and spherical aberration were analyzed by SPSS13.0, respectively.Results High order aberrations in more myopic eyes and less myopic eyes were (0.37±0.15)μm and (0.37±0.14)μm, respectively. Coma were (0.21±0.14)μm and (0.19±0.11)μm, respectively. Trefoil were (0.16±0.10)μm and (0.17±0.12)μm, respectively. Spherical aberration were (0.11±0.14)μm and (0.12±0.17)μm, respectively. Pearson correlations showed that there were low correlations between spherical equivalent and high order aberrations in more myopic eyes(r=-0.275, P<0.033), but there were no correlation among other indexes(P>0.05).Conclusion Low correlations existed between spherical equivalent and high order aberraions in more myopic eyes of anisomyopia. |
