Self-tonometry could be established as an important diagnostic tool in the early diagnosis and follow-up of glaucoma provided that a self-tonometer is precise, safe and easy to use. Furthermore, it has to comply with the legal standards for tonometer calibration. A new software-controlled detection system for the self-tonometer permits the evaluation of external factors during the measurement which influence the precision of the tonometric readings. The updated version of the self-tonometer (ST) was compared to the Draeger hand-held applanation tonometer (HAT) in a clinical study with 82 patients (151 eyes). The results show a regression line characterized by a slope of 0.99, an y interception of 1.41, a correlation coefficient of 0.96 and a standard deviation for the ST readings of +/- 1.78 mmHg. Self-tonometry improves the IOP monitoring as well as patient compliance and therefore is a potential diagnostic tool in the management of glaucoma.
如果自眼压计精确、安全且易于使用，那么自眼压测量法可成为青光眼早期诊断和随访中的一项重要诊断工具。此外，它必须符合眼压计校准的法定标准。一种用于自眼压计的新型软件控制检测系统能够在测量过程中评估影响眼压读数精度的外部因素。在一项针对82例患者（151只眼）的临床研究中，将自眼压计的更新版本（ST）与德尔格手持式压平眼压计（HAT）进行了比较。结果显示，回归线的斜率为0.99，y轴截距为1.41，相关系数为0.96，ST读数的标准差为±1.78 mmHg。自眼压测量法改善了眼压监测以及患者的依从性，因此是青光眼管理中的一种潜在诊断工具。
