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

open access: yesBMC 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 mechanical model of ocular bulb vibrations and implications for acoustic tonometry. [PDF]

open access: yesPLoS ONE, 2023
In this study, we propose a comprehensive mechanical model of ocular bulb vibrations and discuss its implications for acoustic tonometry. The model describes the eye wall as a spherical, pre-stressed elastic shell containing a viscoelastic material and ...

Non-Invasive Ocular Rigidity Measurement: A Differential Tonometry Approach [PDF]

open access: yesActa Medica, 2015
Purpose: Taking into account the fact that Goldmann applanation tonometry (GAT) geometrically deforms the corneal apex and displaces volume from the anterior segment whereas Dynamic Contour Tonometry (DCT) does not, we aimed at developing an algorithm ...

Ocular Pulse Amplitude in Healthy Subjects as Measured by Dynamic Contour Tonometry [PDF]

open access: yesJAMA Ophthalmology, 2006
To test whether dynamic contour tonometry yields ocular pulse amplitude (OPA) measurements that are independent of corneal thickness and curvature, and to assess variables of observer agreement.In a multivariate cluster analysis on 223 eyes, the relationship between central corneal thickness, corneal curvature, axial length, anterior chamber depth ...

A Novel Ocular Tonometry Task Trainer. [PDF]

open access: yesCureus, 2022
The measurement of intraocular pressure via ocular tonometry is a skill necessary for the evaluation of emergency department patients with ocular complaints. Accurate results inform the use of time-sensitive medications or invasive procedures. We sought to develop and evaluate an affordable, realistic, and reproducible task trainer to allow Emergency ...

The influence of ocular parameters on intraocular pressure values measured by different devices and the development of an optimized prediction model in a myopic population [PDF]

open access: yesAdvances in Ophthalmology Practice and Research
Objective: To investigate the associations between ocular parameters—mean keratometry (Km), spherical equivalent (SE), central corneal thickness (CCT), axial length (AL), corneal hysteresis (CH), and corneal resistance factor (CRF)—and intraocular ...

Comparison of dynamic contour tonometry and noncontact tonometry in ocular hypertension and glaucoma [PDF]

open access: yesEye, 2008
To assess the agreement in the measurement of intraocular pressure obtained by dynamic contour tonometer (DCT) and noncontact tonometer (NCT) in patients with glaucoma and ocular hypertension, to investigate the effect of corneal thickness on pressure readings by both instruments, and to assess the reproducibility of dynamic contour tonometer.NCT and ...

Consistency of Ocular Palpation Tonometry with Goldman Applanation Tonometry and Its Reproducibility by Separate Examiners

open access: yesBeyoglu Eye Journal, 2018
INTRODUCTION[|]Elevated intraocular pressure (IOP) remains to be the best known modifiable risk factor for glaucoma. Ocular palpation tonometry (OPT) is an old, fast and simple method for IOP measurement.

Comparison of intraocular pressure measured by Goldman applanation tonometer, noncontact tonometer and trans-palpebral tonometer [PDF]

open access: yesBMC Ophthalmology
Background To evaluate reliability and agreement of non-contact tonometry (NCT) and trans-palpebral tonometry (TPT) compared with Goldmann-applanation tonometry (GAT).
