Abstract

The aim of the study was to assess agreement between two commercially available applanation tonometers for the measurement of intraocular pressure (IOP). Forty subjects underwent IOP measurement on two accurately calibrated Goldmann type applanation tonometers (Zeiss AT 030 (GATZ) and Inami L-5110(GATI)). The order of examination was randomized and observers were masked to the IOP recorded. The mean of two consecutive readings, from a randomly selected eye for each subject, was used for analysis. Agreement was assessed using the Altman and Bland plot. The mean (SD) IOP readings on GATZ was 15.32 (+/-6.80) mm Hg and on GATI was 13.52 (+/-5.65) mm Hg (p< 0.001, 95% CI of the difference: -2.48 to -1.11). The 95% limits of agreement on the Altman and Bland plot were:-2.47 to 6.16 mm Hg). There was significant inter-instrument variability between the two accurately calibrated Goldmann type applanation tonometers studied.

摘要

本研究的目的是评估两种市售压平眼压计在测量眼压（IOP）方面的一致性。40名受试者在两台精确校准的戈德曼型压平眼压计（蔡司AT 030（GATZ）和饭美L - 5110（GATI））上进行眼压测量。检查顺序是随机的，观察者对记录的眼压情况不知情。对每个受试者随机选择一只眼睛的连续两次读数的平均值进行分析。使用奥特曼和布兰德图评估一致性。GATZ上的眼压读数平均值（标准差）为15.32（±6.80）mmHg，GATI上为13.52（±5.65）mmHg（p<0.001，差异的95%置信区间：-2.48至-1.11）。奥特曼和布兰德图上的95%一致性界限为：-2.47至6.16 mmHg。在所研究的两台精确校准的戈德曼型压平眼压计之间存在显著的仪器间变异性。
