摘要
Purpose: To compare the intraocular pressure (TOP) readings taken with the new ICare tonometer and with the Goldmann applanation tonometer (GAT) and to evaluate the influence of central corneal thickness (CCT) on the TOP measurements. Patients and Methods: One eye of 178 consecutive patients with primary open-angle glaucoma underwent ultrasonic CCT measurement, followed by TOP evaluation with the GAT and with the ICare tonometer. The deviation of ICare readings from GAT values, corrected according to the Doughty and Zaman formula, was calculated and correlated to CCT by a linear regression model. The agreement between the 2 devices was assessed by use of the Bland-Altman method. Results: The average CCT was 552 +/- 39 mu m. The mean TOP and the mean corrected TOP with GAT were 19.4 +/- 5.4 mm Hg, and 18.5 +/- 5.7 mm Hg, respectively. The mean ICare TOP reading was 18.4 +/- 5.2 mm Hg. The deviations of ICare readings from corrected GAT values were highly correlated with CCT values (r = 0.63, P < 0.01). Linear regression analysis showed that a CCT change of 10 mu m resulted in an ICare reading deviation of 0.7 mm Hg. The Bland-Altman scatter-plot showed a reasonable agreement between the 2 tonometers. Conclusions: The ICare tonometer can be useful in a routine clinical setting. The TOP readings are quite in accordance with those obtained by GAT. The measurements seemed to be influenced by CCT variations, and thus pachymetry should always be taken into consideration.
