摘要: PURPOSE To compare the intraocular pressure (IOP) measurements obtained with rebound tonometer (RT) and Goldmann handheld (GT) in normal altered corneas. METHODS A total of 208 corneas 50 pathologies were included this prospective study. All randomly by 1 observer. The medians interquartile range (IR) for both tonometers compared. median differences assessed IOP groups. Agreement between was calculated using Bland-Altman method. RESULTS all eyes 17 mm Hg (IR, 13-22 Hg) RT 16 13-21 GT (P < 0.001). correlation excellent (r2 = 0.86; P minimal two from 10 to 20 (GT). scatterplot good agreement instruments. In corneas, difference or =2 77.4% cases. 73% cases 0.21 compared group). 10% 2% cases, could not be measured RT, respectively. CONCLUSIONS results similar tonometers. difficult obtain because distorted half-circles. 1-mm-diameter disposable tip facilitated obtaining without anesthetic drops, which avoids infections. useful routine clinical settings when measuring pathologies.
