To confirm the accuracy of the Pulsair 3000 before introducing the instrument into clinical practice.
A masked study by two experienced tonometrists comparing the mean of the Goldmann intraocular pressure (IOP) readings against the Pulsair 3000 reading (average of four puffs). Results of 150 eyes were compared with an IOP range of 10 mm Hg-44 mm Hg.
Correlation between the two Goldmann tonometry results was 0.9830 with a standard deviation of 1.1085 mm Hg. Correlation between the mean of the two Goldmann readings against the Pulsair 3000 reading was 0.982 with a standard deviation of 1.1179 mm Hg. Bland-Altman analysis confirms a satisfactory outcome.
The Pulsair 3000 provides an accurate and objective method of measuring IOP with many advantages over traditional Goldmann tonometry.
在将Pulsair 3000仪器引入临床实践之前,确认其准确性。
由两名经验丰富的眼压测量师进行一项盲法研究,比较Goldmann眼压(IOP)读数的平均值与Pulsair 3000读数(四次吹气的平均值)。将150只眼睛的结果与10毫米汞柱至44毫米汞柱的眼压范围进行比较。
两次Goldmann眼压测量结果之间的相关性为0.9830,标准差为1.1085毫米汞柱。两次Goldmann读数的平均值与Pulsair 3000读数之间的相关性为0.982,标准差为1.1179毫米汞柱。Bland-Altman分析证实结果令人满意。
Pulsair 3000提供了一种准确、客观的眼压测量方法,与传统的Goldmann眼压测量法相比有许多优点。
