Dynamic Contour Tonometry

Journal of Glaucoma, 2005
With tonometers currently in use intraocular pressure is indirectly determined by measuring a physical quantity related to a specified deformation of the cornea. We present a new principle of direct, continuous, and transcorneal intraocular pressure measurement, describe its theoretical foundation, and evaluate its application on the basis of an in ...

Dynamic contour tonometry: principle and use

Clinical & Experimental Ophthalmology, 2006
AbstractInterindividual variability of central corneal thickness has been found to be a source of error for conventional Goldmann applanation tonometry. The dynamic contour tonometer represents a potentially new technology for non‐invasive and direct intraocular pressure (IOP) measurement, and has been proposed to accurately measure the true IOP ...

Dynamic contour tonometry versus Goldmann applanation tonometry: a comparative study

Graefe's Archive for Clinical and Experimental Ophthalmology, 2005
Various sources of error, including central corneal thickness (CCT) and structural corneal rigidity, have been proposed for Goldmann applanation tonometry (GAT). The Pascal dynamic contour tonometer (DCT) is a novel device designed for intraocular pressure (IOP) measurements assumed to be largely independent of CCT and corneal curvature.

Dynamic Contour Tonometry for Intraocular Pressure Measurement

American Journal of Ophthalmology, 2005
To compare dynamic contour tonometry as a new method for intraocular pressure measurement with Goldmann applanation tonometry.Clinical observational study.The study included 176 eyes of 126 subjects (39 eyes with open-angle glaucoma, 137 normal eyes) and consisted of 528 dynamic contour measurements and 352 Goldmann tonometry measurements.

Dynamic Contour Tonometry: Handheld versus Slit-lamp–Mounted

Ophthalmology, 2009
To compare the newly developed handheld dynamic contour tonometer (hh-DCT) with the established slit-lamp-mounted DCT (sl-DCT) in terms of agreement for intraocular pressure (IOP) and ocular pulse amplitude (OPA) measurements, intraobserver variability, and tonography effect.Evaluation of diagnostic technology.Fifty eyes of 50 healthy volunteers were ...

Comparison of Dynamic Contour Tonometry and Goldmann Applanation Tonometry in Keratoconus

Cornea, 2011
We performed a comparative study using Goldmann applanation tonometry (GAT) and dynamic contour tonometry (DCT) to measure intraocular pressure (IOP) in eyes with keratoconus.IOP was measured in 114 eyes of 75 patients with keratoconus (51 men and 24 women; mean age, 36.1 ± 11.2 years) using GAT and DCT in randomized order.

Applanation Tonometry Versus Dynamic Contour Tonometry in Eyes Treated With Latanoprost

Journal of Glaucoma, 2010
To examine the differences between Goldmann Applanation Tonometry (GAT) and Dynamic Contour Tonometry (DCT) associated with latanoprost use.Twenty-four eyes (of 24 patients) treated with latanoprost monotherapy (latanoprost group, LG), 11 eyes (of 11 patients) not receiving prostaglandin analogs (nonlatanoprost group, NLG), and 20 eyes of 20 ...

A Clinical Comparison of Dynamic Contour Tonometry Versus Goldmann Applanation Tonometry

Ophthalmic Surgery, Lasers and Imaging Retina, 2010
Background and Objective: To compare the intraocular pressures (IOP) obtained with dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) and to determine the dependency of both devices on corneal structure.

Intraocular Pressure Measurement-Comparison of Dynamic Contour Tonometry and Goldmann Applanation Tonometry

Journal of Glaucoma, 2006
The dynamic contour tonometer (DCT, Pascal tonometer, Swiss Microtechnology AG, Port, Switzerland) was recently introduced as a new method of intraocular pressure measurement, supposedly independent of corneal properties. In this study we analyzed the agreement and correlation of dynamic contour tonometry and Goldmann applanation tonometry (GAT) and ...

Dynamic Contour Tonometry in Keratoconus and Postkeratoplasty Eyes

Cornea, 2008
To compare the performance of dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in measuring intraocular pressure in eyes with irregular corneas.GAT and DCT measures were taken in 30 keratoconus and 29 postkeratoplasty eyes of 35 patients after pachymetry and corneal topography.
