作为一项基于人群的流行病学研究的一部分，对Goldmann压平眼压计测量眼内压（IOP）的重现性进行了研究。在第一次测量会议中检查了62名受试者。根据固定方案，在双眼中连续测量IOP三次。这些测量值的平均标准差（SD）为0.8 mmHg。首次测量的平均观察者内变异为1.64（SD 2.07）mmHg。对于三次测量的中位数，观察者内变异为1.50（SD 1.96）mmHg。首次测量的平均观察者间值为1.79（SD 2.41）mmHg，中位测量值为1.60（SD 2.15）mmHg。两名观察员的三次测量的中位数之间的相关系数为0.81。两个观察者之间没有发现系统性差异。与单次测量相比，使用三次连续测量的中位数将观察者间变异减少了11%，观察者内变异减少了9%。
The reproducibility of intraocular pressure (IOP) measurement with the Goldmann applanation tonometer was investigated as part of a population-based epidemiological study. Sixty-two subjects were examined in a first measurement session. The IOP was measured three times consecutively in both eyes according to a fixed protocol. The mean standard deviation (SD) of these measurements was 0.8 mmHg. The mean intra-observer variation for the first measurement was 1.64 (SD 2.07) mmHg. For the median of the three measurements the intra-observer variation was 1.50 (SD 1.96) mmHg. The mean inter-observer values were 1.79 (SD 2.41) mmHg for the first measurement and 1.60 (SD 2.15) mmHg for the median measurement. The correlation coefficient between the median values of the three measurements of both observers was 0.81. No systematic differences were found between the two observers. Using the median value of three consecutive measurements reduced the inter-observer variation by 11% and the intra-observer variation by 9% compared with a single measurement.
