PURPOSE To compare the intraocular pressures (IOPs) measured by dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT), and to investigate the association of IOPs on eyes of varying central corneal thickness (CCT). METHODS In this prospective study, 451 eyes of 233 subjects were enrolled. IOPs were measured by GAT and DCT. CCT was measured three times and the average was cal...

BACKGROUND The purpose of this study was to determine the accuracy of intraocular pressure (IOP) measurement after laser in situ keratomileusis (LASIK) or epithelial laser in situ keratomileusis (Epi)-LASIK using Goldmann applanation tonometry, air puff tonometry, ocular response analyzer corneal compensated IOP (ORA IOPcc) and Pentacam corrected IOP. METHODS A prospective comparative clinica...

Rabbits have played an important role in ophthalmological research processes, however the environment there has been a deficiency of sensitive equipment measurement intraocular pressure for this species. To compare (IOP) measured with rebound (TONOVET Plus®) and applanation (TONO-PEN VET®) tonometry healthy New Zealand rabbits treated Amlodipine. Twelve male white rabbits, 5 months old; two gro...

Accurate measurement of intra-ocular pressure is a fundamental component of the ocular examination. The most common method of measuring IOP is by Goldmann applanation tonometry, the accuracy of which is influenced by the thickness and biomechanical properties of the cornea. Algorithms devised to correct for corneal thickness to estimate IOP oversimplify the effects of corneal biomechanics. The ...

PURPOSE The dynamic contour tonometer is a nonapplanation contact tonometer designed to be largely independent of the structural properties of the cornea. Theoretically, it may measure intraocular pressure most accurately in abnormally thinner corneas. This study compares intraocular pressure measurements by dynamic contour tonometry with Goldman applanation tonometry in eyes with normal cornea...

T measurement of central corneal thickness (CCT) by pachymetry plays an integral part of the contemporary glaucoma workup. It is one of the relatively simple and straightforward ancillary tests performed today in the clinic. Clinicians have embraced this measure since the emergence of understanding its impact on the accuracy of tonometry such as Goldmann applanation tonometry (GAT). GAT, which ...

T he main purpose of my study was to compare the i-care tonometer to the Goldmann in terms of accuracy. Obviously when it comes to measuring IOP, accuracy is the most important aspect of any method of tonometry. However, there are other things to consider... patient comfort, repeatability (both inter and intra-practitioner) and who can actually use the device. So not only did I record the IOP r...

This study aims to determine the agreement of patient-measured intraocular pressure (IOP) using rebound tonometry with ophthalmologist-measured IOP using Goldmann applanation tonometry (GAT). Fifty-three glaucoma patients used rebound tonometry (Icare ONE, Icare Finland Oy., Finland) to measure their own IOP in ambient environments for 1 week, 5 times per day. Clinic IOP measurements were perfo...
