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

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 ...

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 ...

A mechanical model of ocular bulb vibrations and implications for acoustic tonometry.

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 ...

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

open access: yesVet 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

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 ...

Topical Omidenepag Isopropyl Lowers Intraocular Pressure in Normal and Glaucomatous Cats: A Pilot Study. [PDF]

open access: yesVet Ophthalmol
ABSTRACT Purpose To evaluate the effects of topical prostaglandin E2 receptor 2 (EP2) agonist, omidenepag isopropyl (OMDI), on intraocular pressure (IOP) and pupil diameter (PD) in normal cats and cats with feline congenital glaucoma (FCG). Animals Studied Ten FCG cats and 8 normal cats.

Review on Dynamic Contour Tonometry and Ocular Pulse Amplitude [PDF]

open access: yesOphthalmic Research, 2015
Intraocular pressure (IOP) measurement is the cornerstone of the management of glaucoma patients. The gold standard for assessing IOP is Goldmann applanation tonometry (GAT). Recently, the dynamic contour tonometer (DCT) has become available. While both devices provide reliable IOP measurements, the results are not interchangeable.
