摘要
目的比较非接触式眼压计（NCT）与Goldmann压平眼压计（GAT）在正常人群及高眼压人群中测量值的差异，并观察比较中央角膜厚度（CCT）对两种眼压计的影响。方法前瞻性临床对比研究。按就诊次序随机选取80例门诊患者共91只眼行CCT、NCT和GAT测量。结果NCT测量值比GAT测量值偏高，且两者测量值差异有统计学意义（F=69．600，P〈0．01），CCT对NCT的影响比GAT偏大，相关系数分别是n=0．742（P〈0．05）和n=0．663（P〈D．05）。结论NCT测量值与GAT测量值有差异，NcT测量平均值比GAT测量平均值偏高，眼压值越高，两者的差异越大；两种眼压计均受CCT的影响，CCT值越大眼压值也越高，且其对NCT的影响大于GAT。
ObJective To compare the difference of Goldmann applanation tonometer （GAT） and non-contact tonometer （NCT） in IOP measurement, and to observe the change of IOP influenced by center corneal thickness （CCT）. Methods Central corneal thickness, IOP measured by NCT and Goldmann applanation tonometer were measured on total of 91 eyes of 80 cases. Result There was significant difference between IOP measured by NCT and IOP by Goldmann applanation tonometer （F =69, 600, P 〈0.01）, the IOP measured by NCT was higher than GAT, the relative data r1= 0.742 （P 〈0.05） and r2=0.663 （P 〈0.05）, so the influence of CCT on NCT was larger than GAT. Conclusions There are differences between IOP measured by NCT and IOP by Goldmann aplana- tion tonometer. IOP measured by NCT is higher than which measured by Goldmann aplanantion tonometer. Both of the two tonometers are influenced by the CCT, and it is larger with the increasing of the CCT. The influence of CCT on the measurements of intraocular pressure with NCT is higher than Golamann aplanation tonometer.
