What eye pressure is normal for dogs?
Normal eye pressure is on average 15-20 mm Hg for the dog and cat. When eye pressure is elevated above normal and evidence of ocular damage in the eye is occurring, glaucoma is present.
How do they check eye pressure in dogs?
Tonometry is an easy way to check for increased intraocular pressure and can be used without sedation because pets tolerate it very well. A numbing drop is placed into each eye before the test, and a specialized instrument is lightly touched to the cornea of the eye to measure the pressures.
What is tonometry used to diagnose?
Tonometry is a test to measure the pressure inside your eyes. The test is used to screen for glaucoma and to measure how well glaucoma treatment is working. People over age 40 years, particularly African Americans, have the highest risk for developing glaucoma. Regular eye exams can help detect glaucoma early.
How can you tell if your dog has glaucoma?
What are the signs and symptoms of glaucoma?
- Watery discharge from the eye.
- Eye pain (eye rubbing or turning away when being pet)
- Bulging of the eyeball (whites of eye turn red)
- Cloudy, bluish appearance to eye.
- Dilated pupil – or pupil does not respond to light.

Can glaucoma in dogs be cured?
Important Facts About Glaucoma in Pets: There is no cure for glaucoma, only control of the disease with further treatment. Medication for glaucoma is lifelong. Permanent blindness may occur WITHIN HOURS if increased intraocular pressure is maintained.
What is dog tonometry?
Tonometry is the measuring of an animal’s eye pressure (intraocular pressure) to detect signs of glaucoma or other eye disorder. A handheld device called a tonometer is used by your veterinarian in Monrovia to evaluate IOP in dogs and cats.
Why is tonometry important?
Tonometry is a diagnostic test that measures the pressure inside your eye, which is called intraocular pressure (IOP). This measurement can help your doctor determine whether or not you may be at risk of glaucoma. Glaucoma is a serious eye disease that can eventually lead to vision loss if untreated.
What causes low eye pressure in dogs?
Common causes are: infections; including viral (rabies, distemper), bacterial (Lyme disease, leptospirosis), parasitic (toxoplasmosis, ehrlichiosis) or fungal (blastomycosis, histoplasmosis, cryptococcosis, coccidioidomycosis) metabolic disease (such as diabetes)
What does glaucoma look like in a dog?
Eye pain (eye rubbing or turning away when being pet) Bulging of the eyeball (whites of eye turn red) Cloudy, bluish appearance to eye. Dilated pupil – or pupil does not respond to light.
What is tonometry in dogs?
Tonometry is the measurement of pressure within the eye (called intraocular pressure) to determine if glaucoma is present in dogs. Intraocular pressure (IOP) is the pressure exerted against the outer layers by the eyeball. Tonometry is performed using an instrument called the tonometer. What Does Tonometry Reveal?
Can a dog be sedated prior to a tonometry?
A struggling patient can be sedated prior to tonometry but most sedatives will decrease IOP. The IOP of dogs are generally highest in the morning, and the IOP of cats are highest in the evening. The time at which tonometry was performed, and any prior sedation, should therefore be recorded with any IOP measurement.
How does the Tono-pen vet™ applanation tonometer work?
The Tono-Pen Vet™ applanation tonometer can flatten a miniscule section of the cornea within 40 milliseconds. During this time period a footplate is advanced from the probe that strikes and momentarily flattens the cornea. When the footplate is completely covered with membrane the surface of the cornea must be flat against it.
How do you use a tonometer correctly?
The instrument is first held tip down to maximally extend the footplate, and then tip up to maximally retract the footplate. The tonometer’s computer will then adjust its measurements accordingly in use. During use the tonometer is held approximately perpendicular to the cornea to further minimize gravitational effects.
