Journal of Glaucoma, 2008
The dynamic contour tonometer (DCT; Pascal tonometer) and the Ocular Response Analyzer (ORA) are novel tonometers designed to measure intraocular pressure (IOP) independent of corneal properties and central corneal thickness (CCT), respectively. We wanted to compare the corneal compensated IOP (IOPcc) as measured by ORA with IOP values measured by DCT ...

To determine the agreement between dynamic contour tonometer (DCT), Goldmann applanation tonometer (GAT), and Ocular Response Analyzer (ORA) in keratoconic corneas and to find out the effect of corneal biomechanics on intraocular pressure (IOP) measurements obtained by these devices.IOP was measured with the ORA, DCT, and GAT in random order in 120 ...

Optometry - Journal of the American Optometric Association, 2009
Accurate intraocular pressure (IOP) measurement is essential in diagnosing and managing glaucoma. Dynamic contour tonometry (DCT) is less dependent on corneal properties, such as thickness, elasticity, and rigidity, than Goldmann applanation tonometry (GAT).

Development of a Non-Invasive Calibration Method for Ocular Tactile Tonometry
Volume 3A: Biomedical and Biotechnology Engineering, 2013This article describes a novel method of indirect estimation of intra-ocular pressure using tactile sensors. Two sensor calibration methods have been demonstrated: an artificial neural network (ANN) model and a phenomenological reduced-parameter model based on finite element analysis. The ANN method showed superior performance with an accuracy of +/− 0.

Ocular Tonometry Through Sonic Excitation and Laser Doppler Velocimetry
Journal of Biomechanical Engineering, 1979Glaucoma is an insidious eye disease which must be detected in its early stages for there to be successful treatment. Primary detection of glaucoma and evaluation of therapy have depended upon tonometric methods which require applanation of the cornea. A new method of IOP determination which is noncontacting and nonapplanating has been devised.

Evaluation and Testing of Novel Ocular Tactile Tonometry Device
2014This article describes the experimental analysis of a novel trans-scleral tonometer based on the use of multiple force sensors forming a mechanical stiffness sensor. This approach is similar to an instrumented form of digital palpation tonometry in which manual palpation is used to conclude the stiffness, and hence, the intraocular pressure of the eye.

Ocular tonometry in the child under general anesthesia with IM ketamine.
Acta anaesthesiologica Belgica, 1977In the young child, the ocular tension cannot be taken without general anesthesia. Most of the anesthetic drugs lower the ocular tension which may give false low results in glaucoma. Ketamine is the only practical drug elevating the ocular tension. To determine the amount of the change in ocular tension under ketamine, the ocular tension was measured ...
