Your veterinarian may recommend tonometry if your pet:
- is a senior
- has a breed predisposition to glaucoma
- has diabetes
- has hypothyroidism
- has other chronic eye conditions or injuries
- has severe eye pain
Tonometry is a device that measures intraocular pressure, or the pressure inside the eye. We use a Tono-Pen, a handheld device shaped like a large marker, to measure this pressure. It gives a digital readout of the amount of force applied to the eye.
Glaucoma, a common and painful disease characterized by increased fluid pressure inside the eye, is diagnosed using tonometry. It frequently causes ocular nerve damage, resulting in decreased vision (tunnel vision) and even blindness. Early detection is critical for avoiding permanent vision changes.
