Purpose: To evaluate the effectiveness of using a noncontact tonometer (NCT) versus a rebound tonometer (ICare) when measuring the intraocular pressure (IOP) in healthy children. Design: Prospective observational study. Methods: 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. Results: 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 (plus or minus) 6.40 and 1.18 (plus or minus) 6.19 mm Hg, respectively. Conclusion: 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.
