Comparison of Three Different Techniques of Intraocular Pressure Measurement by Non-Contact Tonometer, Goldmann Applanation Tonometer and Icare Rebound Tonometer
Abstract: Background: In daily ophthalmic procedures measurement of intraocular pressure is essential for glaucoma screening. Factors such as central corneal thickness and corneal rigidity can influence the accuracy of IOP measurement. The purpose of the study is to evaluate the accuracy and reliability of rebound tonometer, non-contact tonometer and Goldmann applanation tonometer and also to compare their IOP measurements obtained by those with the Goldmann applanation tonometer. Methods: In 200 eyes of 101 subjects, the intraocular pressure measurements were sequentially obtained by Topcon-CT800 non-contact tonometer, Goldmann applanation tonometer, iCare IC100 rebound tonometer respectively. Central corneal thickness was measured using SP-300P specular microscope. Pearson correlation and interclass correlation analysis were performed for evaluating the IOP measurement agreement among the tonometers. The influence of CCT on each IOP measurement methods was evaluated by linear regression analysis. Results: A significant strong positive correlation of p value
