Clinical Comparison of the Icare Tonometer and Goldmann Applanation Tonometry

Journal of Glaucoma, 2008
To 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

Comparison of the Icare rebound tonometry with the Goldmann applanation tonometry in a pediatric population

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2015
We report the results of a comparative study at a single center on 214 eyes of 109 pediatric patients in whom IOP was measured using the Icare rebound tonometer and Goldmann applanation tonometry. Measurements from the two modalities demonstrated a correlation coefficient of 0.83 (P < 0.001), with Icare measuring on average 1.38 mm Hg higher.

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 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.

[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).

[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 ...
