A Novel Ocular Tonometry Task Trainer
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]
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
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.

A mechanical model of ocular bulb vibrations and implications for acoustic tonometry
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 accounts for the interaction between the elastic corneoscleral shell and the viscoelastic vitreous ...

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

Intraocular pressure and ocular pulse amplitude using dynamic contour tonometry and contact lens tonometry [PDF]
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 study to compare the IOP results of this new device with Goldmann tonometry. Furthermore, IOP and OPA measured

Non-Invasive Ocular Rigidity Measurement: A Differential Tonometry Approach [PDF]
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 for the calculation of ocular rigidity (OR) based on the differences in pressure and volume between ...

To investigate the feasibility and to compare three devices measuring intraocular pressure (IOP) in mucopolysaccharidosis patients (MPS): iCare rebound tonometer (RT), Perkins applanation tonometer (PAT) and ocular response analyzer (ORA).MPS patients who underwent at least two examinations out of: RT, PAT and ORA at the same visit were identified and ...

The usefulness of CorvisST Tonometry and the Ocular Response Analyzer to assess the progression of glaucoma [PDF]
AbstractCorneal Visualization Scheimpflug Technology (CST) and Ocular Response Analyzer (ORA) measurements were carried out in 105 eyes of 69 patients with primary open-angle glaucoma. All patients had axial length (AL), central corneal thickness (CCT), intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) and eight visual fields (VF)s ...

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. Our aim is to investigate accuracy, reproducibility of ocular palpation tonometry and its suitability to be used for screening purposes.[¤]METHODS ...
