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

Non-Invasive Ocular Rigidity Measurement: A Differential Tonometry Approach [PDF]
Acta 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 mechanical model of ocular bulb vibrations and implications for acoustic tonometry.
PLoS 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 ...

A Novel Ocular Tonometry Task Trainer
Cureus, 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 ...

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

Ocular tonometry in critically ill patients and their behaviour
Spanish Journal of Legal Medicine, 2021 Abstract Introduction The study of the post-mortem interval is an important element in the investigation of criminal acts. It is also one of the most difficult variables to quantify and establish. Various cadaveric phenomena are used to assess it, some of which are ocular, such as intraocular pressure.

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

A large multi-ethnic genome-wide association study identifies novel genetic loci for intraocular pressure. [PDF]
, 2017 Elevated intraocular pressure (IOP) is a major risk factor for glaucoma, a leading cause of blindness. IOP heritability has been estimated to up to 67%, and to date only 11 IOP loci have been reported, accounting for 1.5% of IOP variability.

Intraocular pressure in a cohort of healthy Eastern European schoolchildren: variations in method and corneal thickness [PDF]
, 2012 BACKGROUND: Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different
