摘要
[目的]对Pentacam系统获得的近视眼的前节各部位数据进行分析.[方法]应用Pentacam系统对436只近视眼球进行检测并获取数据,计算各部位数据的变异系数（Coefficient of variation,CV）.按等效球镜数据,将人群分为超高近视组、高度近视组、中度近视组和低度近视组,数据采用单因素方差分析法（One-way ANOVA）进行分析.按性别分组及眼别分组的数据,采用两独立样本非参数检验法分析（秩和检验）.[结果]眼前部组织和近轴部位数据变化小,前节后部和周边部的数据变化大.超高度近视组的房角,较其他各组的窄,差异有统计学意义（ P ＜0.05）.角膜最薄处厚度、角膜容积和瞳孔直径方面,男性数据与女性数据差异无统计学意义（ P ＞0.05）.左右眼各项数据差异无统计学意义（ P ＞0.05）.[结论]Pentacam系统进行眼部检查,速度快,操作简单,一次检查获取数据功能强,数据结果符合人体解剖特点和生理变化,具有较好的临床应用价值.
[Objective] To analyze the data of ocular anterior segment of myopia eye obtained by Pentacam system. [Methods]The anterior segment of 436 myopia eyes were measured by Pentacam system and the data were obtained. The coefficient of variation（CV） was calculated. According to the data of spherical equivalent（SE）, the subjects were divided into super-high myopia group, high myopia group, moderate myopia group and mild myopia group. One-way ANOVA was used to analyze the data. The data from the groups with different sex or different side of eyes were ana- lyzed by using 2 independent samples tests（rank test）. [Results] The change of the data from anterior tissues and eye tissues near the axis was little, while the change of the data from posterior and periphery tissues was larger. The ante- rior angle in the super-high myopia group was narrower than that in other groups, and there was significant difference （ P〈0.05）. There was no significant difference in thinnest corneal thickness, corneal volume and the diameter of pu- pil between male data and female data（ P 〉0.05）. There was no significant difference in the data between left side and right side of eyes（ P 〉0.05）. [Conclusion] Pentacam system for the examination of eyes is fast, useful and easy to op- erate, and can obtain the data at the first time. The result of the data accords with the characteristics of human anato- my and physiological change. Therefore, Pentacam system has better clinical application value.
