Glaucoma in dogs is a painful emergency - medications cost $50-$200/month and surgery runs $1,500-$3,000 per eye. Increased eye pressure damages the optic nerve and retina, causing permanent blindness within hours to days if untreated. Most dogs eventually lose vision despite treatment.
Glaucoma occurs when aqueous humor can't drain, building pressure that damages the optic nerve and retina. Primary glaucoma is inherited with a malformed drainage angle. Secondary glaucoma results from lens luxation, uveitis, or tumors. Primary glaucoma is inherited and bilateral
Red, painful eye with squinting or light sensitivity. Dilated pupil unresponsive to light. Cloudiness or bluish haze. Enlarged eye in chronic cases. Excessive tearing. Lethargy and appetite loss from pain. Vision loss - bumping into objects. Acute glaucoma is a painful emergency
Tonometry ($50-$100) measures intraocular pressure. Normal is 10-25 mmHg; glaucoma exceeds 25-30 mmHg. Gonioscopy ($100-$200) determines if primary or secondary. Ophthalmoscopy evaluates retinal and optic nerve damage. Average $100-$300
Emergency pressure reduction with IV mannitol and topical meds ($200-$500). Eye drops cost $50-$200/month long-term. Laser surgery costs $1,500-$3,000 per eye. Enucleation for blind painful eyes costs $500-$1,500 and eliminates pain. 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 policies cover diagnosis, emergency treatment, surgery, and ongoing meds. Standard 14-day illness waiting period applies. Emergency care and enucleation are typically covered without pre-authorization.
Primary glaucoma is hereditary. Some policies exclude hereditary or congenital eye diseases entirely; others cover with longer waiting periods. If you own a predisposed breed like a Cocker Spaniel, verify coverage before enrolling.
Eye drops cost $50-$200/month indefinitely. Some policies limit chronic medication coverage. Laser surgery ($1,500-$3,000) may be more cost-effective than years of daily drops.
When glaucoma hits the second eye (within 2 years), some insurers treat it as continuation of the same condition - deductible already met. Others treat it separately. This 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, you'll pay anything - and some vets price accordingly. I dug into vet costs and insurance. Confusing policies, buried exclusions, impossible to compare. So I built the resource I wish existed: real costs, real exclusions, plain language. Not here to sell you a policy. Here so you don't get blindsided.
