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 ...

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.

COMPARISON OF NONCONTACT TONOMETRY, GOLDMANN APPLANATION TONOMETRY WITH AND WITHOUT FLUORESCEIN

INDIAN JOURNAL OF APPLIED RESEARCH, 2022
Aims: This study aimed to compare the Intraocular Pressure (IOP) measurements with noncontact tonometer and Goldmann Applanation Tonometer with and without uorescein. Settings And Design: This cross-sectional study included 61 eyes attending the Ophthalmology Outpatient Department of a tertiary care hospital in South India.

APPLAMATIC TONOMETRY-GOLDMANN TONOMETRY-A PAIRED-READING COMPARISON STUDY

Optometry and Vision Science, 1974
ABSTRACT A paired‐reading study was performed to determine the effectiveness of the Applamatic tonometer as a clinical instrument by comparing its findings to Goldmann tonometric readings. The results reported that the instrument is a poor indicator of the Goldmann findings. There was no difference in whether a scleral or corneal site

Accuracy of Goldmann tonometry after refractive surgery

Journal of Cataract and Refractive Surgery, 1997
To assess the accuracy of Goldmann tonometry after refractive surgery.Refractive surgery center, Sherbrooke, Quebec, Canada.The charts of 824 patients who had radial keratotomy (RK) and 415 who had photorefractive keratectomy (PRK) by the same surgeon were retrospectively reviewed.

Multiparameter Correction Equation for Goldmann Applanation Tonometry

Optometry and Vision Science, 2011
ABSTRACT Purpose. 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 ...

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 versus Goldmann applanation tonometry: challenging the gold standard [PDF]

Expert Review of Ophthalmology, 2010
The accurate measurement of intraocular pressure (IOP) is fundamental to almost any ophthalmic examination. Dynamic contour tonometry (DCT) was introduced 5 years ago as an entirely novel contact tonometry principle designed to measure IOP largely ...

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.
