Airpuff tonometry versus applanation tonometry

Acta Ophthalmologica, 1990
Abstract In order to study the reliability of airpuff tonometry, 230 eyes of 115 patients had their IOP measured with 2 airpuff tonometers, NCT and Pulsair, and one applanation tonometer, Perkins handheld Goldmann Type, between Dec 87 and March 89. Each patient had three readings per eye with each airpuff instrument and two readings per eye with the ...

Clinical Evaluation of Applanation Resonance Tonometry

Journal of Glaucoma, 2007
The 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.

Accommodation and Applanation Tonometry

Archives of Ophthalmology, 1961
In a preceding publication, 1 the calculated C value of tonography was shown to be significantly affected by whether the eye, during tonography, was in the accommodated or relaxed state. The C values obtained during accommodation were significantly larger. Furthermore, attentive fixation of the "fixation-light" of the slit lamp for 4 min.

Schiotz and Applanation Tonometry

Archives of Ophthalmology, 1963
In preceding publications, 1,2 it was shown that, when a large population of normal eyes was examined by applanation and Schiotz tonometry, the agreement between the value of the arithmetic averages, obtained by the two systems of measurement, was not reflected in measurements obtained in the individual eye.

Applanation Tonometry of Breasts

Plastic and Reconstructive Surgery, 1979
We present a simple method for measuring intramammary pressure. We believe this technique could be helpful in evaluating the firmness of breasts following the implantation of prostheses, and capsulotomies done for this reason.

Axial length in applanation tonometry

Journal of Cataract and Refractive Surgery, 2002
To investigate the clinical applicability of a physical principle that suggests that a large globe offers less resistance to applanation than a smaller one.Referral practice, Bridgeport, Connecticut, USA.The correlation between axial length and applanation tonometry in 513 adult eyes, arbitrarily chosen from a referral practice, was examined using ...

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 ...

Applanation Tonometry with and Without Fluorescein

American Journal of Ophthalmology, 1980
Some investigators have suggested that it is not necessary to be fluorescein when doing applanation tonometry. This is incorrect because, in order to visualize the apex of the tear order to visualize the apex of the tear meniscus which defines the applanated area, the tears must be stained with fluorescein. I found an average pressure of 11.72 +/- 3.20

REPEATED APPLANATION TONOMETRY IN OPTIC ATROPHY

Acta Ophthalmologica, 1972
In eight cases with unilateral optic atrophy, the decrease of IOP on repeated applanation measurements was found to be less in the eyes with optic atrophy than in the normal fellow eyes. The consensual effect was reduced in the normal eye and normal in the damaged one.

Indentation and Applanation Tonometry in Rabbits

Archives of Ophthalmology, 1969
Two types of tonometers, indentation and applanation, were compared for their ability to accurately measure intraocular pressure (IOP) in rabbit eyes. Manometric measurements were made by vitreous cannulation to minimize the physiological and technical disadvantages associated with simultaneous aqueous chamber manometric measurement and tonometric ...
