Review on Dynamic Contour Tonometry and Ocular Pulse Amplitude [PDF]

Ophthalmic Research, 2015
Intraocular pressure (IOP) measurement is the cornerstone of the management of glaucoma patients. The gold standard for assessing IOP is Goldmann applanation tonometry (GAT). Recently, the dynamic contour tonometer (DCT) has become available. While both devices provide reliable IOP measurements, the results are not interchangeable.

Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry

PLOS ONE, 2017
The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA).Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ...

Ocular Tonometry and Sporadic Creutzfeldt - Jakob disease (sCJD): A Confirmatory Case-Control Study [PDF]

British Journal of Medicine and Medical Research, 2014
To evaluate the hypothesis that sporadic Creutzfeldt-Jakob disease (sCJD) may be transmitted through ocular tonometry.The infectious agent of sCJD may be present in the cornea prior to clinical symptoms. Cornea infectiousness has been documented by cornea transplants in guinea pigs and humans.

Comparison of Rebound and Applanation Tonometry in Eyes With Focal Corneal Edema. [PDF]

Vet Ophthalmol
ABSTRACT Objective To determine the effect of corneal edema on intraocular pressure (IOP) readings and their accuracy and precision when obtained with handheld rebound and applanation tonometers. Animals and Procedures IOP readings from areas of focal corneal edema were compared to those from clear cornea in 10 eyes of 7 glaucomatous cats in vivo using
