不同年龄正常人群眼前节参数的分析

Analysis of normal eye anterior segments in different ages

目的使用新一代眼前节分析和诊断设备Pentacam对正常眼进行测量和统计学分析。方法对221名正常人(442眼)进行Pentacam检查,人群分为5个年龄组,其中40岁以下50名(100眼);40～49岁50名(100眼);50～59岁50名(100眼); 60～69岁50名(100眼);70及70岁以上21名(42眼)。结果随着年龄增长,各年龄组之间前房容积、虹膜角膜角(前房角)和前房深度比较差异有统计学意义(P<0.05)。高年龄组中,前房参数在性别间差异有统计学意义(P<0.01)。结论眼前节各参数与年龄因素有显著相关性。男女性别之间前房参数的差异大多出现在60岁之后。

Objective To measure and conduct statistic analysis of normal eyes by Pentacam. Methods Two hundred and twenty-one healthy people （442 eyes） underwent examinations of Pentacam, and they were divided into 5 groups by age： 〈40 years old group （50 people, 100 eyes）, 40-49 years old group （50 people, 100 eyes）, 50-59 years old group （50 people, 100 eyes）, 60-69 years old group （50 people, 100 eyes） and 〉70 years old group （21 people, 42 eyes）. Results With the increase of age, there were significant differences in chamber volume, chamber angle and anterior chamber depth among age groups （P 〈 0.05） In elder age groups, there were significant differences in these parameters between males and females （P 〈 0.01）. Conclusion Anterior segment parameters are significantly correlated with age. After 60 years old, the anterior segment parameters become significantly different with gender.
