The purpose of this study was to compare intraocular pressure measurements obtained with XPERT, an upgraded model of the noncontact tonometer, with those from Goldmann applanation tonometry.
An average of three intraocular pressure measurements, generated by the XPERT, was compared with a single reading from a Goldmann applanation tonometer in 421 eyes of 220 patients.
The standard deviation of the matched-pair differences (Sdiff) for the entire population was 2.3 mm Hg, whereas in a subset of 95 eyes with intraocular pressures of > or = 20 mm Hg by Goldmann applanation tonometry, the Sdiff was 3.3 mm Hg.
The XPERT was found to provide reliable intraocular pressure measurements, especially within the normal range.
本研究旨在比较使用非接触眼压计的升级版XPERT测量的眼压与Goldmann压平眼压计测量的眼压。
在220例患者的421只眼中，将XPERT平均测量的三次眼压与Goldmann压平眼压计单次测量的眼压进行比较。
整个人群配对差值的标准差（Sdiff）为2.3 mmHg，而在Goldmann压平眼压计测量眼压≥20 mmHg的95只眼亚组中，Sdiff为3.3 mmHg。
发现XPERT能提供可靠的眼压测量值，尤其是在正常范围内。
