Cats are resilient creatures with expressive eyes that tell us a lot about their health. But when something unusual appears — like a red, swollen bump in the corner of the eye — it can be alarming. This condition, commonly known as cherry eye, may sound serious, but understanding it can help you take the best care of your feline friend.
What Is Cherry Eye?
Cherry eye happens when the third eyelid gland — a small but important tear gland located in the inner corner of a cat’s eye — prolapses, or pops out of its normal position. This exposed gland appears as a red or pink, fleshy lump resembling a cherry (hence the name).
A cat’s third eyelid is crucial for eye health because it helps produce tears and protects the delicate surface of the eye.
What Causes Cherry Eye?
The exact cause isn’t always clear, but most experts think it happens because of a weakness in the connective tissue that holds the gland in place. Some common factors include:
Genetic Predisposition
- Certain breeds, such as Himalayans, Persians, and Burmese cats, may be more prone to cherry eye.
- While less common in cats than in dogs, hereditary factors can still play a role.
Inflammation or Injury
- Eye irritation, trauma, or chronic inflammation may contribute to the gland slipping out of position.
- Allergies can also weaken the tissues around the eye.
Weakened Support Tissues
- With age or repeated irritation, the tissues holding the gland can become less secure.
Recognizing the Signs
Cherry eye is fairly noticeable because of its appearance, but here’s what to look for:
Key Symptoms
- Red or pink mass at the inner corner of the eye
- Excessive tearing or discharge
- **“Irritated” look in affected eye
- Rubbing or pawing at the eye
- Dry eye over time if tear production is compromised
The condition typically affects only one eye, but it can occur in both eyes.
How Is Cherry Eye Diagnosed?
A veterinarian will:
- Examine your cat’s eye to confirm the prolapsed gland.
- Check tear production, as this gland contributes significantly to the production of healthy tears.
- Possibly use staining or pressure tests to assess corneal health.
Cherry eye often looks unmistakable, but a vet exam confirms the diagnosis and rules out other eye problems.
Treatment Options
Unlike minor irritations that go away on their own, cherry eye usually requires professional care. Here’s how it’s typically handled:
Surgical Replacement
- The most effective approach is to tuck the gland back into place and secure it so it stays in place.
- This helps preserve tear production and reduces the risk of dry eye later in life.
Why Not Remove It?
- In the past, veterinarians sometimes removed the gland entirely.
- But this is NOT recommended now because it can lead to insufficient tear production — a condition called keratoconjunctivitis sicca (dry eye).
Medical Management
- Anti-inflammatory eye drops or ointments may be used before surgery to reduce swelling.
- In mild, short-term cases, a vet might start with medication, but surgery is often necessary if the gland keeps recurring.
Caring for Your Cat After Surgery
Successful surgery is only part of the journey — postoperative care makes a big difference.
Aftercare Tips
- Prevent your cat from scratching the eye (an Elizabethan collar can help).
- Follow your vet’s instructions for eye drops or ointment.
- Attend all follow-up appointments to ensure healing is on track.
Most cats recover well and regain normal tear production.
Is Cherry Eye Serious?
Cherry eye isn’t usually life-threatening, but it can become serious if left untreated. Without proper tear production, the cornea may dry out, which can cause:
Early detection and treatment are key to maintaining your cat’s comfort and ocular health.
Final Thoughts
Cherry eye might look concerning, but with prompt veterinary care, most cats recover fully and continue to thrive. If you notice a red mass near your cat’s eye or changes in how they blink or tear, don’t wait — make an appointment with your vet.
Healthy eyes make for a happy cat — and now you’re better prepared to spot trouble early.
