What a great question to be asking — understanding conditions like glaucoma can really help you know what to watch for in Lucy.
What is glaucoma?
Glaucoma is a condition where pressure builds up inside the eye. The eye constantly produces and drains a fluid called aqueous humor. When that drainage doesn't work properly, pressure rises and can damage the optic nerve — the connection between the eye and the brain. Over time, that damage can affect vision.
Is it common in dogs?
Glaucoma does occur in dogs, and it's one of the more frequently seen eye conditions in veterinary practice. Some breeds are more prone to it than others — Cocker Spaniels, Basset Hounds, Chow Chows, Siberian Huskies, and several others have a higher genetic risk. Without knowing Lucy's breed, it's hard to say whether she falls into a higher-risk group, but glaucoma can develop in any dog.
Can it affect just one eye?
Absolutely — glaucoma can affect one eye, both eyes, or start in one eye and later involve the other. It's actually quite common for it to appear in one eye first. So yes, it could certainly affect her left eye specifically.
Signs to watch for in Lucy:
- Redness in the white part of the eye
- Cloudiness or a bluish haze over the eye
- The eye appearing larger or more "bulgy" than usual
- Squinting, blinking a lot, or pawing at the eye
- Sensitivity to light
- Seeming less interested in her surroundings or bumping into things
Two types to know about:
- Primary glaucoma — tends to be inherited and breed-related
- Secondary glaucoma — develops as a result of another eye problem, like inflammation or injury
Both types are serious, and early detection makes a real difference in protecting a dog's vision.
When to see your vet:
Glaucoma can progress quickly — sometimes within hours — so timing really matters. Please contact your vet as soon as possible (ideally within 24 hours) if you notice any of the signs listed above, especially redness, cloudiness, or a visibly enlarged eye. If Lucy is squinting or seems to be in pain, treat it as urgent and call your vet today. Even if you're just noticing something "off" about her eye and aren't sure what it is, that's reason enough to get her checked out. Eye issues are one area where it's always better to act quickly rather than wait and see.
