Comparison Between Dynamic Contour Tonometry and Goldmann Applanation Tonometry
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...
متن کاملGoldmann applanation tonometry in the conscious rat.
PURPOSE To determine whether the Goldmann applanation tonometer can be modified to measure intraocular pressure (IOP) in the conscious rat. METHODS In anesthetized rats Goldmann tonometers were tested that had reduced biprism angles in the applanating tips and reduced weights in the tonometer body from those used in humans and species with similar size eyes. Tonometers with tips with biprism ...
متن کاملGoldmann applanation tonometry versus i-care rebound tonometry
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...
متن کاملClinical comparison of the Icare tonometer and Goldmann applanation tonometry.
PURPOSE To compare a new method of intraocular pressure (IOP) measurement, using the Icare tonometer, with Goldmann applanation tonometry (GAT). PATIENTS AND METHODS Two observers obtained IOP readings in 292 eyes (143 right and 149 left) of 153 subjects, using the Icare without topical anesthetic. A GAT reading was subsequently obtained by a consultant ophthalmologist, without the knowledge ...
متن کاملApplanation pressure function in Goldmann tonometry and its correction.
So far applanation tonometry has not worked out any theoretical basis for correcting the result of intraocular pressure measurement carried out on a cornea with noncalibration dimensions by means of the Goldmann tonometer. All the tables of instrument reading corrections for cornea thickness or cornea curvature radius are based exclusively on measurements. This paper represents an attempt at cr...
