A recently published clinical study ”Clinical comparison of the TonoVet(®) rebound tonometer and the Tono-Pen Vet(®) applanation tonometer in dogs and cats with ocular disease: glaucoma or corneal pathology” by researchers Lena von Spiessen, Julia Karck, Karl Rohn, and Andrea Meyer-Lindenberg, compared the TonoVet® to the Tono-Pen Vet® applanation tonometer in dogs and cats suffering from glaucoma or corneal abnormalities.
Measuring IOP accurately in diseased eyes matters
Animals with glaucoma or corneal disorders present unique challenges when measuring IOP. Factors like altered corneal thickness or structure can compromise the accuracy of traditional applanation tonometry. That’s why veterinary professionals need a tool that offers consistency, flexibility, and precision — all while being gentle on the patient and fast to use.
The study measured IOP in 26 glaucomatous eyes and 29 eyes with corneal pathology. Both tonometers were used on each subject, and in cases with corneal changes, readings were taken from both healthy and affected areas of the eye. The goal: to understand how each device responds to real-world pathology.
The TonoVet® shows consistent, repeatable results
The TonoVet® not only consistently measured higher IOP values in glaucomatous eyes, but its results showed a strong correlation with those from the Tono-Pen Vet®; highlighting both its sensitivity and reliability. The findings suggest that TonoVet® is not only accurate, but more stable across a variety of ocular conditions — exactly what vets need when treating complex cases.
