Goldmann Applanation Tonometry without Fluorescein

Optometry and Vision Science, 1981
Recently, there have been several suggestions that Goldmann applanation tonometry can be performed without fluorescein. In order to determine the clinical efficacy of performing Goldmann applanation tonometry without fluorescein, 100 consecutive patients had applanation tonometry performed without fluorescein (Ophthetic only) and with fluorescein ...

Multiparameter Correction Equation for Goldmann Applanation Tonometry

Optometry and Vision Science, 2011
To develop a correction factor to improve the accuracy of intraocular pressure (IOP) measurements made by the Goldmann applanation tonometer (GAT), which considers the combined effects of variations in central corneal thickness (CCT), central anterior curvature (R), age, and the IOP level itself.Nonlinear numerical simulations based on the finite ...

Goldmann Applanation Tonometry Versus Dynamic Contour Tonometry After Vitrectomy

Journal of Glaucoma, 2016
Purpose: The aim of the study was to investigate the agreement of intraocular pressure (IOP) measurement using dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in eyes after vitrectomy with intraocular gas endotamponade, in eyes after vitrectomy with no tamponade, and in controls.

Comparison of Proview phosphene tonometry with Goldmann applanation tonometry

Canadian Journal of Ophthalmology, 2006
To compare intraocular pressures obtained using a handheld pressure phosphene tonometer (PPT) (Proview, Bausch & Lomb Pharmaceuticals, Inc., Tampa, Fla.) with Goldmann applanation tonometry.Comparative case series of 30 randomly selected patients.The readings obtained with the pressure phosphene tonometer display a higher mean and a larger standard ...

Goldmann Applanation Tonometry Free of the Slitlamp

Archives of Ophthalmology, 2010
A prototype device was developed for using the Goldmann applanation tonometer (GAT) without a slitlamp to make it potentially practical to measure intraocular pressure (IOP) away from the clinic. Inexpensive consumer video components and a small flashlight replaced the microscope and illuminator of the slitlamp in a device that was assembled to use a ...

Goldmann applanation versus hand-applanation and Schi�tz indentation tonometry

Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1975
For evaluation of hand-applanation tonometry comparative measurements of intraocular pressure have been carried out using the Goldmann applanation tonometer, the Draeger and Perkins hand-applanation tonometers and the Schiötz indentation tonometer. A series of 52 eyes has been tested.

Even-number Measurement Bias With Goldmann Applanation Tonometry

Journal of Glaucoma, 2019
While working with a large data set of Goldmann applanation tonometry (GAT) intraocular pressure (IOP) measurements for a separate investigation, we observed that the IOP distribution favored even-numbered values. Study of this phenomenon has been limited, and this larger data set enabled inquiry that showed new insight concerning the manner in which ...

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.

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.

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.
