Comparison of Rebound and Applanation Tonometry in Eyes With Focal Corneal Edema. [PDF]

Vet Ophthalmol
ABSTRACT Objective To determine the effect of corneal edema on intraocular pressure (IOP) readings and their accuracy and precision when obtained with handheld rebound and applanation tonometers. Animals and Procedures IOP readings from areas of focal corneal edema were compared to those from clear cornea in 10 eyes of 7 glaucomatous cats in vivo using

Goldmann Tonometry and Corneal Biomechanics

Applied Sciences, 2021
Glaucoma is the second cause of irreversible blindness in the world. Intraocular pressure (IOP) is a recognized major risk factor for the development and progression of glaucomatous damage. Goldmann applanation tonometry (GAT) is internationally accepted

Systematic Review of the Agreement of Tonometers with Goldmann Applanation Tonometry [PDF]

Ophthalmology, 2012
To assess the agreement of tonometers available for clinical practice with the Goldmann applanation tonometer (GAT), the most commonly accepted reference device.A systematic review and meta-analysis of directly comparative studies assessing the agreement of 1 or more tonometers with the reference tonometer (GAT).A total of 11 582 participants (15 525 ...

Comparison of Dynamic Contour Tonometry with Goldmann Applanation Tonometry

Investigative Opthalmology & Visual Science, 2004
The dynamic contour tonometer (DCT; Pascal tonometer) is a novel tonometer designed to measure intraocular pressure (IOP) independent of corneal properties. The purpose of this study was a comparison of the DCT with the Goldmann applanation tonometer (GAT) with respect to mean of IOP readings, the influence of ocular structural factors on IOP readings,

Reutilization of disposable rebound tonometer probes: Risk or return?

Indian Journal of Ophthalmology, 2023
Purpose: An advantage of rebound tonometry (RT) is its ease of use so that it can also be operated by health care technicians. However, the cost of the disposable measuring probes is high and their reuse carries the risk of infection.

Goldmann applanation tonometry after myopic photorefractive keratectomy [PDF]

Acta Ophthalmologica Scandinavica, 1998
To determine the accuracy of applanation tonometry in patients with corneas thinned by photorefractive keratectomy, and to correlate corneal changes with tonometric readings.The intraocular pressure was measured with Goldmann applanation tonometry in 87 patients who underwent photorefractive keratectomy before and 1, 6 and 12 months after treatment ...

Intraocular pressure and ocular pulse amplitude using dynamic contour tonometry and contact lens tonometry

BMC Ophthalmology, 2004
Background The new Ocular Dynamic Contour Tonometer (DCT), investigational device supplied by SMT (Swiss Microtechnology AG, Switzerland) allows simultaneous recording of intraocular pressure (IOP) and ocular pulse amplitude (OPA). It was the aim of this

A Mathematical Model of the Goldmann Applanation Tonometry

, 2022
Abstract The aim of this study is to present mathematical formulas describing all forces involved in Goldmann applanation tonometry to calculate the measurement error of the true intraocular pressure as a function of the surface tension of the tear film, the corneal modulus of elasticity, the corneal thickness and the average apical corneal ...

Accuracy of Schiotz Tonometry in Measuring the Intraocular Pressure After Corneal Refractive Surgery

Journal of Optometry, 2008
Purpose: To test the accuracy of Schiotz tonometry (ST) in patients that underwent photorefractive keratectomy (PRK). Methods: 175 eyes previously treated with PRK for myopia, myopic astigmatism or mixed astigmatism, with a mean preoperative spherical ...
