We compared the Oculab Tono-Pen, a miniaturized Mackay-Marg tonometer, with a Statham membrane manometer in six humans (12 eyes), three to six hours after death. The intraocular pressure was changed in 5- to 10-mm Hg steps in a range between 0 and 60 mm Hg by an infusion system. The correlation coefficient of the relation of Tono-Pen readings vs manometrically determined intraocular pressures was .99. Compared to the manometer, the Tono-Pen gave a small underestimation of intraocular pressure above 17 mm Hg or overestimation below 17 mm Hg. The maximal deviation of the Tono-Pen readings from the manometer readings was 2.5 mm Hg. In our experience the correspondence between Tono-Pen and manometer readings was superior to the correspondence between the readings obtained with the original Mackay-Marg tonometer and manometry.
我们在六名人类受试者（12只眼睛）死后三至六小时，将小型化的麦凯-马格眼压计（Oculab Tono-Pen）与斯塔瑟姆膜式压力计进行了比较。通过输液系统，在0至60毫米汞柱的范围内，以5至10毫米汞柱的步长改变眼内压。Tono-Pen读数与通过压力测量法测定的眼内压之间关系的相关系数为0.99。与压力计相比，Tono-Pen在眼内压高于17毫米汞柱时会有轻微低估，在低于17毫米汞柱时会有高估。Tono-Pen读数与压力计读数的最大偏差为2.5毫米汞柱。根据我们的经验，Tono-Pen与压力计读数之间的一致性优于原始麦凯-马格眼压计与压力测量法所得读数之间的一致性。
