ZusammenfassungHintergrundDie indirekte Messung nach Goldmann gilt als zuverlässigste Methode der Augeninnendruckbestimmung in der klinischen Praxis, ist aber problematisch bei Hornhautirregularitäten und nach Hornhautchirurgie. In dieser Pilotstudie wurden die Messwerte eines transpalpebral messenden Tonometers an gesunden Augen und nach perforierender Keratoplastik mit der Standard-Goldmann-Tonometrie verglichen.MethodeDas TGDc-01 rnißt den intraokularen Druck (IOD) transpalpebral nach dem… 

Messung des Augeninnendrucks (Tonometrie) mit unterschiedlichen Verfahren

Tonometry is the measurement of intraocular pressure (IOP), and many new techniques and devices for determining IOP have been developed, such as noncontact tonometry, the Tono-Pen, the ICare tonometer, dynamic contour tonometers, TGDc-01 tonometry and the ocular response analyzer.

Evaluation des mobilen TGDc-01-Tonometers und Vergleich mit dem Applanationstonometer nach Goldmann

ZusammenfassungHintergrundZiel der Untersuchung war der Vergleich der Messwerte sowie der Patientenakzeptanz eines neuen, digitalen, mobilen Tonometers (TGDc-01) mit der Applanationstonometrie nach

Glaukomanfall nach Hughes-Plastik

A case of acute glaucoma arising in a closed eye 10 days after lower eyelid reconstruction by Hughes tarsoconjunctival flap technique is presented and clinical strategies to avoid this complication are discussed.

Comparison of the Transpalpebral Tonometer TGDc-01 with Goldmann Applanation Tonometry

TGDC-01 may estimate intraocular pressure with a fair agreement to the Goldmann tonometer, although caution should be used for patients who require precise IOP measurements, which may be suitable for IOP screening.

Comparison of Noncontact tonometer with Goldmann Applanation tonometer for intraocular pressure measurement in non–glaucomatous patients in central India

This study compared the NCT with GAT for IOP measurements in non-glaucomatous patients in central India and found that mean difference of IOP was statistically significant in NCT and GAT, so NCT should not be used as diagnostic tool for Iop measurement.

Transpalpebral tonometry: reliability and comparison with Goldmann applanation tonometry and palpation in healthy volunteers

TGDc-01 could not be established as a substitute or diagnostic alternative method for Goldmann applanation tonometry, but as deviations between TGDc01 and goldmann turned out smaller than between palpation of IOP and Goldmann, TGDC-01 seems to provide a better choice for tonometry in patients.

Three portable tonometers, the TGDc‐01, the ICARE and the Tonopen XL, compared with each other and with Goldmann applanation tonometry *

Three portable tonometers, the TGDc‐01, the ICARE and the Tonopen XL, were compared with each other and to Goldmann applanation tonometry in a large group of healthy subjects and patients with ocular

Non contact tonometer & applanation tonometer as a screening tool for glaucoma in general population

The current study shows that the non contact tonometer compares favorably with the Goldmann applanation tonometer showing excellent agreement with it, and can be used as a reliable screening tool in general population.

A comparison of the Canon TX-20P™ non-contact tonometer and pachymeter in healthy eyes

A strong correlation was found between intraocular pressure and central corneal thickness measurements obtained with the Canon TX-20P™ with IOP measured with Goldmann applanation tonometer and CCT measured with ultrasound (US) pachymetry in healthy eyes.



Impressions- und Applanationstonometrie bei pathologischen Hornhäuten im Vergleich mit der intraokularen Nadeldruckmessung

Evaluating whether impression tonometry (Schioetz) is more precise than applanation tonometry in determinating the intraocular pressure in eyes with corneal disorders found it generally delivers falsely low measurements in comparison to intraocular needle tonometry.

Augeninnendruck und Tonometrie

Bei der Diskussion des Glaukombegriffes konnte der Augeninnendruck als „normal“ bezeichnet werden, der nicht zu einem Glaukomschaden des Sehnerven fuhrt. Leider kann eine derartige Definition nicht

[Impression and applanation tonometry in irregular corneas. Comparison with intraocular needle tonometry].

In corneal pathology both, applanation tonometry and impression tonometry do not deliver reliable results on an average and only intraocular needle-tonometry delivers reliable results in these eyes.

IOP measurement and central corneal thickness

In the recent paper by Feltgen and colleagues, the intraocular pressure was measured by Goldmann applanation tonometry and by using a cannula inserted into the anterior chamber connected with a pressure transducer omitting a possible influence of the cornea.


It is concluded that the central corneal thickness is a parameter which should be taken into consideration when evaluating applanation tonometer readings.

Measurement in Medicine: The Analysis of Method Comparison Studies

This paper shall describe what is usually done, show why this is inappropriate, suggest a better approach, and ask why such studies are done so badly.

Influence of Corneal Variables on Accuracy of Intraocular Pressure Measurement

Various methods of IOP measurement are reviewed, the basic principles involved and the advantages and disadvantages of each technique are summarized, and factors, factors, and focus are discussed.

A concordance correlation coefficient to evaluate reproducibility.

A new reproducibility index is developed and studied that is simple to use and possesses desirable properties and the statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation.
