目的 比较非接触眼压计 (non -contacttonometer ,NCT)和Goldmann压平眼压计测量眼压的差异 ,并分别探讨中央角膜厚度 (centralcornealthickniss ,CCT)对这两种测量方法的影响。方法 对 1 0 8例拟接受PRK或LASIK手术的患者行CCT ,NCT和Goldmann压平计眼压测量。结果NCT和Goldmann压平眼压计测得的眼压均值具有显著性差异 (F =89 .70 4 4,P <0 . 0 1 )。CCT与NCT和Goldmann压平眼压计测量值呈正相关 ,相关系数分别是r =0. 4 96 0 (t =8 .356 3,P <0 .0 0 1 )和r =0 . 2 1 1 3(t =3. 1 6 2 3,P <0 .0 0 1 )。结论 NCT和Goldmann压平眼压计测量眼压值有差异 ,NCT测量值大于Goldmann压平眼压计 ,CCT对NCT的影响大于Goldmann压平眼压计。
Objective To compare the differences of intraocular pressure (IOP) between non-contact tonometer (NCT) and Goldmann tonometer, and to investigate the influence of central corneal thickness (CCT) on these two methods. Methods One hundred and eighty patients scheduled for PRK or LASIK underwent CCT, NCT and Goldmann pressure-gage measurements. Results The mean intraocular pressure measured by NCT and Goldmann tonometer were significantly different (F = 89. 70 4 4, P <0.01). There was a positive correlation between CCT and NCT and Goldmann applanation tonometry, the correlation coefficients were r = 0.4960 (t = 8.356, P <0.001) and r = 0.21 3 (t = 3. 1 6 2 3, P <0. 0 0 1). Conclusions The intraocular pressure measured by NCT and Goldmann tonometer is different, the value of NCT is greater than that of Goldmann applanation tonometer, and the effect of CCT on NCT is greater than that of Goldmann applanation tonometer.
