BackgroundDiaton transpalpebral tonometry is a new version of TGDc-01 transpalpebral tonometry. The aim of this study is to evaluate the reliability of this method, and to compare the results with those of corrected Goldmann applanation tonometry (c-GAT), which is the “gold standard” for the clinical measurement of IOP.MethodsIOP was measured in 212 eyes of 129 subjects by means of two different methods. Measurements with two tonometers were performed in random order, and the measurements of… 

Comparison of Diaton transpalpebral tonometer with applanation tonometry in keratoconus.

Measurements obtained using a Diaton tonometer are not affected by corneal biomechanics; however, its poor agreement with Goldmann AT values calls into question the added value of using a Tournais tonometer to measure intraocular pressure in keratoconus.

Comparative Evaluation of Diaton and Goldmann Applanation Tonometers

The Diaton measurements do not correlate well with those provided by applanation tonometry and the two tonometers show very wide limits of agreement so they may not be used interchangeably in clinical practice for the measurement of IOP.

Comparison of Intraocular Pressure Measurement with Schiotz Tonometer and Tono-Pen Vet Tonometer in Healthy Dogs

Correlation coefficients calculated for the results obtained in the right and left eyes using two tonometers indicated highly correlative relationships between the results, showing that both tonometers can be advantageously used in clinical practice to measure intraocular pressure in dogs.

Comparison of Goldmann Applanation , Diaton Transpalpebral and Air Puff Tonometers

Material and Methods: A total of 400 eyes of 200 random subjects were included in this cross-sectional, comparative study, and IOP was measured with APT, followed by Diaton®, and lastly GAT in both eyes.

Measuring intraocular pressure

Clinicians should recognize that a single IOP measurement is but an often error-prone snapshot of a widely varying physiologic parameter, and IOP data should only be used in the context of the overall clinical picture.

Indentation tonometry : Schiotz tonometer

This chapter aims to explore various tonometry devices available in the market while explaining their working principles, features, advantages, and disadvantages.

Comparison of Pneumatonometry and Transpalpebral Tonometry Measurements of Intraocular Pressure during Scleral Lens Wear

Assessment of IOP during sCleral lens wear varies based upon the instrument that is used, and clinicians should continue to monitor optic nerve structure and function in scleral lens wearers, as they do in all patients.

Intraocular pressure menagement with transpalpebral tonometry Transpalpebral tonometri ile göz içi basinci ölçülmesi

The transpalpebral tonometer is new method and measures IOP without corneal contact through the eyelid and is regarded as the “gold standard’’ of measuring IOP.



Transpalpebral measurement of intraocular pressure using the TGDc-01 tonometer versus standard Goldmann applanation tonometry

The TGDc-01 is not a reliable tool for IOP measurement in clinical routine because the IOP values obtained are generally lower and less accurate than those obtained with the Goldmann tonometer.

Deviations between transpalpebral tonometry using TGDc-01 and Goldmann applanation tonometry depending on the IOP level

TGDc-01–based tonometry demonstrated an increasing underestimation of IOP with increasing IOP levels when compared with the current standard method of Goldmann applanation tonometry.

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.

Measurement of the intraocular pressure with the “transpalpebral tonometer” TGDc-01 in comparison with applanation tonometry

The eyelid tonometer may be helpful as a screening tool when Goldmann applanation tonometry is not applicable, but in more than 10% of the measurements the IOP readings differed by more than 3 mmHg.

Central corneal thickness and Diaton transpalpebral tonometry

The Diaton measurements show moderate correlation with those provided by applanation tonometry, but seems to be more affected by the corneal thickness, especially in the thinnest corneas.


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

Effect of central corneal thickness, corneal curvature, and axial length on applanation tonometry.

Central corneal thickness significantly affects IOP reading obtained by applanation tonometry according to the Goldmann principle, and a correction of IOP readings by considering CCT according toThe Dresdner correction table might be helpful for determining an accurate IOP value.
