摘　　要：目的比较Pentacam、OrbscanⅡ和A超三种角膜测厚仪检测近视眼中央角膜厚度的差异。方法分别用Pentacam眼前节分析仪、OrbscanⅡ角膜地形图仪及A超对角膜厚度进行检测,并将测量值进行统计学分析。结果 Pentacam测得角膜厚度为(536.01±32.33)μm,OrbscanⅡ测得近视眼角膜厚度为(539.21±37.45)μm,A超测得角膜厚度为(535.39±31.46)μm。OrbscanⅡ测量值与Pentacam和A超测量值差异均有统计学意义(P<0.001),Pentacam与A超测量值间的比较差异无统计学意义(P=0.095)。三种测厚结果显示高度正相关,Orb-scan-Pentacam、Orbscan-A超、Pentacam-A超的相关系数r分别为0.917、0.906、0.965,回归方程如下:Orbscan(μm)=-30.699+[1.062 2×Pentacam(μm)],Orbscan(μm)=-38.599+[1.079 2×A超(μm)],Pen-tacam(μm)=5.424+[0.991 9×A超(μm)]。结论在检测中央角膜厚度方面,OrbscanⅡ与Pentacam及A超不可替代使用,Pentacam与A超可相互替代使用。Objective To compare the central corneal thickness measurements using pentacam, orbscan II and A-ultrason- ic pachymeter in myopic eyes. Methods Central corneal thickness was measured and analyzed with pentacam, orbscan lI, and A-ultrasonics. Results The mean central corneal thickness measured by pentacam, orbscan II, and A-ultrasonics were （536.01 ±32.33） p,m, （539.21 ±37.45） μm,and（535.39 ±31.46） μm,respectively. Significant difference was found between orbscan II and pentacam or A-ultrasonic （ P 〈 0.001 ）. No significant difference was found between pen- tacam and A-ultrasonic （P = 0.095 ）. Positive relationships were found in the results of corneal thickness among the 3 methods. The correlation coefficient r of （ orbscan-pentacam）, （ orbscan-A-ultrasonic）, （pentacam-A-ultrasonic） were correpondinging 0. 917,0.906, and 0. 965. The regression equations were ＂orbscan （μm） = - 30. 699 ± [ 1. 062 2 × pentacam（μm） ] ＂, ＂orbscan（μm） = - 38. 599 ± [ 1. 079 2 × A-ultrasonic （μm） ] ＂, and ＂pentacam（μm） = 5. 424 ± [ 0. 991 9 × A-ultrasonic （μm）] ＂. Conclusion For central corneal thickness, pentacam is superior to A-ultrasonic, but orbscan/pentacam and orbscan/A-ultrasonic are not substitutable for each other.
