Effect of Central Corneal Thickness and Corneal Hysteresis on Tonometry as Measured by Dynamic Contour Tonometry, Ocular Response Analyzer, and Goldmann Tonometry in Glaucomatous Eyes

Journal of Glaucoma, 2008
The dynamic contour tonometer (DCT; Pascal tonometer) and the Ocular Response Analyzer (ORA) are novel tonometers designed to measure intraocular pressure (IOP) independent of corneal properties and central corneal thickness (CCT), respectively. We wanted to compare the corneal compensated IOP (IOPcc) as measured by ORA with IOP values measured by DCT ...

Measurement of Intraocular Pressure with Goldmann Applanation Tonometry, Dynamic-Contour Tonometry, and Ocular Response Analyzer

, 2016
Intraocular pressure (IOP) is an eye parameter of fundamental importance for the diagnosis of several eye conditions. The clinical standard for IOP measurement is Goldmann applanation tonometry (GAT), which has been the basis for the studies that determined current glaucoma management. Nevertheless, GAT is endowed with a number of limitations, so newer

Association of Ocular Hypotensive Medication Types with Dynamic Contour Tonometry and Goldmann Applanation Tonometry Measurements in a Glaucoma and Ocular Hypertensive Population

Journal of Ocular Pharmacology and Therapeutics, 2013
The aim of this study was to evaluate the association between different intraocular pressure (IOP)-lowering medications and IOP measurements by dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in a glaucoma and ocular hypertensive population.In a prospective, observational case series study, 410 eyes from 410 consecutive ...

Intraocular Pressure Values Obtained by Ocular Response Analyzer, Dynamic Contour Tonometry, and Goldmann Tonometry in Keratokonic Corneas

Journal of Glaucoma, 2010
To determine the agreement between dynamic contour tonometer (DCT), Goldmann applanation tonometer (GAT), and Ocular Response Analyzer (ORA) in keratoconic corneas and to find out the effect of corneal biomechanics on intraocular pressure (IOP) measurements obtained by these devices.IOP was measured with the ORA, DCT, and GAT in random order in 120 ...

Comparison of dynamic contour tonometry and Goldmann applanation tonometry and their relationship to corneal properties, refractive error, and ocular pulse amplitude

Optometry - Journal of the American Optometric Association, 2009
Accurate intraocular pressure (IOP) measurement is essential in diagnosing and managing glaucoma. Dynamic contour tonometry (DCT) is less dependent on corneal properties, such as thickness, elasticity, and rigidity, than Goldmann applanation tonometry (GAT).

Ocular Rigidity and Tonometry

2021
There are many ways to measure the intraocular pressure (IOP) and all are influenced to some degree by the individual characteristics of the eye. Ocular rigidity (OR) is a familiar concept used in ophthalmology to describe the relationship between pressure and volume changes in the eyeball. This concept partly explains why IOP measurements vary between

The Relationship Between Corvis ST Tonometry Parameters and Ocular Response Analyzer Corneal Hysteresis

Journal of glaucoma, 2020
Precis: Corvis ST Tonometry and Ocular Response Analyzer (ORA) measurements were conducted in primary open-angle glaucoma and normative subjects. Many parameters were significantly correlated, however, the strengths were weak to moderate.

System Identification Approach to Ocular Tactile Tonometry

Volume 5: Biomedical and Biotechnology, 2023
Abstract Frequent intraocular pressure (IOP) measurements are necessary for the diagnosis and management of glaucoma. Most current tonometers utilize some form of corneal deformation in order to estimate the IOP. Trans-corneal tonometers require sterile parts, or are complex and expensive (air-puff tonometer).
