摘要:
目的　统计天津市人群中kappa角的分布，并比较iTrace像差仪和 Pentacam眼前节分析仪所测量的kappa角差异。方法　采用回顾性研究分析。收集2014年至2016年在天津医科大学眼科医院行iTrace像差仪测量4815人4815眼所获得的kappa角，并选出同时经iTrace像差仪和Pentacam眼前节分析仪测量的1031人1031眼，比较两种仪器测量kappa角差异。结果　iTrace像差仪测量的kappa角为（0.47±0.48）mm，其中kappa角小于0.50 mm者占70.07%。不同性别之间kappa角差异无统计学意义（P=0.090）；左眼的kappa角大于右眼，差异也有显著统计学意义（P=0.000）。kappa角大小和年龄相关但相关性不大（r=0.129，P<0.05）。iTrace像差仪和Pentacam眼前节分析仪测量的kappa角比较差异有显著统计学意义（P=0.000），后者测量的结果显著小于前者。结论　人群中kappa角呈非正态分布且大部分小于0.50 mm；iTrace像差仪和Pentacam眼前节分析仪测量的kappa角有显著差别，且前者大于后者。
Abstract:
Objective　To explore the distribution of the kappa angles in population of Tianjin，China and the differences in kappa angle measured by iTrace and Pentacam.Methods　A retrospective research was conducted.The kappa angle of 4815 patients （4815 eyes） and kappa angle was measured and recorded through iTrace from June 2014 to December 2016 in Tianjin Medical University Eye hospital and meanwhile，the kappa angle of 1031 eyes selected from the total sample was also measured with pencatam.Results　The kappa angle was （0.47±0.48）mm，and patients with kappa angle <0.50 mm accounted for 70.07%.There was no significant difference in kappa angle of different genders （P=0.090）.Right eyes had larger kappa anger than left eyes，approaching significant difference （P=0.000）.Kappa anger was slightly correlated with age （r=0.129，P<0.05）.And kappa angle measured by iTrace was significantly smaller than that measured by Pentacam （P=0.000）.Conclusion　The kappa angle in the population is non-normal and most of them are less than 0.5 mm.There is significant difference between the kappa angle measured by iTrace and pentacam.
