Comparison of three rebound tonometers in normal and glaucomatous dogs

Kimberly J. Hodgson et al.

Summary: This study compares intraocular pressure (IOP) readings obtained via three rebound tonometers in dogs with different stages of open-angle glaucoma (OAG) and normal control dogs. The results show that there are differences in IOP readings among the tonometers, and central corneal thickness (CCT) influences the measurements of all three tonometers.

Calibration of a novel rebound tonometer (Tono-Vera® vet) in the porcine eye

Erinn P. P. Mills et al.

Summary: The purpose of this study was to calibrate the Reichert Tono-Vera (R) Vet tonometer for use in porcine eyes and determine the most appropriate settings for pigs. The results showed that the dog setting on the Tono-Vera (R) Vet was the most accurate and precise compared to true intraocular pressures. Therefore, this setting is likely suitable for in vivo use in pigs with the appropriate correction formula applied.

Intraocular pressure measurements using the TONOVET(R) rebound tonometer: Influence of the probe-cornea distance

Blanche D. Rodrigues et al.

Summary: The study demonstrated that different probe-cornea distances significantly affect intraocular pressure (IOP) readings in dogs and rats, even within the 4-8 mm range recommended by the manufacturer. There was a small positive correlation between IOP values and probe-cornea distance in both species.
