目的 探讨近视青少年中央角膜厚度(CCT)的变异程度及CCT与年龄、屈光度、眼轴长度、性别及眼别的关系.方法 横断面研究.应用Stratus光学相干断层扫描(OCT)仪测量143例(143眼)7～18岁近视青少年的中央角膜厚度,并用A超测定眼轴长度,散瞳行屈光检查.在进行影响因素分析时行双变量直线回归分析.结果 143眼的CCT为(549.3±35.7)μm.双变量简单直线回归分析显示CCT与年龄(r=0.065,P＞0.05)、性别(r=0.059,P＞0.05)、眼别(r=0.125,P＞0.05)、眼轴长度(r=0.146,P＞0.05)均不相关,但与等效球镜度呈正相关(r=0.250,P＜0.01),回归方程为(Y)=561.458+4.514X(F=9.417,P＜0.01).多元逐步回归分析显示CCT仍仅与等效球镜度呈正相关(r=0.247,P＜0.01),回归方程为(Y)=561.096+4.465X(F=8.813,P＜0.01),而与其他几个因素不相关.结论 Stratus OCT可以很好地测量青少年的CCT.青少年的CCT随着近视度的增加而变薄,但不随眼轴长度的增加而变薄.

Objective To investigate the relationship between central corneal thickness (CCT) measured by optical coherence tomography (OCT) and age,spherical equivalent(SE),axial length,gender,and right vs.left eye in myopic juveniles.Methods This was a cross-sectional study.One hundred and forty-three juveniles (age range,7～18 years) underwent ophthalmic examination.CCT was measured by a Stratus OCT on one randomly selected eye of each subject.Axial length was measured by A-scan ultrasound.SE was measured after cycloplegia.The effects of several factors (age,SE,axial length,gender,and right vs.left eye) on CCT were investigated in univariate regression analyses and multivariate stepwise regression analyses.Results The mean CCT was 549.3±35.7 μm.In univariate regression analysis,no correlation was found between CCT and age (r=0.065,P＞0.05),gender (r=0.059,P＞0.05),refractive status (r=0.125,P＞0.05),or axial length (r=0.146,P＞0.05).There was a significant positive correlation between CCT and SE (r=0.250,P＜0.01).The regression equation was (Y)=561.458+4.514X (F=9.417,P＜0.01).In multivariate stepwise regression analysis,there was also a significant positive correlation between CCT and SE (r=0.247,P＜0.01).The regression equation was (Y)=561.096+4.465X (F=8.813,P＜0.01).And the following parameters were not significantly associated with CCT:age,gender,right vs.left eye,or axial length.Conclusion The Stratus OCT is a good instrument to measure children's CCT.Among Chinese myopic juveniles,CCT did not correlate with axial length,age,gender or right vs.left eye,but showed a direct correlation with SE.
