The measurement of intraocular pressure with a noncontact tonometer was correlated to a Goldmann tonometer in 20 normal persons, 20 glaucomatous patients, and 8 patients suffering from corneal diseases. In normal persons the error in measurement for the noncontact tonometer was related to their skill in fixation, and in eye patients to height of pressure and corneal state. Acceptable correlation was found between noncontact tonometry and Goldmann applanation tonometry when the cornea was normal and the pressure below 35 mmHg (Goldmann), otherwise noncontact tonometry was only a guide, and in the presence of corneal disease, unreliable. Good fixation reduced the method error. The standard deviation was 1.09 mmHg at poor fixation and 0.60 mmHg at good fixation. Repeated measurements on the same eye with noncontact tonometry did not alter the intraocular tension.
在20名正常人、20名青光眼患者和8名患有角膜疾病的患者中，使用非接触眼压计测量眼压，并与戈德曼眼压计进行对比。在正常人中，非接触眼压计的测量误差与他们的注视技巧有关，而在眼科患者中，测量误差与眼压高度和角膜状态有关。当角膜正常且眼压低于35 mmHg（戈德曼眼压计测量值）时，非接触眼压测量法与戈德曼压平眼压测量法之间存在可接受的相关性；否则，非接触眼压测量法仅作为一个参考，并且在存在角膜疾病时不可靠。良好的注视可减少方法误差。注视不佳时标准差为1.09 mmHg，注视良好时为0.60 mmHg。对同一只眼睛重复进行非接触眼压测量不会改变眼压。
