Cherry Eye in Cats

Cherry eye in cats, while less common than in dogs, can still pose a significant health concern for our feline companions. This condition, characterized by the protrusion of the third eyelid's gland, can lead to discomfort, redness, and other eye issues if not addressed properly. Early detection and treatment are crucial for the well-being of your cat, highlighting the importance of understanding this condition fully.

What is Cherry Eye in Cats?

Cherry eye in cats, also known as nictitans gland prolapse or third eyelid gland prolapse, is a condition where the gland of the third eyelid (nictitating membrane or "haw") protrudes or becomes visible in the corner of the eye, resembling a small red or pink cherry. 

The third eyelid plays a role in protecting and lubricating the eye, and it contains a gland that produces a portion of the tear film. When the gland prolapses, it can lead to irritation, inflammation, and discomfort for the cat. 

What Causes Cherry Eye in Cats?

The exact cause of cherry eye in cats is not well understood, but it is believed to be related to a combination of genetic factors, anatomical weaknesses, and underlying eye issues. Here are some potential contributing factors:

• Genetic predisposition: Some cat breeds may have a higher genetic predisposition to developing cherry eye. Breeds such as Burmese, Persian, and Siamese cats are reported to be more prone to this condition.
• Weak connective tissue: The gland of the third eyelid is normally held in place by connective tissue and muscles. In cats with cherry eye, there may be a weakness in these supporting structures, allowing the gland to prolapse or pop out of its normal position.
• Underlying eye problems: Certain eye conditions or diseases, such as conjunctivitis or corneal ulcers, can cause irritation and inflammation in the eye. This inflammation may contribute to the prolapse of the third eyelid gland.
• Environmental factors: While less common, environmental factors such as allergens or foreign bodies irritating the eye may also contribute to the development of cherry eye.

It's important to note that cherry eye is not typically associated with infections, and it is not contagious to other cats or animals. 

Symptoms of Cherry Eye in Cats

The symptoms of cherry eye in cats may vary in severity, but the most common and prominent symptom is the presence of a pink or red, fleshy protrusion coming from the inner corner of a cat's eye. This protrusion is often mistaken for a small, cherry-like mass, which is how the condition got its name. However, additional symptoms and complications may occur, including:

• Dry eye (keratoconjunctivitis sicca)
• Corneal ulceration
• Irritation
• Inflammation of the cornea (keratitis)
• Inability to close the eye
• Occasional eye discharge

Early Stage Cherry Eye in Cats

Early-stage cherry eye in cats may present with subtle symptoms and may not be as noticeable as the advanced stages of the condition. Some signs of early-stage cherry eye in cats may include:

• Occasional or intermittent protrusion of the glands of the third eyelid
• Slight redness or swelling
• Excessive blinking or squinting
• Occasional eye discharge

Can Cherry Eye Go Away on Its Own?

Cherry eye typically does not go away on its own. While it's possible for the gland of the third eyelid to occasionally return to its normal position temporarily, it often pops out again, especially in more severe cases. Cherry eye is caused by a weakness in the connective tissue that holds the gland in place, and this weakness doesn't usually resolve without intervention.

In some mild cases, the gland may spontaneously return to its normal position, but it's not a reliable or long-term solution. Leaving cherry eye untreated can lead to ongoing discomfort, eye irritation, and an increased risk of complications such as dry eye (keratoconjunctivitis sicca) or corneal ulcers.

Veterinary intervention is typically recommended for cherry eye. Surgical correction is the most effective and long-lasting treatment option, where the gland is repositioned and secured in place to prevent further prolapse. 

How Veterinarians Diagnose Cherry Eye in Cats

Veterinarians typically diagnose cherry eye in cats through a combination of visual examination and sometimes additional tests to assess the extent of the condition and identify any underlying causes. Here's how veterinarians diagnose cherry eye in cats:

The most obvious sign of cherry eye is the protrusion of the gland of the third eyelid (nictitans gland) in the corner of the cat's eye. Veterinarians can often diagnose cherry eye by observing this characteristic pink or red mass. They may use a specialized light source or magnifying tools to get a closer look.

The vet will assess the overall condition of the affected eye and check for any associated symptoms like inflammation, irritation, or discharge. They may also evaluate the other eye for comparison.

In some cases, additional diagnostic tests like tear production tests or cultures may be performed to assess the overall eye health or rule out other conditions.

What common ocular tests are performed to diagnose cherry eye in cats?

When diagnosing cherry eye in cats, veterinarians often rely on a few key ocular tests to ensure a comprehensive assessment of eye health. Here are the common tests performed:

• Tonometry: This procedure measures the intraocular pressure within your cat's eye. To execute this, a veterinarian first numbs the surface of the eye with special drops. Then, a delicate instrument, resembling a pen, lightly touches the eye's surface. This step is vital for identifying potential pressure-related issues.

• Schirmer’s Tear Test: Essential for detecting tear production levels, particularly in cases where dry eye might be a concern, this test involves placing a small strip of paper inside the lower eyelid. The paper remains in the eye for about a minute, during which it absorbs tears. The amount of moisture on the paper indicates tear production efficiency, an important factor in diagnosing conditions like cherry eye.

These tests offer critical insights into your cat's ocular health and help tailor the most effective treatment plan.

Treatment Options for Cherry Eye in Cats

Cherry eye in cats should not be ignored, as it can lead to complications if left untreated. Fortunately, there are several treatment options available:

• 1. Surgical Repair:
  The most common and effective treatment for cherry eye in cats is surgical repair. During the procedure, a veterinarian will reposition the prolapsed gland and secure it in its normal position. This surgery is typically successful in resolving the issue. The cost of surgery to correct cherry eye in cats can vary widely depending on several factors. On average, you can expect to pay the bill ranging from $300 to $500 or even more.
  
  
  

  Recovery and Management Process After Surgery

  After your cat undergoes surgery for cherry eye, the recovery period typically spans about a week. During this time, it's not uncommon to notice some mild swelling around the surgical site. However, this swelling usually subsides within a few days.

  Post-Surgery Expectations:

  • Swelling: Any swelling should gradually diminish throughout the week following the procedure.
  • Monitoring: Keep an eye on your cat for any signs of the gland protruding again, as this can sometimes occur.

  Managing Complications:

  The primary concern after surgery is the possibility of the third eyelid gland prolapsing once more. If this happens, it's critical to contact your veterinarian promptly. They might suggest a second surgical procedure or a referral to a veterinary ophthalmologist for specialized care.

  Tips for a Smooth Recovery:

  • Follow-Up Appointments: Ensure that you attend all scheduled postsurgical check-ups to monitor your cat’s healing progress.
  • Medication: Provide any prescribed medication, such as anti-inflammatory drugs or antibiotics, exactly as directed by your vet.
  • Restrict Activity: Limit your cat's physical activity to prevent any strain on the eye.

  By adhering to these guidelines, you can support your cat's recovery and reduce the likelihood of further complications.

• 2. Medications:
  In some cases, a veterinarian may prescribe anti-inflammatory medications to reduce swelling and discomfort in the affected eye. However, this is usually a temporary measure and may not provide a long-term solution.
• 3. Massage and Warm Compresses:
  Some veterinarians may recommend gentle massage and warm compresses to help reduce swelling in mild cases of cherry eye. However, these methods are often not sufficient for severe cases.

How Can I Prevent Cherry Eye in My Cat?

Preventing cherry eye in cats can be challenging because it is often related to genetic factors and anatomical predisposition. However, there are some steps you can take to potentially reduce the risk of your cat developing cherry eye or minimize the likelihood of recurrence if your cat has had the condition before:

Choose Breeds Wisely: If you are getting a cat from a breeder, consider selecting a breed that is less prone to cherry eye. Some breeds, like Burmese and Siamese cats, are more predisposed to this condition.

Regular Eye Care: Pay attention to your cat's eye health by routinely checking for any signs of irritation or inflammation. If you notice any unusual symptoms, consult your veterinarian promptly. Timely removal of cat tear stains.
