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.

Comparative evaluation of TonoPen AVIA, Goldmann applanation tonometry and non-contact tonometry

International Ophthalmology, 2011
To compare the tonometric recordings of the Tono-Pen AVIA (TPA) with intraocular pressure (IOP) recordings made with Goldmann applanation tonometry (GAT) and non-contact tonometry (NCT). This prospective, observational, comparative case series consisted of 180 eyes of 180 subjects (50 patients with glaucoma and 130 healthy controls).

Goldmann Applanation Tonometry in Patients with Regular Corneal Astigmatism

American Journal of Ophthalmology, 1983
By averaging vertical and horizontal applanation readings from the Goldmann tonometer, we developed a simple technique that accurately measures intraocular pressure in patients with regular corneal astigmatism. This procedure eliminates the need for keratometry and oblique alignment of the applanator.

Rebound tonometry with re-sterilised tips versus Goldmann applanation tonometry in children

Archivos de la Sociedad Española de Oftalmología (English Edition), 2020
The Goldmann applanation tonometer (TAG) is the gold standard for the measurement of intraocular pressure (IOP). In paediatric patients this measurement is challenging. The rebound tonometer (TRB) is an easy to use instrument. In the National Ophthalmology Unit (UNO) the tips of the TRB are re-sterilised (TRB RE).To evaluate the correlation between TRB

Goldmann Applanation Tonometry Using Sterile Disposable Silicone Tonometer Shields

Ophthalmology, 1996
Placement of a sterile single-use cover over the tonometer tip may be a convenient and safe alternative method to repeated chemical disinfection. This study was undertaken to evaluate the accuracy and performance of Goldmann applanation tonometry using a sterile disposable silicone tonometer shield over the biprism tip.The same investigator measured ...

Digit Preference in Goldmann Applanation Tonometry: The Hedgehog Effect

American Journal of Ophthalmology, 2005
Digit preference is a subconscious bias towards numbers that end in certain digits. We conducted a study to assess for digit preference in intraocular pressure measurement using the Goldmann applanation tonometer.Prospective study with masked and unmasked phases.The study was conducted in general ophthalmic clinics in a District General Hospital in ...

Differences between Goldmann Applanation Tonometry and Dynamic Contour Tonometry in pseudoexfoliation syndrome

Clinical & Experimental Ophthalmology, 2010
AbstractPurpose:  To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) in eyes with pseudoexfoliation syndrome (PEX).Methods:  Thirty‐eight patients (38 eyes) with PEX in both eyes (pseudoexfoliative group, PG) as well as 19 patients (19 eyes) without PEX in either eye (control group, CG), were ...

Intraocular pressure difference in Goldmann applanation tonometry versus Perkins hand-held applanation tonometry in overweight patients

Ophthalmology, 1998
To analyze the increase in intraocular pressure (IOP) caused by anatomic and physiologic factors in overweight patients when using Goldmann applanation tonometry.A prospective cohort study.Seventy average-weight individuals who had no difficulties with IOP measurements at the slit lamp and 12 obese patients with suspected glaucoma who could position ...

[Theoretical basis of goldmann applanation tonometry].

Klinische Monatsblatter fur Augenheilkunde, 2005
For more than 50 years Goldmann applanation tonometry has been the internationally accepted method for measuring intraocular pressure. In Goldmann applanation tonometry, however, some basic physical properties are oversimplified and the method has some flaws and restrictions.

Comparison of dynamic contour tonometry and Goldmann applanation tonometry following penetrating keratoplasty

Canadian Journal of Ophthalmology, 2010
To evaluate dynamic contour tonometry (DCT) versus Goldmann applanation tonometry (GAT) intraocular pressure (IOP) measurements in eyes that underwent penetrating keratoplasty PKP). Prospective, cross-sectional, observational study.Thirty-one eyes of 28 patients were examined after PKP.All eyes had undergone PKP with interrupted sutures.
