Q: My vet says my cat has glaucoma and might lose the eye — how much is this going to cost? A: Anywhere from $30 a month for medication to about $1,800 for surgical removal of the eye, and which one applies depends entirely on how far the pressure damage has gone. Glaucoma in cats is sneakier than in dogs and often points to an underlying problem like chronic inflammation or even a tumor, so the workup is a real part of the cost.
Unlike dogs, where glaucoma is frequently inherited, feline glaucoma is usually secondary — caused by uveitis (eye inflammation) most often. Chronic feline uveitis is one of the leading causes of secondary glaucoma in cats, which is why your vet won’t just hand you eye drops and send you home.
- Diagnostic workup including pressure testing: $200–$600
- Medical management (pressure-lowering drops): $30–$90/month
- Ophthalmology consult: $150–$400
- Enucleation (surgical eye removal): $800–$1,800
- Feline glaucoma is usually secondary to another condition, so finding the cause is part of the cost.

| Recheck exams (each) | $60 | $180 | $110 |
Why Diagnosis Comes First
Glaucoma means high pressure inside the eye, and that pressure damages the optic nerve and causes pain. Measuring it takes a tonometer — a quick, painless instrument — but the bigger question is why the pressure is high. Because feline glaucoma is usually secondary, your vet needs to hunt for the cause: chronic uveitis, infection, a clot, or in some cases an intraocular tumor. That hunt may include bloodwork and imaging, pushing the workup to $200 to $600 or more.
It’s tempting to want to skip straight to drops. Don’t. If a tumor is driving the glaucoma, drops are a temporary patch on a serious problem, and you’d be spending money without addressing what’s actually happening.
Drops Buy Time; Surgery Solves It
For a recently affected eye that still has vision potential, pressure-lowering drops can preserve sight and comfort — but they’re a daily, lifelong commitment at $30 to $90 a month, and they don’t always keep up. A general vet visit for rechecks adds to that over time.
When an eye is blind and painful — which is unfortunately common by the time feline glaucoma is caught — enucleation (removing the eye) is the most humane and definitive answer. It ends the pain in one step, and cats adapt remarkably well to one eye. At $800 to $1,800, it’s also a one-time cost rather than an open-ended monthly bill, which makes it the more economical choice for many families in the long run.
A suddenly enlarged, cloudy, red, or obviously painful eye is an emergency. Acute glaucoma can permanently destroy vision within 24 to 48 hours if the pressure isn’t brought down fast. Squinting, pawing at the eye, and lethargy all signal pain. Don’t wait for a routine appointment — same-day care can sometimes save the vision in a freshly affected eye.
The Hidden Cost: Finding the Cause
Because something is usually driving feline glaucoma, you may end up treating two things at once — the glaucoma and its underlying trigger. If chronic uveitis is the culprit, that’s ongoing anti-inflammatory therapy. If a tumor is found, that’s a whole separate conversation that may overlap with our cat cancer treatment cost guide. Budgeting only for the eye, and not for the cause, is how owners get blindsided.
Can Pet Insurance Help?
Glaucoma is covered as an illness on comprehensive policies provided it isn’t pre-existing — and that’s the rub, since many cats have a history of eye inflammation that insurers may flag. If you insured early, a plan paying 80–90% makes both drops and surgery far more affordable. Weigh it with our pet insurance cost per month and is pet insurance worth it breakdowns.
For an uninsured surgical bill, CareCredit for vet bills spreads enucleation costs across monthly payments.
The Bottom Line
Cat glaucoma treatment costs $30 to $90 a month for drops or $800 to $1,800 for surgical eye removal, plus the workup to find what’s causing it. For a blind, painful eye, enucleation is often both the kindest and the most cost-effective path — a single fix versus endless drops that may not keep the pressure down anyway.
Frequently Asked Questions
Surgical eye removal for glaucoma typically costs $1,500–$1,800, while laser or implant procedures to preserve vision range from $800–$1,500 per eye. Initial diagnostic workup to confirm glaucoma and rule out underlying causes (ultrasound, gonioscopy, tonometry) usually adds $300–$500 to the total cost.
Most pet insurance plans cover glaucoma treatment if it's not a pre-existing condition, though coverage varies by policy and provider; expect 70–90% reimbursement after your deductible. Monthly eye drop medications ($30–$80) are often covered, but some policies exclude or limit coverage for chronic conditions or surgical eye removal, so review your specific plan terms.
Eye drops are typically the first-line treatment for newly diagnosed glaucoma if the eye still has vision potential, requiring daily administration and costing $30–$80 monthly for the lifetime of the cat. Surgery or eye removal becomes necessary when drops fail to control pressure, the eye becomes blind and painful, or when glaucoma is secondary to severe inflammation or tumors that drops cannot address.
