哈萨克族与汉族大学生正视眼生物学测量的对比分析

Comparative analysis of emmetropia biology measurement in Han and Kazak college students

目的:观察哈萨克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、后曲率的相关性。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55名和哈萨克族学生51名,应用Sirius角膜地形图对其进行测量。结果:哈萨克族与汉族大学生角膜中央厚度(哈:0.52±0.03mm,汉:0.54±0.03mm)、前房深度(哈:2.97±0.31mm,汉:3.14±0.25mm)有显著性差异(P<0.05)。角膜前、后表面曲率(K1,K2)无显著性差异(P>0.05)。汉族的角膜厚度与角膜前曲率相关分析r<0,与角膜后曲率相关分析r<0.1。哈萨克族的角膜厚度与角膜前曲率相关分析r<0,与角膜后曲率相关分析r<0.1。结论:哈萨克族与汉族大学生正视眼的生物学测量指标中,角膜厚度、前房深度是有差异的。两个民族的角膜厚度与角膜前、后曲率(K1,K2)无相关性。

AIM： To observe the differences of central cornea thickness, anterior chamber depth, corneal anterior curvature and corneal posterior curvature between the Kazak 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 for screening, selected 55 emmetropia eyes in Han nationality students and 51 in Kazak students. Sirius corneal topography was applied to the measurement.RESULTS： Kazak and the Han nationality college emmetropia students’ central cornea thickness（ Kazak：0. 52 ± 0. 03 mm,Han： 0. 54 ± 0. 03mm）,anterior chamber depth（ Kazak： 2. 97 ± 0. 31 mm,Han： 3. 14 ± 0. 25mm） had significant difference（ P 〈 0. 05）. Corneal anterior curvature and corneal posterior curvature were 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 〈 0. 1）. Kazak had no significant relationship in corneal thickness and corneal anterior curvature（ r 〈0）,or in corneal posterior curvature（ r 〈0.1）.CONCLUSION： There are significant differences between the Kazak and the Han nationality college emmetropia students in cornea thickness, anterior chamber depth. There is no significant relationship between corneal thickness and corneal curvature（ K1,K2）in Kazak and the Han nationality college emmetropia students.
