If your pet needs to have an eye exam, contact us today!

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 instrumentation that allows us to measure intraocular pressure – the pressure inside the eye. In order to measure this pressure, we use a Tono-Pen a handheld device shaped like a large marker. It provides a digital readout of the amount of force being exerted on the eye.

Tonometry is used to diagnose glaucoma, a common and painful disease characterized by increased fluid pressure inside the eye. It often damages the ocular nerve causing decreased vision (tunnel vision) and even blindness. Early detection is key in preventing permanent vision changes.
