维吾尔族与汉族大学生正视眼生物学测量的对比分析

Comparative analysis of Han and Uygur college students emmetropia biology measurement

目的:观察维吾尔族与汉族大学生正视眼的角膜中央厚度、前房深度、角膜前后表面曲率的差异性,并分析角膜厚度与角膜前后曲率是否有相关性。方法:对新疆医科大学一年级500多名学生进行近视眼筛查,选取正视眼的汉族学生56名和维吾尔族学生51名。应用Sirius角膜地形图对其进行测量。结果:维吾尔族与汉族大学生角膜中央厚度(维:0.53±0.03mm,汉:0.54±0.03mm)、前房深度(维:2.91±0.26mm,汉:3.14±0.25mm)、角膜后表面曲率K2(维:-6.30±0.23D,汉:-6.38±0.28D)有显著性差异(P<0.05)。角膜前表面曲率(K1、K2)及角膜后表面曲率K1无显著性差异(P>0.05)。汉族角膜厚度与角膜前曲率无相关性(r<0),与角膜后曲率亦无相关性(r<1)。维吾尔族角膜厚度与角膜前曲率无相关性(r<0),与角膜后曲率亦无相关性(r<1)。结论:维吾尔族与汉族大学生正视眼的生物学测量指标中,角膜厚度、前房深度及角膜后表面曲率(K2)是有差异的。汉族、维吾尔族的角膜厚度与角膜前、后曲率无明显相关性。

AIM： To observe the differences in central cornea thickness, anterior chamber depth, corneal anterior curvature and corneal posterior curvature between the Uygur and the Han nationality college emmetropia students, and analyze the relationship of corneal thickness and corneal curvature. METHODS： More than 500 students in grade one in Xinjiang Medical University were underwent screening, 56 emmetropia eyes in Han nationality students and 51 in Uygur students were selected. Sirius corneal topography was applied to the measurement. RESULTS： Uygur and the Han nationality college emmetropia students central cornea thickness （ Uygur：0.53±0. 03mm, Han： 0. 54±0. 03mm）, anterior chamber depth （ Uygur： 2. 91±0. 26mm, Han： 3. 14±0. 25mm）, corneal posterior curvature K2 （ Uygur： -6. 30±0. 23D, Han： -6. 38±0. 28D） had significant difference （P〈0. 05）. Corneal anterior curvature （ K1, K2 ） before and corneal posterior curvature K1 there was no significant difference （P〉0. 05）. Han had no significant relationship in corneal thickness and corneal anterior curvature （ r〈0 ） , or in corneal posterior curvature （ r 〈 1 ） . Uygur has no significant relationship in corneal thickness and corneal anterior curvature （r〈0）, or in corneal posterior curvature （r〈1）. CONCLUSION： There are significant differences between the Uygur and the Han nationality college emmetropia students in cornea thickness, anterior chamber depth and corneal posterior curvature K2. There is no significant relationship between corneal thickness and corneal curvature in Uygur and the Han nationality college students.
