Read this before you buy a tonometer


Eyeing a new veterinary tonometer? Here's a quick buying guide before you spend.

The tonometer is a critical instrument in basic eye exams, and it's very important for any exam of the eye. Veterinary ophthalmologist Robert Munger, DVM, DACVO, offers this advice to help you make the best buying decision:

"As with any examination, the practitioner must understand and interpret the findings in light of each clinical case. Examples include understanding how restraint, excitement, squinting, and thickening of the cornea (among other things) can affect the values they obtain and the practitioner must interpret the values with respect to their evaluation of the patient," says Dr. Munger. "In other words, the clinician needs to think! Medicine is not all rules and formulae. You have to interpret the values and apply what you know."
