To study if the Tono-Pen, a hand held digital tonometer, can replace Schiøtz tonometry in general practice.
Tonometry with Tono-Pen and Schiøtz tonometer were compared.
Group practice with two general practitioners (GPs).
48 consecutive patients over 40 years of age.
The mean difference between intra ocular pressure (IOP) measured with the two methods with 95% confidence intervals and 95% limits of agreement between them.
One observer found a mean difference between methods of 0.3 mmHg and 95% limits of agreement of +/- 4 mmHg. The other observer with a different Schiøtz tonometer, had a mean difference of approximately -2 mmHg and 95% limits of agreement from -8 to +4 mmHg.
We consider the Tono-Pen to be an alternative to Schiøtz tonometry. The maximum mean difference between the methods for one GP, 1.9 mmHg, was within clinically acceptable limits. Possible reasons for the different agreement for the two observers are discussed.
研究手持式数字眼压计Tono - Pen在全科医疗中能否取代施眼压计测量眼压。
对比使用Tono - Pen和施眼压计测量眼压。
由两名全科医生（GP）坐诊的联合诊所。
48名连续入选的40岁以上患者。
两种方法测量眼内压（IOP）的平均差值及95%置信区间，以及二者之间95%的一致性界限。
一名观察者发现两种方法的平均差值为0.3 mmHg，95%一致性界限为±4 mmHg。另一名观察者使用不同的施眼压计，平均差值约为 - 2 mmHg，95%一致性界限为 - 8至 + 4 mmHg。
我们认为Tono - Pen可作为施眼压计测量眼压的替代方法。一名全科医生测量的两种方法之间的最大平均差值为1.9 mmHg，在临床可接受范围内。文中讨论了两名观察者一致性不同的可能原因。
