摘　　要：目的:了解广西壮族近视人群角膜中央厚度、眼压、角膜曲率等特征,并与同一地区汉族近视人群进行比较,了解壮族、汉族人群眼部数据有无差异。方法:连续记录测量499例990眼壮族及772例1538眼汉族近视眼患者角膜中央厚度、眼压、角膜曲率、屈光度及年龄、性别,并进行分析。结果:壮族人群平均角膜中央厚度(CCT)为(533.23±29.63)μm,男性为(537.04±29.33)μm,女性为(529.56±29.66)μm;平均眼压值(IOP)(15.86±2.45)mmHg,男女分别为(15.94±2.67)mmHg和(15.71±2.45)mmHg;平均角膜曲率(keratom etry)为(43.35±1.16)D,男、女性分别为(42.99±1.30)D和(43.91±1.38)D。男性CCT明显较女性厚,父母亲均为壮族者角膜中央厚度较父母亲一方为壮族者要薄。与汉族人群相比,壮族人群CCT较汉族人群薄约10μm(t=5.893,P=0.000)。结论:壮族近视人群角膜中央厚度和眼压测量值较汉族人低,临床诊治和行角膜屈光手术时应予注意。Objective：To study central corneal thickness（CCT）,refractive status,keratometry and intraocular pressure（IOP） measurements on Myopia patients of Zhuang Ethnic people and to search for possible associations between CCT and patient＇s Ethnic,age,sex,and comparison with Han Ethnic people.Methods： 499 cases （990 eyes） of Zhuang and 772 cases（1538 eyes） of Han patients with myopia were included in the study.Patient＇s age,sex,CCT,refractive status,keratometry, and IOP were obtained together with Ethnic of the patients and their parents.Main outcome measures were CCT measurements and relationship between CCT and patient＇s Ethnic.Results： The CCT,IOP,keratometry of Zhuang Ethnic were（533.23±29.63）μm,（15.86±2.45）mmHg and（43.35±1.16）D.Patients of Zhuang Ethnic had statistically significantly thinner corneas than patients of Han Ethnic（533.23±29.63）μm vs（544.53±32.58）μm（t=5.893,P=0.000）.Patients of Zhuang Ethnic had statistically significantly lower IOP than patients of Han Ethnic（P=0.016）.No differences were found when comparing age,sex,refractive status,and keratometry.Conclusions： This is the first work in reporting CCT in people of Zhuang Ethnic.Patients of Zhuang Ethnic had thinner corneas and lower IOP than patients of Han Ethnic.Studies from similar populations are needed to confirm our results.
