Glaucoma in Dogs and Cats: Why Eye Pressure Testing Matters

Quick answer: Glaucoma is increased pressure inside the eye, and if it isn't treated promptly it can lead to permanent vision loss or blindness. At Middle Sackville Veterinary Care Centre, we check eye pressure with a tonometer. The test is quick, painless and doesn't require sedation, making it an easy way to protect your dog's or cat's eyesight, especially for breeds prone to glaucoma.

Eye problems can progress quickly, and pets often adapt to discomfort without making a fuss. Knowing the warning signs and keeping up with eye pressure checks can make a real difference. Here's what pet owners in Middle Sackville and the surrounding Sackville area should know about glaucoma and tonometry.

What is tonometry?

Tonometry measures the pressure inside your pet's eyes (intraocular pressure). We use a tonometer, a specialized device that measures eye pressure safely and accurately. Because the test is quick, painless and done without sedation, it's well suited to both dogs and cats.

Signs of eye trouble in dogs and cats

Contact us right away if you notice any of these signs:

• Dilated pupils
• Cloudiness in the cornea
• Red or bloodshot eyes
• One eye that looks a different size from the other
• Excessive squinting or tearing
• Pawing at the eyes or rubbing the face against furniture or the floor

Signs of discomfort like pawing and face rubbing may point to elevated eye pressure and should be checked promptly. For other subtle signals, see our article on recognizing pain in dogs and cats.

Which pets need regular eye pressure checks?

We recommend regular tonometry as part of ongoing care for:

• Breeds that are predisposed to glaucoma
• Pets with a history of eye injuries
• Any pet showing the warning signs above

Early detection and treatment are key to preventing irreversible damage, and early intervention makes a significant difference in managing eye pressure and keeping your pet's vision.

Other ways we care for your pet's eyes

• Eye surgery: our surgical services can address issues such as chronic infections and entropion, where the eyelashes damage the cornea. Surgery improves comfort, lowers the risk of corneal scarring and supports long-term vision.
• Specialist referrals: when a condition needs advanced care, we refer to board-certified veterinary specialists, including ophthalmologists, and stay in close contact with them so your pet's care stays coordinated. Learn more about our integrated support services.
