TonoVet versus Tonopen in a high intraocular pressure monkey model.

Conclusions: In animals with normal IOP, the TonoVet and Tonopen tonometers produced consistent measurements. However, in a monkey model of chronic high IOP, the measurements obtained by these tonometers were inconsistent, with higher IOPs associated with larger measurement errors. Therefore, it is necessary to be aware that among different tonometers, there may be systemic errors and deviations in IOP measurements. These findings should facilitate efforts to obtain more accurate individualized diagnoses and prevent the utilization of misleading IOP values. PMID: 31523117 [PubMed - in process]
