Repeatability, reproducibility and agreement of intraocular pressure measurement in rabbits by the TonoVet and Tono-Pen
Tono-Pen and TonoVet have been used in rabbits to measure intraocular pressure (IOP) and investigate the effect of IOP lowering therapies. Therefore, their reliability and accuracy are very important and deserve careful evaluation. Our results showed that the with-subject deviation (Sw) and intraclass correlation coefficient (ICC) of the TonoVet and Tono-Pen were 0.61 mmHg/0.83 mmHg and 0.97/0....
متن کاملNoninvasive measurement of rat intraocular pressure with the Tono-Pen.
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 ...
متن کاملIntraocular pressure measurement in cynomolgus monkeys. Tono-Pen versus manometry.
PURPOSE In living cynomolgus monkey eyes, the authors compared manometrically set and measured intraocular pressure (IOP) with simultaneous IOP readings obtained with the Tono-Pen (TP), a handheld applanation tonometer based on the Mackay-Marg principle. METHODS In three pentobarbital-anesthetized cynomolgus monkeys, IOP was set and measured manometrically after anterior chamber cannulation t...
متن کاملmeasurement of intraocular pressure using schiotz vs tono-pen tonometers in patients with primary congenital glaucoma
purpose: to compare the tono-pen and schiotz tonometers in measurement of intraocular pressure (iop) in patients with primary congenital glaucoma. methods: this study was conducted on 38 eyes of 20 patients with primary congenital glaucoma. all measurements were performed under general anesthesia. one minute after receiving halothane 3% iop was determined by tono-pen and then by schiotz tonomet...
متن کاملIntraocular pressure measurement after penetrating keratoplasty: minified Goldmann applanation tonometer, pneumatonometer, and Tono-Pen versus manometry.
The accuracy of intraocular pressure measurement with the minified Goldmann applanation tonometer, the pneumatonometer, and the Tono-Pen tonometer were compared in post-mortem human eyes which had undergone penetrating keratoplasty. Enucleated post-mortem human eyes underwent same sized (7.75 mm) or 0.5 mm oversized (8.25 mm) autologous penetrating keratoplasty. Intraocular pressure was then se...
