Clinical use of a new position-independent rebound tonometer.

摘要: Purpose:To compare intraocular pressure (IOP) measurements obtained by rebound tonometry (Icare PRO tonometer), applanation (Goldmann and Perkins tonometry), dynamic contour in the upright supine positions, to investigate influence of axial length central corneal thickness.Methods:Ninety-nine right eyes 99 patients with glaucoma or suspect for glaucoma, admitted our department between November 2010 January 2011 obtain an IOP profile including measurements, were included study. position using Icare (RTPRO), a Goldmann (GAT), Pascal tonometer (DCT). In position, taken RTPRO hand-held (PAT). The means SDs all tonometers compared. Agreement was calculated Bland-Altman method.Results:The mean IOPs 17.78.0 mm Hg 17.6 +/- 7.8 19.9 6.6 Correlation analysis these data indicated good correlation readings GAT (r=0.951; P<0.001), DCT (r=0.897; P<0.001). revealed differences (bias) GAT, 0.1 -1.8 Hg, 95% limits agreement -3.6 3.8 -7.3 3.6 respectively. 19.2 6.4 19.6 6.2 PAT.Conclusions:Measurements RTPRO, either show those provided tonometry. study registered DRKS (German Clinical Trials Register; http://www.germanctr.de; DRKS00000581).
