A comparison of intraocular pressure (IOP) in cases of infantile glaucoma during general anesthesia was carried out by measurement with the iCare rebound tonometer (RBT) and a handheld applanation tonometer (Perkins).
A total of 45 eyes from pediatric patients with childhood glaucoma were included in this prospective trial. Bland-Altman plots and linear regression were used for statistical analysis.
In almost two thirds of the eyes the difference between RBT and Perkins was 2 mmHg or less. A systemic bias of 1.96 mmHg and a 95% confidence interval of -3.35 to 7.26 was detected. Linear regression of the Bland-Altman data showed a proportional error (gradient=0.16; r(2)=0.23; p<0.01).
The iCare rebound tonometer is useful during general anesthesia in cases of childhood glaucoma. It provides comparable IOP values to applanation tonometry with a tendency to record higher values.
通过使用iCare回弹眼压计（RBT）和手持式压平眼压计（帕金斯眼压计）测量，对小儿青光眼患者在全身麻醉期间的眼压（IOP）进行了比较。
本前瞻性试验纳入了45只患有儿童青光眼的儿科患者的眼睛。采用Bland-Altman图和线性回归进行统计分析。
在几乎三分之二的眼睛中，RBT和帕金斯眼压计之间的差异为2 mmHg或更小。检测到系统性偏差为1.96 mmHg，95%置信区间为-3.35至7.26。Bland-Altman数据的线性回归显示存在比例误差（斜率=0.16；r²=0.23；p<0.01）。
iCare回弹眼压计在小儿青光眼全身麻醉期间有用。它提供的眼压值与压平眼压测量法相当，且有记录更高值的趋势。
