Tonometry is a diagnostic procedure used to determine intraocular pressure, with the help of a special instrument-tonometer. The tonometer is an electronic device equipped with a pressure sensor, which accurately assesses the intraocular pressure in many types of pets: dogs, cats, rabbits, birds, hamsters, house mice, ferrets and rats.
Elevated intraocular pressure can cause rapid damage to the back of the eye and lead to complete blindness within 12 hours of onset. Early detection of elevated intraocular pressure is an important step in preventing vision loss in pets. Tonometry is performed after the application of a local anesthetic in the form of drops, so that pets do not feel uncomfortable during this examination procedure.
