To evaluate the effectiveness of using a noncontact tonometer (NCT) versus a rebound tonometer (ICare) when measuring the intraocular pressure (IOP) in healthy children.
Prospective observational study.
A total of 180 (96 males and 84 females) healthy children, aged 6 months to 15 years, were recruited. IOPs were measured using both the NCT and ICare devices in the absence of anesthesia. A successful outcome was defined as the measurement of the IOP in both eyes. The McNemar test for comparing correlated proportions was used to analyze the ICare and NCT data.
Although the IOP was successfully measured in 160 children (88.9%) when using ICare, we were only able to successfully measure 130 children (72.2%) when using NCT. Below the age of 6 years, measurement of the IOP using ICare was better tolerated as compared with the NCT (McNemar test; P<0.001). The mean differences (95% limits of agreement) for the IOP readings between ICare and NCT in right and left eyes were 0.90±6.40 and 1.18±6.19 mm Hg, respectively.
IOP measurements performed using ICare are better tolerated in the pediatric population, as compared with measurements using NCT, especially in children below the age of 6 years.
评估在测量健康儿童的眼压（IOP）时，使用非接触眼压计（NCT）与回弹眼压计（ICare）的效果。
前瞻性观察研究。
共招募了 180 名（96 名男性和 84 名女性）健康儿童，年龄在 6 个月至 15 岁之间。在没有麻醉的情况下，使用 NCT 和 ICare 设备测量眼压。成功的结果定义为双眼眼压均成功测量。使用McNemar 检验比较相关比例来分析 ICare 和 NCT 数据。
虽然使用 ICare 成功测量了 160 名儿童（88.9%）的眼压，但使用 NCT 仅成功测量了 130 名儿童（72.2%）的眼压。在 6 岁以下儿童中，与 NCT 相比，ICare 测量眼压的耐受性更好（McNemar 检验；P<0.001）。右眼和左眼的 ICare 和 NCT 眼压读数之间的平均差异（95%置信区间）分别为 0.90±6.40 和 1.18±6.19mmHg。
与 NCT 相比，ICare 在儿科人群中的眼压测量更耐受，尤其是在 6 岁以下的儿童中。
