Cherry Eye Repair

Cherry eye — the red, fleshy bulge in the corner of your pet's eye — is a prolapsed tear gland that should be surgically repositioned rather than removed, preserving lifelong tear production.

Dogs and cats have a third eyelid (nictitating membrane) in the inner corner of each eye, and tucked within it is a tear gland called the nictitans gland. When the tissue anchoring this gland weakens, the gland pops out of position and becomes visible as a round, red, fleshy swelling — commonly called cherry eye. Beyond looking alarming, a prolapsed gland can become inflamed, dry out, and over time produce fewer tears, predisposing the eye to dry eye disease (keratoconjunctivitis sicca). Cherry eye repair at Dog & Cat Hospital Calabasas surgically tucks the gland back into its correct position, restoring both appearance and function.

Why It's Recommended

Cherry eye does not resolve on its own — the gland will not return to its pocket without surgery. Delaying treatment allows the exposed gland to become increasingly inflamed and reduces its long-term function. More importantly, this gland accounts for roughly 30–50% of the eye's total tear production; removing it (as was common in older practice) significantly increases the lifetime risk of dry eye disease. Modern surgical repair preserves the gland by repositioning it, which is why replacement rather than removal is now the strongly preferred approach. Surgery is recommended as soon as the prolapse is identified, before chronic inflammation sets in.

How the Procedure Works

Cherry eye repair is performed under general anesthesia with the eye lubricated and protected throughout. The most common technique is the pocket (envelope) method:

  • Small incisions are made in the conjunctival tissue above and below the prolapsed gland, creating a pocket
  • The gland is tucked into the pocket and the incisions are closed with fine absorbable sutures, securing the gland in its normal position beneath the third eyelid
  • No tissue is removed — the entire gland is preserved

Alternative techniques include a purse-string suture anchoring the gland or a combination approach in severe or recurrent cases. The surgeon selects the technique based on the degree of prolapse and gland condition. Both eyes may be addressed at the same time if prolapse is present bilaterally.

Preparation

A full ophthalmic examination is performed before surgery to assess gland health, rule out concurrent eye conditions, and evaluate whether any corneal irritation has developed from the prolapse. Pre-anesthetic bloodwork is run, particularly in animals with health conditions. Anti-inflammatory eye drops may be prescribed in the days before surgery to reduce gland swelling and improve the repair. Food is withheld the night before the procedure.

Recovery & Aftercare

Cherry eye repair is typically an outpatient procedure with a smooth recovery:

  • Days 1–7: e-collar worn to prevent rubbing; prescribed anti-inflammatory and antibiotic eye drops administered as directed
  • Week 1–2: mild swelling in the inner corner of the eye is normal and resolves within one to two weeks
  • 2–4 weeks: recheck exam confirms the gland is staying in place and the eye looks healthy

Reprolapse (the gland popping back out) can occur in a small percentage of cases, especially in highly predisposed breeds. If it happens, revision surgery is performed promptly. Breeds with very loose eyelid conformation — Bulldogs, Cocker Spaniels, Beagles, Basset Hounds, Shar-Peis — have higher rates of reprolapse than others.

Risks & What to Expect

Cherry eye repair has a good success rate, particularly when performed before the gland has been exposed and inflamed for a long time. The main risk is reprolapse, which occurs more frequently in brachycephalic (flat-faced) breeds and large-breed dogs. Revision surgery, sometimes using a different technique, addresses reprolapse effectively in most cases. Infection is uncommon, and the sutures used are absorbable so they do not need to be removed. Lifelong monitoring of tear production (Schirmer tear test) at wellness visits is recommended in breeds predisposed to dry eye, regardless of whether cherry eye surgery was performed.

Frequently Asked Questions

1Should I have cherry eye removed or repaired?
Repaired — always. Removing the third-eyelid gland eliminates roughly a third to half of the eye's tear-producing tissue, substantially increasing the risk of chronic dry eye disease for the rest of the pet's life. Modern surgical techniques successfully tuck the gland back in place without removing it.
2Can cherry eye go away on its own?
No — a prolapsed nictitans gland will not return to its pocket without surgery. The longer it remains prolapsed, the more inflamed it becomes and the harder it is to repair successfully, which is why early treatment is recommended.
3What breeds are most prone to cherry eye?
Bulldogs, Beagles, Cocker Spaniels, Basset Hounds, Shar-Peis, Lhasa Apsos, and Shih Tzus are among the most commonly affected dog breeds. Cherry eye also occurs in cats, most often in Burmese and other round-faced breeds.
4Does my dog need surgery right away for cherry eye?
The sooner the better. Prompt repair before chronic inflammation sets in gives the best chance of long-term success and preserves gland function. There is rarely a reason to wait more than a few days to a week once the prolapse is identified.
5Will my dog need surgery on both eyes?
The opposite eye is at elevated risk in predisposed breeds, and some pets do develop bilateral cherry eye either simultaneously or weeks to months apart. Both eyes can be repaired in a single anesthetic episode if both are prolapsed.
6How much does cherry eye surgery cost for a dog?
Cost varies depending on whether one or both eyes are treated and the technique required. A written estimate is provided at the pre-surgical exam.
7What if the cherry eye comes back after surgery?
Reprolapse occurs in a minority of cases, particularly in flat-faced breeds. Revision surgery using a complementary or different technique is typically successful, and the gland continues to be preserved rather than removed.
8Is my dog in pain from cherry eye?
The prolapsed gland itself is not acutely painful in the way a cut would be, but chronic exposure causes irritation, dryness, and discomfort over time. Most pets show increased eye rubbing and discharge. Surgery relieves this discomfort.
