Frequency of Goldmann Applanation Tonometer Calibration Error Checks

Journal of Glaucoma, 2005
To investigate how quickly Goldmann applanation tonometers used in clinical practice develop calibration errors, and to determine the frequency of checks required to detect these errors.Prospective check of the calibration error of all Haag-Streit Goldmann applanation tonometers in the department at month zero, month one, and month four. The tonometers

Comparison of Rebound Tonometer and Goldmann Handheld Applanation Tonometer in Congenital Glaucoma

Journal of Glaucoma, 2009
To compare intraocular pressure (IOP) measurements obtained using the rebound tonometer (RBT) and the handheld Goldmann applanation tonometer (Perkins) in children with congenital glaucoma.Using both tonometers, the IOP was prospectively determined in 68 eyes of 68 patients with congenital glaucoma aged 3 to 13 years. Corneal curvature, central corneal

The Outcomes of a Comprehensive Program for Maintenance of Goldmann Applanation Tonometer

Journal of Glaucoma, 2019
Precis: We checked 190 tonometers every month and repaired faulty ones. Calibration error (CE) frequency reduced from 23% to 0.6% at 1 year. Tonometers needing one or >1 CE repair differed in survival but not in age. Purpose: The purpose of this study was to report the outcomes ...

Comparison of ocular response analyzer, dynamic contour tonometer and Goldmann applanation tonometer

International Ophthalmology, 2010
The aim of this study was to compare the intra-ocular pressure (IOP) obtained by ocular response analyzer (ORA), dynamic contour tonometer (DCT) and Goldmann applanation tonometer (GAT). In 102 patients (47 with primary open-angle glaucoma and 55 healthy controls) IOP was measured with GAT, ORA and DCT in one eye. The agreement between GAT, DCT and ORA

Comparison of the Transpalpebral Tonometer TGDc-01 with Goldmann Applanation Tonometry

European Journal of Ophthalmology, 2010
Purpose This study aimed to compare intraocular pressure (IOP) measurements obtained by the transpalpebral tonometer TGDc-01 and by the Goldmann applanation tonometer (GAT). Methods IOP was measured by the conventional GAT and the TGDc-01 tonometer. Central corneal thickness (CCI) was measured for all eyes. Results Sixty-seven consecutive patients (123

Reliability of proton and goldmann applanation tonometers in normal and postkeratoplasty eyes

Ophthalmology, 2002
To compare the reliability of intraocular pressure (IOP) measurements with the ProTon tonometer and the Goldmann applanation tonometer (GAT) in normal and post-penetrating keratoplasty (post-PK) eyes.Prospective, nonrandomized, comparative case series.Twenty-four individuals (48 eyes) with no known ocular disorder and 59 patients (59 eyes) that had ...

Comparison of the Icare Tonometer and the Hand-held Goldmann Applanation Tonometer in Pediatric Aphakia

Journal of Glaucoma, 2013
To compare the intraocular pressure (IOP) measurements obtained by the Icare and the hand-held Goldmann applanation tonometer (also called Perkins) in aphakic children after congenital cataract surgery.We investigated 125 children with aphakia after congenital cataract surgery in this study. A younger group (3 to 30 mo) and an elder group (31 to 72 mo)

Clinical Comparison of the Oculab Tono-Pen to the Goldmann Applanation Tonometer

Ophthalmology, 1987
The Oculab Tono-Pen tonometer was compared with the Goldmann applanation tonometer through studies on 197 eyes of 103 patients with glaucoma or ocular hypertension to evaluate the reliability of the Tono-Pen in determining intraocular pressure (IOP). Patients were randomized into four groups and all applanations were done by the same investigator.
