方法：将近视患者413例826眼按照等效球镜度数进行分为3组：低度近视(<3.00D，104眼)，中度近视(3.00～6.00D，500眼)，重度近视(>6.00D，222眼)，采用Lenstar 900对所有眼进行检测，得到角膜中央厚度(CCT)、前房深度(AD)、晶状体厚度(LT)、眼轴长度(AL)等参数。各组参数进行方差分析，等效球镜、AL，LT之间相关分析。

结果：不同程度轴性近视患者AL(F=206.16，P<0.01)、AD(F=4.764，P<0.05)存在差异性，而CCT、LT这两项参数无差异性。Person相关分析等效球镜(SE)度数与AL(r=0.662， P<0.01)、AD(r=0.095，P<0.05)呈正相关，与CCT，LT无相关性。AL与AD(r=0.347， P<0.01)、CCT(r=0.126， P<0.01)呈正相关，与LT呈负相关(r=-0.265，P<0.01)。LT与AD呈负相关(r=-0.496，P<0.01)。

结论：近视程度越深，AL和AD越大。等效球镜度数与AD呈正相关。AL与等效球镜度数、AD、CCT正相关，与LT负相关性。LT与AD呈负相关。

METHODS:Totally 413 myopes(826 eyes)were enrolled in this study and were divided into 3 groups: low myopia(myopia <3.00 diopters, 104 eyes), moderate myopia(myopia =3.00-6.00 diopters, 500 eyes)and high myopia(myopia >6.00 diopters, 222 eyes). Central corneal thickness(CCT), aqueous depth(AD), lens thickness(LT), axial length(AL)were measured by Lenstar 900. The parameters were tested using analysis of variance and the relations among SE, AL, LT were analyzed.

RESULTS: There were significant difference both in AL(F=206.16, P<0.01)and AD(F=4.764, P<0.05)and no significant difference both in CCT and LT between these myopia groups. With analysis of Person, the Spherical equivalent(SE)shows a significantly positive correlation with AL(r=0.662, P<0.01)and AD(r=0.095, P<0.05), no correlation with CCT and LT. AL shows a significantly positive correlation with AD(r=0.347, P<0.01)and CCT(r=0.126, P<0.01), negative correlation with LT(r=-0.265, P<0.01). LT shows a significantly negative correlation with AD(r=-0.496, P<0.01).

CONCLUSION: Along with the diopters increasing in myopia, the axial length and aqueous depth continue to increase. Spherical equivalent(SE)shows a significantly positive correlation with AD. AL shows positive correlation with SE, AD and CCT and negative correlation with LT. LT shows a significantly negative correlation with AD.
