The differences between two careful applanation tonometries performed by one and by two observers, respectively, were compared. Two measurements by one observer differed by 2 mmHg or more in 8% of the pairs of measurements and by 3 mmHg or more in 2% of the pairs. One tonometry each by two observers differed by 2 mmHg or more 40% of the pairs of measurement and by 3 mmHg or more in 17% of the pairs. There was no dependence on the intraocular pressure. Possible reasons for the increase in variance are discussed.
分别比较了由一名观察者和两名观察者进行的两次仔细压平眼压测量之间的差异。一名观察者进行的两次测量中，8%的测量对相差2 mmHg或更多，2%的测量对相差3 mmHg或更多。两名观察者各自进行的一次眼压测量中，40%的测量对相差2 mmHg或更多，17%的测量对相差3 mmHg或更多。这种差异与眼压无关。文中讨论了方差增加的可能原因。
