In a sample of 212 eyes of patients referred to an ocular pathology clinic, measures of intraocular pressure (IOP) using the non-contact tonometer (NCT) and the Mackay-Marg tonometer were highly correlated (+0.91), the NCT MEASURES BEING LOWER BY AN AVERAGE OF 6.5 MM Hg. In a general optometry clinic, the mean IOP as measured with the NCT on 987 eyes of patients, ages 7 to 85 years, was 15.7 mm Hg (S.D.=3.5 mm Hg). Stability of IOP was age, found for this sample, is unexpected if IOP is proportional to systemic blood pressure which rises with age. Several hypotheses propose to explain the apparent inconsistency.
在转诊至眼科病理诊所的212例患者的212只眼中，使用非接触眼压计（NCT）和麦凯-马格眼压计测量的眼压（IOP）高度相关（+0.91），NCT测量值平均低6.5 mmHg。在一家普通验光诊所，对年龄在7至85岁的987例患者的眼睛使用NCT测量的平均眼压为15.7 mmHg（标准差=3.5 mmHg）。如果眼压与随年龄增长而升高的体循环血压成正比，那么在该样本中发现的眼压稳定性与年龄的关系是出乎意料的。有几种假说试图解释这种明显的不一致。
