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

Dynamic Contour Tonometry, Tono-Pen XL<sup>®</sup>, and Goldmann Applanation Tonometry in Comparison to Intracameral Intraocular Pressure (IOP) Measurements in Patients with Corneal Pathologies

, 2014
Purpose: The accuracy of Goldmann applanation tonometry (GAT) has been shown to depend on several biomechanical properties of the cornea. Newer tonometry devices (e.g., the Dynamic Contour Tonometer PASCAL? [DCT] and the Tono-Pen?

Significance of dynamic contour tonometry in evaluation of progression of glaucoma in patients with a history of laser refractive surgery

British Journal of Ophthalmology, 2019
Aims In this study, we tested the hypothesis that intraocular pressure (IOP) parameters measured by dynamic contour tonometry (DCT) would be more relevant in progression of glaucoma when there is a history of laser refractive surgery (LRS) than the IOP ...

Analysis of ocular pulse amplitude values in different pregnancy stages as measured by dynamic contour tonometry

, 2018
Background: Orbital circulation is influenced by systemic hormonal status. Ocular pulse amplitude (OPA) is a surrogate measurement of choroidal blood flow. We investigated the OPA profile during different stages of pregnancy.

Hand-held dynamic contour tonometry [PDF]

Acta Ophthalmologica, 2009
We present a prototype of the hand-held dynamic contour tonometer (HH-DCT) and prospectively compare this HH-DCT with the well-established Perkins applanation tonometer (PAT) and the TonoPenXL (TPXL).In a prospective, single-centre, randomized study, intraocular pressure (IOP) readings were taken in random order using HH-DCT, PAT and TPXL tonometers ...

Comparison of dynamic contour tonometry with Goldmann applanation tonometry in glaucoma practice [PDF]

Acta Ophthalmologica, 2008
Abstract.Purpose:  To compare intraocular pressure (IOP) readings taken using dynamic contour tonometry (DCT) with IOP readings taken with Goldmann applanation tonometry (GAT) in eyes with glaucoma or ocular hypertension.Methods:  The present study included 100 eyes in 100 patients with glaucoma or ocular hypertension. After pachymetry DCT and GAT were

Comparison between dynamic contour tonometry and Goldmann applanation tonometry. [PDF]

Korean J Ophthalmol, 2009
To compare the intraocular pressures (IOPs) measured by dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT), and to investigate the association of IOPs on eyes of varying central corneal thickness (CCT).In this prospective study, 451 eyes of 233 subjects were enrolled. IOPs were measured by GAT and DCT. CCT was measured three times

Relationships between target intraocular pressure and central corneal thickness in stabilized and non-stabilized glaucoma patients

Journal of Ophthalmology, 2021
Background: Until now, no direct relationship has been established between the target pressure and particular corneal thickness for measurements with different types of tonometers.
