摘　　要：目的:用Tono-Pen眼压计测量人眼角膜中央、旁中央、角巩缘部位眼压值,比较不同部位值的差异及相关性。方法:正常角膜用Tono-Pen眼压计依次测量角膜中心、旁中心、角膜缘眼压值,方差分析不同部位眼压的差异,分析结果的相关性。结果:Tono-Pen眼压计检测得出的眼压平均值角膜中央为16.28±2.73mmHg,旁中央为16.33±2.69mmHg,角巩缘为16.58±2.58mmHg.角膜中心与旁中心的相关系数r=0.966,P=0.000,角膜中心与角膜缘的相关系数为r=0.897,P=0.000,角膜旁中心与角膜缘的相关系数为r=0.910,P=0.000。不同部位眼压值差异没有显著性(F=0.093,P=0.913>0.05)。结论:不同部位眼压值密切相关,差异没有统计学意义。Tono-Pen眼压计测量不同部位眼压均可取得较为一致的结果。AIM： To explore the difference and correlation of the intraocular pressures （IOP） at different points in human＇s cornea measured by Tono-Pen tonometer. METHODS： The IOP were measured by Tono-Pen tonometer at central cornea, pericentral cornea and corneoscleral limbus. Analysis of variance and linear correlation were used respectively to evaluate the difference and correlation of IOP at different points of cornea. RESULTS： The IOP obtained from central cornea, pericentral cornea and corneoscleral limbus by Tono-Pen tonometer were 16.28±2.73mmHg, 16.33±2.69mmHg and 16. 58±2. 58mmHg respectively. There was significant correlation between the IOP at central cornea and at pericentral cornea （r=0.966, P=0.000）; while the correlation coefficient between IOP at central cornea and at corneal limbus was 0.897 （ P=0.000）, and the correlation coefficient between IOP at pericentral cornea and at corneal limbus was 0. 910 （P=0.000）. There was no statistical difference between the IOP obtained from different points of cornea （F=0.093, P=0.913 〉0,05）. CONCLUSION ： Consistent IOP values could be obtained from different points of cornea by Tono-Pen tonometer, and there was significant correlation and no statistical difference with between IOP at different locations of cornea.
