Cherry Eye in Dogs and Cats: What Every Pet Owner Should Know

Cherry eye (or prolapsed tear gland of the third eyelid), is when the gland of the third eyelid protrudes out and appears as a red-pink colored mass in the medial corner of the eye. The gland is then unable to circulate blood properly, becomes swollen and does not produce tears properly.  This then leads to irritation, corneal ulcers, and/or dry eye. The good news is, the condition is surgically correctable.

This guide breaks down what cherry eye is, why it happens, whether it can resolve without surgery, what the repair procedure actually does (and why removing the gland is discouraged), and what pet owners can expect for cost, outcomes, and recovery. If your dog or cat has a red, swollen mass in the corner of their eye, understanding this condition can help you make a confident, informed decision alongside your veterinarian.

Understanding Cherry Eye: More Common Than You'd Think

Dogs and cats have a third eyelid — a thin membrane tucked in the inner corner of the eye called the nictitans.  Inside the nictitating membrane is a small gland which produces about 30% of the water which makes up tear film.  So, it’s important to maintain the function of this gland to keep the eye lubricated.  

When the connective tissue holding that gland in place weakens, the gland can slip out of position and pop up over the edge of the third eyelid. The result is a smooth, reddish-pink mass in the corner of the eye — the "cherry" that gives the condition its name.

The underlying cause isn't fully understood, but veterinary ophthalmologists believe it stems from a congenital weakness in the tissue that anchors the gland in place, as described by the American College of Veterinary Ophthalmologists. Once that attachment breaks down, it can't simply repair itself, which is why the prolapse tends to happen suddenly and why it needs a veterinarian's attention rather than watching and waiting.

Cherry eye can affect either eye, and if a dog experiences it in one eye, there's a meaningfully higher chance it will happen in the other eye at some point too — the two prolapses often don't occur at the same time. Most dogs are first affected quite young, typically between the ages of six months and two years. A large-scale study from the Royal Veterinary College's VetCompass Programme, which followed more than 905,000 dogs, found that dogs under one year old face nearly 11 times the risk of dogs between two and four years old.

Which Breeds Are Most at Risk

Certain breeds carry a dramatically higher risk. That same RVC VetCompass research — the largest exploration of cherry eye ever conducted — found that about 1 in every 500 dogs is affected each year overall, but the numbers climb sharply for specific breeds: Neapolitan Mastiffs (nearly 34 times the risk of a crossbred dog), English Bulldogs (24 times), Lhasa Apsos (12 times), American Cocker Spaniels (nearly 12 times), and Puggles (9.5 times) all rank among the highest-risk breeds. Flat-faced (brachycephalic) breeds in general — including French Bulldogs and Boston Terriers — face almost 7 times the risk of dogs with a medium-length skull, and purebred dogs overall carry about 1.4 times the risk of mixed-breed dogs. Beagles, Pekingese, Mastiffs, and Poodles are also frequently affected, and while cherry eye is far less common in cats, it can occur — most notably in Burmese cats.

Can Cherry Eye Resolve Without Surgery?

This is one of the most common questions we hear, and it deserves an honest, direct answer: in most cases, no — but there are exceptions worth understanding.

In very early, mild cases, a veterinarian may try a short course of anti-inflammatory medication or eye drops, to see if a very minor or intermittent prolapse resolves on its own. Some case reports in the veterinary literature describe early-stage prolapses managed this way with oral and topical anti-inflammatories. However, once the gland has fully prolapsed and stayed out of position, it will not reposition itself, and waiting only furthers complications.  Delaying treatment gives the exposed gland more time to become irritated, swollen, or infected, which can actually make surgical repair more difficult later and decrease chances of success.. If you're seeing conflicting advice online about home remedies or "wait and see" approaches, the safest path is to have your veterinarian examine the eye first — what looks like a mild, self-resolving case to an untrained eye may already need surgical correction.

What Cherry Eye Repair Does — and Doesn't Do

This is the part many pet owners get wrong, often because it seems intuitive: if a gland has slipped out of place, why not just remove it?

The short answer is that removing the gland is no longer considered standard of care and is only used as the last resort. That small gland tucked in the third eyelid produces the water component of tear film.  If the other tear producing tissues become compromised or simply become inadequate, as is often the case in older dogs, you are left with an eye that is permanently short on tears — a condition called keratoconjunctivitis sicca, or “dry eye” as we know it. Dry eye isn't a minor inconvenience; it's uncomfortable, often requires lifelong medication, and in severe, poorly managed cases can cause ulcers and threaten vision.

So instead of removing the gland, the surgical goal is to put it back where it belongs and keep it there. The most common technique — called the Morgan Pocket Procedure — creates a small pocket in the tissue beneath the gland and tucks it back into its normal anatomical position, where it's held in place as the tissue heals around it. Some surgeons combine this with an additional tacking technique for extra stability, particularly in breeds prone to recurrence. The exact approach is typically decided during surgery, once the surgeon can evaluate the tissue directly.

It's also worth being precise about the limits of repair. A dog that also has an underlying eyelid or cartilage abnormality — a fairly common contributor to prolapse in some breeds — may be at higher risk of the gland prolapsing again unless that underlying issue is addressed at the same time. And even after a technically successful repair, there is a lifelong, if small, risk of dry eye developing later — which is exactly why regular veterinary eye checks matter long after the surgery itself is done.

Prognosis: What the Data Shows

The numbers support what veterinary ophthalmologists have been saying for years: repair, not removal, is the right call, and it works well.

A 2018 evidence review published in the peer-reviewed journal Veterinary Sciences, which pooled outcomes across multiple studies and nearly 1,000 dogs, found an overall reprolapse rate after the Morgan pocket procedure of about 3 percent, with most individual studies reporting failure rates somewhere between 0 and 12.5 percent. Separately, the American College of Veterinary Ophthalmologists cites an overall success rate of approximately 92 percent for surgical replacement techniques performed by a specialist, meaning recurrence occurs in less than 8 percent of cases.

Certain breeds do carry a higher chance of recurrence regardless of technique — Neapolitan Mastiffs, English Bulldogs, Shar-Peis, and Newfoundlands are among those noted in the veterinary literature as more prone to reprolapse, with unpublished survey data on Neapolitan Mastiff owners cited in that review reporting a repair failure rate approaching 40 percent in that breed specifically. This is one reason your veterinarian may recommend a particular technique, or discuss the possibility of referring to an ophthalmologist, based on your pet's breed and eyelid conformation.

How Much Does Cherry Eye Repair Cost?

Cost is one of the first questions most pet owners have, so it's worth addressing directly rather than leaving you to guess. Nationally, cherry eye surgery for dogs commonly ranges from around $300 on the lower end to $2,500 on the higher end, depending on factors like whether one or both eyes are affected, the technique used, anesthesia and monitoring needs, and geographic location.

That's a wide range because "cherry eye surgery" isn't one standardized procedure — a straightforward single-eye repair in a healthy young dog costs meaningfully less than a bilateral repair, a case involving significant tissue damage from a delayed diagnosis, or a procedure that requires more complex reconstruction. Rather than quote a single number that may not reflect your pet's specific situation, we review each case individually so you get an accurate picture before moving forward. If you'd like guidance on what to expect for your pet, text or call our team and we'll walk you through it.

Aftercare and Recovery

Recovery from cherry eye repair is generally straightforward and comparable to recovery from other routine outpatient eye procedures.   

Pets go home the same day with a recommendation for an E-collar (cone) to prevent rubbing or scratching at the eye, which is the single biggest risk to a successful repair in the first days after surgery. Your veterinarian will typically prescribe an antibiotic and/or anti-inflammatory eye ointment or drops for one to two weeks, along with a follow-up exam to confirm the eye is healing well and the gland has stayed in place. Some mild redness, swelling, or third-eyelid puffiness for 5-7 days immediately following surgery is normal and generally resolves on its own.

Most dogs and cats are back to their normal selves within one to two weeks, though the eye area should be watched closely during that window. Contact your veterinarian if you notice the mass reappearing, if the eye seems painful, if there's significant discharge, or if your pet won't stop pawing at the eye despite the E-collar — any of these can signal early recurrence or a developing complication that's easier to address sooner rather than later.

Frequently Asked Questions

1. Is cherry eye painful for dogs and cats?
   Cherry eye itself typically looks more alarming than it feels in the early stages, but the exposed gland can become irritated, dry, or infected the longer it's left untreated, which does become uncomfortable over time.

2. Can cherry eye come back after surgery?
   Yes, recurrence is possible and will depend on the individual patient’s conformation, duration of prolapse, and any underlying comorbidities— most veterinary sources cite recurrence in roughly 3 to 8 percent of cases, with certain breeds carrying a somewhat higher risk.

3. Does pet insurance cover cherry eye surgery?
   Coverage varies by provider and policy, and some insurers treat cherry eye as a breed-related or pre-existing condition depending on when the policy started. Check with your specific insurer, and enroll before symptoms appear whenever possible.

4. Can I wait to see if it goes away on its own?
   It's not recommended. A true prolapse typically doesn't self-correct, and delaying treatment can make the eventual repair more complicated and lower the chances of success.

5. Is cherry eye repair the same as removing the gland?
   No — modern veterinary practice repositions the gland rather than removing it, specifically to protect long-term tear production and avoid chronic dry eye.

Where Spay Neuter Vets Fits In

Spay Neuter Vets is a focused outpatient surgical center in Alpharetta, Georgia, and cherry eye repair is one of the procedures our surgeons perform routinely. Because cherry eye is a straightforward, visible diagnosis, you don't need a referral or a prior vet visit to bring your pet in — the sooner, the better. Waiting allows the everted cartilage to set further out of place, which lowers the chances the gland will stay tucked once repaired.

When you contact us, we'll take a brief history — how long the prolapse has been present, whether it's been repaired before, and any other eye issues — to determine the best path forward for your pet. If your veterinarian has already examined your pet or recommended surgery, just let us know when you reach out; that history helps us move faster. In more complex cases, such as multiple prior repairs or additional eyelid abnormalities, we may recommend a specialist consult alongside our care.
