Glaucoma in dogs is a painful emergency — medications cost $50-$200/month and surgery runs $1,500-$3,000 per eye. Increased pressure inside the eye damages the optic nerve and retina, leading to permanent blindness within hours to days if untreated. Breed predisposition is strong, and most dogs eventually lose vision in the affected eye despite treatment.
Glaucoma occurs when fluid inside the eye (aqueous humor) can't drain properly, causing pressure to build. Primary glaucoma is inherited — the drainage angle is malformed from birth. Secondary glaucoma results from other eye diseases like lens luxation, uveitis, or tumors. The increased pressure damages the optic nerve and retina, causing pain and progressive vision loss. Primary glaucoma is inherited and bilateral
A red, painful eye — the dog may squint or avoid bright light. A dilated pupil that doesn't respond to light. Cloudiness or bluish haze over the eye. The eye may appear enlarged or bulging in chronic cases. Excessive tearing. Behavioral changes — lethargy, loss of appetite due to pain. Vision loss — bumping into things on the affected side. Acute glaucoma is a painful emergency
Tonometry ($50-$100) measures intraocular pressure — the key diagnostic test. Normal pressure is 10-25 mmHg; glaucoma readings exceed 25-30 mmHg. Gonioscopy ($100-$200) examines the drainage angle to determine if glaucoma is primary or secondary. Ophthalmoscopy evaluates retinal health and optic nerve damage. Average $100-$300
Emergency pressure reduction with IV mannitol and topical medications ($200-$500). Ongoing eye drops to control pressure cost $50-$200/month indefinitely. Laser surgery (cyclophotocoagulation) to reduce fluid production costs $1,500-$3,000 per eye. If the eye is blind and painful, enucleation (removal) costs $500-$1,500 and eliminates pain permanently. Average $50-$3,000
Emergency treatment + surgery or ongoing meds. Lifelong medication adds $600-$2,400/year.
Cocker Spaniels, Basset Hounds, Beagles, and Siberian Huskies have the highest rates of primary glaucoma.
Despite treatment, most dogs with primary glaucoma eventually lose vision. The second eye is affected within 2 years in 50% of cases.
No prevention for primary glaucoma. Prophylactic eye drops for the unaffected eye may delay onset. Regular eye exams for at-risk breeds.

Emergency treatment + surgery or ongoing meds.
Most comprehensive pet insurance policies cover glaucoma diagnosis, emergency treatment, surgery, and ongoing medications. Standard 14-day illness waiting period applies. Emergency glaucoma treatment and enucleation are typically covered without pre-authorization.
Primary glaucoma is a hereditary condition. Some policies exclude hereditary or congenital eye diseases entirely. Others cover them but with longer waiting periods. If you own a predisposed breed like a Cocker Spaniel, verify that hereditary eye conditions are covered before enrolling.
Glaucoma eye drops cost $50-$200/month indefinitely. Some policies cover ongoing prescription medications while others have limits on chronic medication coverage. Laser surgery ($1,500-$3,000) may actually be more cost-effective than years of daily drops.
When glaucoma hits the second eye (common within 2 years), some insurers treat it as a continuation of the same condition — meaning the deductible is already met. Others treat it as a separate occurrence. This distinction can mean hundreds of dollars difference in reimbursement.

My mother-in-law took her German boxer to the veterinary emergency room — $1,200 in tests, no answers. A different vet solved it in minutes with $8 pills.
That moment stuck with me. When you’re scared for your dog, you’ll pay anything. Some vets take advantage of that. I started digging into vet costs and pet insurance. The policies were confusing, the exclusions buried, the pricing impossible to compare. So I built the resource I wish existed. Real costs, real exclusions, plain speak. I’m not here to sell you a policy. I’m here so you don’t get blindsided.
