PURPOSE To investigate agreement in intraocular pressure (IOP) measurements among Icare rebound tonometry, Tonopen tonometry, and Goldmann applanation tonometry following vitreoretinal surgery. DESIGN Reliability analysis of tonometers. METHODS Fifty-eyes of 50 adults undergoing vitreoretinal surgery were enrolled. IOP was measured on first postoperative day using Icare (Tiolat, Helsinki, F...

PURPOSE The aim of this study was to compare intraocular pressure (IOP) measurements obtained by Goldmann tonometry (GT), the Tonopen XL, and a new transpalpebral tonometer, TGDc-01, in eyes that had undergone penetrating keratoplasty (PKP). METHODS IOP was measured in post-PKP eyes by means of GT, Tonopen XL, and TGDc-01. Central corneal thickness measurements were also obtained for all eyes...

PURPOSE Post-Descemet stripping endothelial keratoplasty (DSEK) patients are prone for intraocular pressure (IOP) elevations and glaucoma. Corneal characteristics influence various IOP measuring devices in various ways. The aim of this study was to evaluate the agreement between four different IOP measuring devices: Goldmann applanation tonometer (GAT), I-care pro, Tonopen XL, and Schiotz tonom...

Background: Glaucoma is the world's leading cause of preventable irreversible blindness. The most important risk factor of glaucoma is increase in the intraocular pressure.Hence, timely screening by accurate IOP measurements is of utmost importance. In recent years, Tonopen has emerged as an alternative to Goldmann applanation tonometer which is the ‘gold standard’ for IOP measurement because o...

PURPOSE The purpose of this study was to evaluate the Tono-Pen 2 tonometer for measuring intraocular pressure (IOP) in the living rat eye. METHODS One eye from each of 20 adult, anesthetized brown Norway rats (group 1) was cannulated and simultaneously connected to a syringe and a pressure transducer with a chart recorder. We increased IOP from 15 to 45 mmHg in 5-mmHg increments and obtained ...

purpose : to investigate intraocular pressure (iop) changes due to different serum level heights by using tonopen in acquired globes from the iran eye bank (ieb). methods : in this interventional prospective case series, serum were infused into 18 normal globes acquired from ieb by using 21g needle inserted in vitreal space through optic nerve head to change the iop by different fluid level hei...

The definition of glaucoma is an elevated intraocular pressure. Normal intraocular pressures in dogs are 12-24mmHg. The pressure is best measured by tonometry and the most common tonometers are the Tonopen, TonoVet, and Schiotz tonometers. The Tonopen and TonoVet are more easily utilized but the Schiotz can also be accurate when the user is adequately trained in its use. Glaucoma can be either ...
