Key Takeaways
Along with a visible red mass, cherry eye in dogs causes eye irritation, tearing, and inflammation.
It can often be caused by genetics, age, and eye conditions involving trauma, infections, allergies, and inflammation.
The most reliable mode of treatment for cherry eye in dogs is surgical correction, preferably the pocket method.
Summary
Cherry eye is the name for an eye condition that refers to the prolapse of the third eyelid gland.
Dogs have a protective layer in their eyes that shields them from dust and debris. This third eyelid, called the nictitating membrane, contains a specialized tear gland responsible for tear production. When this third eyelid gland’s tissues weaken, the gland itself may prolapse.
This causes a red, swollen mass to appear at the corner of the eye, hence the name cherry eye. Cherry eye can affect one or both eyes.
Clinical Signs
The main symptom is a visible, smooth, and red or pink mass protruding from the inner corner of the eye. This mass closely resembles a cherry. Other symptoms our veterinarians observe include:
Frequent squinting and blinking
Discharge or tearing
Pawing or rubbing at the eye
Swelling and inflammation
Sensitivity to bright light
Causes
Cherry eye in dogs is caused by weakness in the tissue that holds the third eyelid gland in place. When the tissue fails to support the gland, it will slip out.
This eye condition is largely inherited. Brachycephalic breeds, toy breeds, and dogs with excess facial skin are at risk of cherry eye. This is mainly due to their shallow eye sockets, protruding eyes, and heavy facial skin. Common breeds at risk include: Beagles, Great Danes, Pugs, and Cane Corsos.
Cherry eye is common in pups under 2 years old because their connective tissues are still developing, including the retinaculum, the tissue holding the tear gland.
It can also be caused by accidents or animal fights that can tear or stretch the fibrous ligaments anchoring the third eyelid gland in place.
Other significant conditions include conjunctivitis, eye infections, and eye allergies. The resulting inflammation enlarges the tear gland and makes it flip outward.
The UAE’s hot climate may also contribute to eye irritation in many dogs, especially brachycephalic breeds, which are popular in the country. Environmental factors such as sand, dust, and dry air may trigger severe eye inflammation, prompting the third eyelid gland to pop out.
Potential Complications
If left untreated, cherry eye in dogs can lead to conditions such as dry eye syndrome, corneal ulcers, secondary infections, surgical problems, and even vision loss.
How is cherry eye in dogs diagnosed?
It’s primarily diagnosed by visual inspection for a prolapsed tear gland. Our ophthalmologists may perform an eye stain test, Schirmer tear test, and tonometry to rule out other eye conditions.
Eye stain test: Our team gently applies a special orange dye to the eye and washes away the excess. We’ll shine a blue light on the area to highlight any scratches or ulcers.
Schirmer tear test: We use a sterile, absorbent paper strip with a notch and a millimeter scale. This measures tear production in your dog's eye to check for keratoconjunctivitis sicca, or dry eye.
Tonometry: This test measures the dog’s intraocular pressure, helping to rule out conditions such as glaucoma.
Treatment
Cherry eye surgery is the only permanent treatment. Medications and supportive care will complement the treatment process.
Surgery
The most reliable way to treat cherry eye is to reposition the tear gland, preserving its function. This is called the pocket method or the Morgan pocket technique. It works by creating a small pocket in the conjunctiva to hold the displaced gland.
The gland is gently tucked into this pocket and stitched in place with dissolvable sutures, holding it securely. This safely preserves the gland’s function while preventing chronic dry eye.
Another possible procedure is the tacking method, which involves creating a permanent suture to secure the gland in its normal position within the eye socket.
Non-Surgical Treatments
Medication can be used to temporarily provide relief and reduce swelling. This will include anti-inflammatory and antibiotic drops or ointments. However, medication alone cannot fully cure cherry eye. These are used only to manage the condition, especially in early cases.
Post-Surgical Care
After surgery, special care is essential to ensure a smooth recovery and prevent recurrence. We prescribe anti-inflammatory or antibiotic eye drops to reduce swelling and treat infections. Elizabethan collars will also be required to help stop your dog from scratching or pawing at the area.
How much does treatment cost?
While it depends on a case-by-case basis, cherry eye surgery costs about AED 3,500 to AED 4,500. The exact costs may vary based on your dog’s breed, weight, and the severity of the condition.
Recovery Timeline
If your dog has undergone surgery, then here’s what to expect with the recovery process.
Days | What to Expect |
|---|---|
1 to 7 | The eye may still appear red and swollen, requiring your close monitoring and supervision. This is a high-risk period that will need medication, E-collars, and restricted activity. |
7 to 10 | The swelling should subside during this period, with continuous healing present. Activity must still be restricted, and medications should be given as prescribed. |
10 to 14 | Follow-up visits to check the progress of your dog’s cherry eye treatment. This will confirm if the gland is securely in place. Other recommendations and supportive therapies will be advised. |
When to See a Specialist
This eye condition is not always an emergency, but it should be checked by a veterinarian as soon as possible. A veterinary ophthalmologist may be recommended if:
The gland keeps prolapsing even after surgery
Your dog belongs to the breeds commonly prone to cherry eye
The cartilage of the third eyelid is bent or deformed
Your dog’s cherry eye has been left untreated for months or years
Preventive Tips
Managing allergies and eye conditions is a significant help. Early signs such as mild redness, irritation, or discharge should be checked by a professional before they become serious.
"Closely monitor your dog’s behavior. If you notice pawing, scratching, or squinting, then these are significant signs of eye irritation," Dr. Salome says. She also recommends keeping an eye on your dog when they play with other pets, since they can get rough.
"A good practice is to clean the house weekly, especially focus on the spaces your dog stays," says Dr. Salome. Schedule annual wellness exams to examine every aspect of your dog’s health, including their eyes.
"Cherry eye might look worring, but it can be treated with the right approach and gentle care."

The good news is that cherry eye in dogs is manageable and treatable. With the right diagnosis, surgical technique, and post-care, your best friend can regain their comfort and experience clear vision all throughout.
