  目的:观察正常人与高度近视患者在角膜厚度、上皮厚度及眼轴长度方面的差异.方法:97例正常眼和48例高度近视眼纳入本研究.分别利用频域眼前节OCT和IOLMaster测得角膜中央6mm分17区的角膜厚度、上皮厚度和眼轴长度数据.采用独立样本的t检验比较两组之间的数据差异,同时采用Pearson相关分析对各组年龄、性别与观察数据之间的相关性进行统计分析.结果:高度近视眼组较正常组眼轴增长约4mm(P<0.001).两组之间的上皮厚度之间无明显差异,但是除b5区之外,高度近视眼组的角膜厚度均高于正常组对应的各亚分区.正常组年龄与眼轴长度和上皮厚度呈负相关,而性别与上皮厚度也存在一定的相关性.在高度近视眼组,年龄与上皮厚度呈负相关,同时性别对眼轴和角膜厚度有一定程度的影响.
