Goldmann Applanation Tonometry Free of the Slitlamp
Archives of Ophthalmology, 2010A 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 Tonometry without Fluorescein
Optometry and Vision Science, 1981Recently, 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 ...

Comparison of Proview phosphene tonometry with Goldmann applanation tonometry
Canadian Journal of Ophthalmology, 2006To 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 ...

Multiparameter Correction Equation for Goldmann Applanation Tonometry
Optometry and Vision Science, 2011To 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 ...

Clinical Evaluation of Applanation Resonance Tonometry
Journal of Glaucoma, 2007The purpose of this study was to calibrate and evaluate the precision of the new applanation resonance tonometry (ART) in a clinical study designed in accordance with the International Standard Organization's requirements.This was a prospective, randomized, single-center study, where healthy volunteers and patients participated.

Comparison of Dynamic Contour Tonometry and Goldmann Applanation Tonometry in Keratoconus
Cornea, 2011We 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.

Goldmann applanation versus hand-applanation and Schi�tz indentation tonometry
Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1975For 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, 2019While 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 ...

Clinical Comparison of the Icare Tonometer and Goldmann Applanation Tonometry
Journal of Glaucoma, 2008To compare a new method of intraocular pressure (IOP) measurement, using the Icare tonometer, with Goldmann applanation tonometry (GAT).Two observers obtained IOP readings in 292 eyes (143 right and 149 left) of 153 subjects, using the Icare without topical anesthetic. A GAT reading was subsequently obtained by a consultant ophthalmologist, without the
