To investigate the differences in central corneal thickness (CCT) and curvature in myopic patients with different genders between Mongolian and Han nationalities in the Inner Mongolia region.
Patients with myopia, among whom 122 cases (244 eyes) were Mongolian and 150 cases (300 eyes) were Han, were selected. Pentacam was used to measure the corneal curvature, whereas CCT was determined by Pentacam, Orbscan and ultrasound pachymetry.
Comparisons of the curvature of men and women in Mongolia showed a significant difference (P<0.05) by comparing of the CCT values measured by three methods in Han and Mongolian in Inner Mongolia, we can draw a conclusion that the CCT values measured by Pentacam are less than the values by Orbscan and ultrasound pachymetry, and there are statistically significant difference in CCT measurement among the instruments except between the Orbscan and ultrasound pachymetry. The CCT values of Mongolians are more than Han people, and the analysis exhibited statistical significance. The CCT values measured by Orbscan in Mongolia of women are more than men, the difference showed statistical significance.
Corneal curvature in Mongolian females was significantly higher than that in males. However, no significant difference was observed among Han males and females. The CCT values of Mongolian females were higher than those of males. The normal CCT values measured by Pentacam in Mongolian myopic patients were smaller than those obtained by Orbscan or ultrasound. The normal CCT values of Mongolian patients with myopia were higher than those reported for domestic people.
探讨内蒙古地区蒙古族与汉族不同性别近视患者的中央角膜厚度（CCT）及曲率差异。
选取近视患者，其中蒙古族122例（244眼），汉族150例（300眼）。采用Pentacam测量角膜曲率，用Pentacam、Orbscan及超声测厚仪测定CCT。
蒙古族男女曲率比较差异有统计学意义（P<0.05）。通过比较内蒙古汉族和蒙古族用三种方法测得的CCT值可得出，Pentacam测得的CCT值小于Orbscan和超声测厚仪测得的值，除Orbscan和超声测厚仪之间外，各测量仪器间CCT测量值差异有统计学意义。蒙古族的CCT值高于汉族，分析显示差异有统计学意义。蒙古族女性用Orbscan测得的CCT值高于男性，差异有统计学意义。
蒙古族女性角膜曲率显著高于男性。然而，汉族男女之间未观察到显著差异。蒙古族女性的CCT值高于男性。蒙古族近视患者用Pentacam测得的正常CCT值小于用Orbscan或超声测得的值。蒙古族近视患者的正常CCT值高于国内报道的值。
