AIMS To investigate the effect of central corneal thickness and corneal curvature on intraocular pressure measurements using the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer, and to assess the agreement between the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer in intraocular pressure measurement. METHODS 479 subjects underwent int...

BACKGROUND To compare the intraocular pressure readings obtained with the iCare rebound tonometer and the 7CR non-contact tonometer with those measured by Goldmann applanation tonometry in treated glaucoma patients. DESIGN A prospective, cross-sectional study was conducted in a private tertiary glaucoma clinic. PARTICIPANTS OR SAMPLES One hundred nine (54 males : 55 females) patients includ...

BACKGROUND The purpose of this study was to evaluate the precision of intraocular pressure measurements obtained by PT100 noncontact tonometry in a handheld and slit lamp-mounted position in comparison with that of Goldmann applanation tonometry in healthy young adults. METHODS Sixty eyes from 60 subjects (30 men and 30 women) aged 22 ± 1 (range 20-24) years participated in this study. Tripli...

AIM To evaluate the reliability of the pressure phosphene tonometer in comparison with the Goldmann applanation tonometer. METHODS 45 consecutive patients with glaucoma (78 eyes) participated in the study. Eyes with previous eye surgery, a documented peripheral visual field defect, a refractive error of more than 5 dioptres, and patients who were unable to understand the procedure were exclud...

A clinical evaluation of a new electron ProTon tonometer was performed comparing the values of intraocular pressure (IOP) measured using this instrument with those determined by a similar instrument, Tono-Pen XL, and by Goldmann applanation tonometry. The mean IOP measured in 106 eyes with the ProTon tonometer was not significantly different from that determined with Goldmann applanation, while...

MANY ophthalmologists measure intra-ocular pressure with the Goldmann tonometer. It is neither portable nor capable of being used with the patient supine, which is disadvantageous in glaucoma screening programmes when it is often necessary to examine sick patients in their homes. An applanation tonometer, which is portable and can be used with the patient supine, sitting, or even standing, has ...

Title: Comparison of Intraocular Pressure as Measured by Three Different Non-contact Tonometers and Goldmann Applanation Tonometer for Non-glaucomatous Subjects Authors: Seung Pil Bang ([email protected]) Chong Eun Lee ([email protected]) Yu Cheol Kim ([email protected]) Version: 3 Date: 27 Jul 2017 Author’s response to reviews: Revision Letter Manuscript Number BOPH-D-17-00287 “Comparison of Int...

Background: To analyze the limits of agreement for the intraand inter-session measurements of intra-ocular pressure as measured by the Goldmann applanation tonometer and the Canon TX-F noncontact pulsair tonometer Methods: For this cross sectional study, 138 eyes of 138 cases of age > 16 years with no evidence of glaucomatous changes were recruited. Cases with astigmatism ≥ ±3.0 Diopters, corne...

The accuracy of intraocular pressure measurement with the minified Goldmann applanation tonometer, the pneumatonometer, and the Tono-Pen tonometer were compared in post-mortem human eyes which had undergone penetrating keratoplasty. Enucleated post-mortem human eyes underwent same sized (7.75 mm) or 0.5 mm oversized (8.25 mm) autologous penetrating keratoplasty. Intraocular pressure was then se...
