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

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 ...

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 ...

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.

Rebound, Applanation, and Dynamic Contour Tonometry in Pathologic Corneas

Cornea, 2013
To compare the practicability of using an Icare rebound tonometer (RT) versus a Goldmann applanation tonometer (GAT) or a Pascal dynamic contour tonometer (DCT) for measuring intraocular pressure (IOP) in patients with corneal abnormalities and, furthermore, to study the influence of central corneal thickness, corneal diameter, corneal radius, 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.

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

2006
Dynamic contour tonometry (DCT) is a new technology for noninvasive and direct measurement of intraocular pressure (IOP); its results are thought to be influenced less than those of other methods by structural characteristics of the eye. The curvature of the pressure sensing device is concave and only slightly flatter than that of the human cornea. The

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 ...

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.
