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.

A comparison of Perkins and Goldmann applanation tonometry.

Journal of the American Optometric Association, 1987
In a study of 103 eyes, the measurement of intraocular pressure (IOP) was compared between the Perkins hand-held tonometer and the Goldmann slit lamp mounted tonometer. IOP readings from the two instruments were highly correlated (+0.91). Advantages inherent to the Perkins design are also discussed.

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 ...

[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.

[A comparison of rebound tonometry (ICare) with TonoPenXL and Goldmann applanation tonometry].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2007
Goldmann applanation tonometry and dynamic contour tonometry (PASCAL) are two well established slit lamp mounted tonometric methods. Intraocular pressure measurement in bedridden patients and children is often only possible using hand held tonometers (TonoPenXL, Perkins tonometer, Draeger tonometer).

Ocular Response Analyzer and Goldmann Applanation Tonometry

Journal of Glaucoma, 2010
Correlation of findings of the Reichert Ocular Response Analyzer (ORA) with Goldmann applanation tonometry (GAT).Observational, cross-sectional study.The study was conducted on 103 eyes of 56 patients, aged 41 to 78 years; average (±SD) 58.9 (±9.8) years attending the outpatient clinic of the Department of Ophthalmology, Alexandria University, for a ...

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).

[Sources of error in Goldmann applanation tonometry].

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2012
Reliable measurements of the intraocular pressure (IOP) are necessary for glaucoma patients. The measuring procedure, anatomical changes of the eye or extraocular influences can lead to errors during applanation tonometry. The IOP is overestimated if measured through the wrong eyepiece of the slit lamp, if a force is interfering with the tonometer arm ...
