Checking IOP: Comparing iCare and GAT Results
2022年10月1日 · Initially, IOP was measured by ophthalmic technicians using iCare. Repeat measurements were performed within 90 minutes by a glaucoma specialist using GAT. Primary outcome measures included the correlation between iCare and GAT IOP readings and factors influencing the differences in those readings. IOP correlation.
Measuring true IOP: factors that confuse GAT readings
2008年6月2日 · The current gold standard for measuring intraocular pressure (IOP), the Goldmann tonometer (GAT), has considerable flaws. Dr Goldmann designed his tonometer to provide accurate measurements in eyes with average corneas, but we now know that many corneas vary significantly from the "average".
How to Measure Intraocular Pressure: An Updated Review of …
The gold standard technique in measuring IOP is still Goldmann applanation tonometry (GAT); however, this procedure requires local anesthetics, can be difficult in patients with scarce compliance, surgical patients and children, and is influenced by several corneal parameters.
What is the best way to measure intraocular pressure (IOP) in a …
Goldmann applanation tonometry (GAT) is the accepted industry standard for IOP measurement, with studies showing GAT to have excellent reproducibility, with intraobserver intraclass correlation coefficients (ICC) between 0.7 and 0.99, and …
Measuring IOP in the Unusual Cornea - American Academy of Ophthalmology
2015年5月20日 · For many ophthalmologists, Goldmann applanation tonometry (GAT) remains the gold standard, but it is susceptible to error due to variations in corneal biomechanics, Dr. Tanna said.
Comparison of intraocular pressure as measured by three different …
2017年11月2日 · To compare the measurement of intraocular pressure (IOP) among the three different non-contact tonometers (NCT) and the Goldmann applanation tonometer (GAT) for non-glaucomatous subjects. In 52 eyes of 52 non-glaucomatous subjects, IOP was measured sequentially with the Canon TX-20P, the Nidek NT-530P, the …
Comparisons of intraocular pressure measurements: Goldmann
2009年5月1日 · To compare intraocular pressure (IOP) readings between Tono-Pen tonometry and GAT, between noncontact tonometry (NCT) and GAT, and between dynamic contour tonometry (DCT) and Goldmann applanation...
Comparability of three intraocular pressure measurement: iCare …
2019年11月14日 · The purpose of this study was to compare the IOP values measured by NCT, iCare pro and GAT over a wide range of IOP. With GAT as the reference tonometer, the agreement and variability with CCT were compared between NCT and iCare, to evaluate the accuracy and reliability of the three IOP measurement methods.
GAT Simulation - GitHub Pages
Goldmann Applanation Tonometry (GAT) is the gold standard measurement apparatus for measuring intraocular pressure (IOP) and requires a high degree of skill to operate. Appropriate training to therefore essential. We developed a free online simulator, GatSim, which mimics the …
Comparison of intraocular pressure measured by ocular response …
2020年1月10日 · Although Goldmann Applanation Tonometer (GAT) is currently the internationally recognized gold standard for IOP measurement, its results are severely affected by central corneal thickness (CCT). Ocular Response Analyzer (ORA) takes certain biomechanical properties of cornea into account and is supposed to be less dependent of CCT.
