AIMS To establish the effects of central corneal thickness (CCT) on intraocular pressure (IOP) measured with a prototype Pascal dynamic contour tonometer (DCT), to evaluate the effect of CCT and age on the agreement between IOP measured with the Pascal DCT and Goldmann applanation tonometer (GAT), and to compare the interobserver and intraobserver variation of the DCT with the GAT. METHODS GA...

Background. To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) following trabeculectomy. Methods. Thirty eight glaucomatous eyes with a history of trabeculectomy (Trabeculectomy group, TG), 20 eyes without a history of trabeculectomy but with a history of latanoprost use (Latanoprost group, LG), and 19 nonglaucomatous eyes (Control group, C...

Glaucoma is usually considered to be adequately controlled when Goldmann applanation readings are below 22 mmHg. It is, however, now known that the intraocular pressure increases to a varying degree when the patient changes his posture from sitting to a recumbent position (Galin, McIvor, and Magruder, I963; Roberts and Rogers, I964; Hetland-Eriksen, Ig66a; Inglima, I966; Tarkkanen and Leikola, ...

Ophthalmologists rely on a device known as the Goldmann applanation tonometer to make intraocular pressure (IOP) measurements. It measures the force required to press a flat disc against the cornea to produce a flattened circular region of known area. The IOP is deduced from this force using the Imbert-Fick principle. However, there is scant analytical justification for this analysis. We presen...

The purpose of the study was to investigate the correlation between Corneal Visualization Scheimpflug Technology (Corvis ST tonometry: CST) parameters and various other ocular parameters, including intraocular pressure (IOP) with Goldmann applanation tonometry. IOP with Goldmann applanation tonometry (IOP-G), central corneal thickness (CCT), axial length (AL), corneal curvature, and CST paramet...

OBJECTIVE To evaluate the effect of central corneal thickness (CCT), corneal curvature, and axial length on applanation tonometry in an in vivo study. METHODS In a masked, prospective clinical trial, we examined 125 eyes of 125 patients scheduled for cataract surgery. Corneal curvature was measured by means of keratometry and axial length by A-scan ultrasonography. By cannulating the anterior...

Title Evaluation of a new rebound tonometer for self-measurement of intraocular pressure Subtitle Self-measurement using Icare Home showed good agreement with Goldmann applanation tonometry. Icare Home self-measurement was well accepted and reliable results obtained by 3 in 4 subjects, suggesting potential use for home measurement of intraocular pressure. Number of references = 26 Number of sup...
