Central Corneal Thickness, Tonometry, and Ocular Dimensions in Glaucoma and Ocular Hypertension

Journal of Glaucoma, 2001
To assess possible correlations between central corneal thickness, tonometry, and ocular dimensions.One hundred seventeen eyes of 117 patients who were not taking any intraocular pressure-lowering medications were studied prospectively. Forty-one patients had ocular hypertension; 13 patients had primary open-angle glaucoma; and 10 patients had normal ...

Association of Ocular Hypotensive Medication Types with Dynamic Contour Tonometry and Goldmann Applanation Tonometry Measurements in a Glaucoma and Ocular Hypertensive Population

Journal of Ocular Pharmacology and Therapeutics, 2013
The aim of this study was to evaluate the association between different intraocular pressure (IOP)-lowering medications and IOP measurements by dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) in a glaucoma and ocular hypertensive population.In a prospective, observational case series study, 410 eyes from 410 consecutive ...

Experimental and Numerical Analysis of Ocular Tactile Tonometry

Volume 2: Biomedical and Biotechnology, 2012
This article describes the experimental and numerical analysis of a novel trans-scleral tonometer based on the use of an instrumented form of digital palpation tonometry. Similar to manual digital palpation tonometery (estimation of the eye pressure via tactile touch), the novel ocular tactile tonometer utilizes multiple force probes to gather force ...

The Clinical Utility of Dynamic Contour Tonometry and Ocular Pulse Amplitude

Journal of Glaucoma, 2007
To determine if ocular pulse amplitude (OPA) as measured by dynamic contour tonometry (DCT) is related to severity of glaucoma, and if intraocular pressure (IOP) as measured by DCT is related to central corneal thickness (CCT).Patients were selected from the Duke Eye Center glaucoma clinic.

Comparing dynamic contour tonometry to Goldmann and hand-held tonometry in normal, ocular hypertension, and glaucoma populations

Annals of Ophthalmology, 2007
We prospectively compared dynamic contour tonometry (DCT) to Goldmann (GAT) and hand-held tonometry (HHT) in normal, ocular hypertension, and glaucoma populations. Both measurements were made on each patient within a 5-minute period during routine office exams over 4 months.

[Examinations by ocular pressure tonometry].

Klinische Monatsblatter fur Augenheilkunde, 1991
A new method has recently been suggested for the determination of the outflow resistance in the anterior chamber angle. In this method the intraocular pressure is set to 45 mmHg for 8 minutes. The intraocular pressure is measured after the removal of the suction cup. Values below 7 mmHg are obtained in healthy subjects.

Effect of Central Corneal Thickness and Corneal Hysteresis on Tonometry as Measured by Dynamic Contour Tonometry, Ocular Response Analyzer, and Goldmann Tonometry in Glaucomatous Eyes

Journal of Glaucoma, 2008
The dynamic contour tonometer (DCT; Pascal tonometer) and the Ocular Response Analyzer (ORA) are novel tonometers designed to measure intraocular pressure (IOP) independent of corneal properties and central corneal thickness (CCT), respectively. We wanted to compare the corneal compensated IOP (IOPcc) as measured by ORA with IOP values measured by DCT ...

[Relevance of ocular pressure tonometry and classical tonometry with reference to prognosis in suspected glaucoma and ocular hypertension].

Fortschritte der Ophthalmologie : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1992
A total of 44 eyes of patients with suspected glaucoma or ocular hypertension were examined both by ocular pressure tonometry (OPT) according to Ulrich and by tonography according to Leydhecker. The visual fields of these eyes were prospectively followed up for 3 years to compare the prognostic value of the two methods. In 30 of the 44 eyes a worsening

Intraocular Pressure Values Obtained by Ocular Response Analyzer, Dynamic Contour Tonometry, and Goldmann Tonometry in Keratokonic Corneas

Journal of Glaucoma, 2010
To determine the agreement between dynamic contour tonometer (DCT), Goldmann applanation tonometer (GAT), and Ocular Response Analyzer (ORA) in keratoconic corneas and to find out the effect of corneal biomechanics on intraocular pressure (IOP) measurements obtained by these devices.IOP was measured with the ORA, DCT, and GAT in random order in 120 ...
