Why doesn't the third eyelid go away from my cat? - briefly

The third eyelid in cats, known as the nictitating membrane, can remain visible due to several reasons, including irritation, infection, or underlying health issues. It is crucial to consult a veterinarian for a proper diagnosis and treatment.

The third eyelid serves as a protective barrier for the eye, and its persistent visibility may indicate an underlying problem that requires medical attention. Common causes include:

  • Conjunctivitis: Inflammation or infection of the membrane surrounding the eyeball.
  • Dry eye: Insufficient tear production leading to irritation.
  • Trauma: Injury to the eye or surrounding area.
  • Foreign body: Presence of an object in the eye.
  • Eyelid abnormalities: Issues such as entropion or distichiasis.

Prompt veterinary care is essential to address the root cause and prevent potential complications. Regular check-ups and maintaining good eye hygiene can help in the early detection and management of such conditions.

Why doesn't the third eyelid go away from my cat? - in detail

The third eyelid, also known as the nictitating membrane or haw, is a thin, translucent or opaque membrane that can be observed in the inner corner of a cat's eye. It serves several important functions, including protecting the eye from debris, providing additional moisture, and offering a layer of defense against potential injuries. However, when this third eyelid becomes persistently visible or does not retract properly, it can indicate an underlying issue that requires attention.

One of the most common reasons for a persistently visible third eyelid in cats is a condition known as "cherry eye." This occurs when the gland of the third eyelid prolapses or pops out of its normal position. Cherry eye is more commonly seen in certain breeds, such as Bulldogs, Beagles, and Cocker Spaniels, but it can affect any cat. This condition is usually not painful but can lead to irritation and potential infection if left untreated. Veterinary intervention, often involving surgical correction, is typically required to address cherry eye.

Another possible cause is an eye infection or irritation. Infections, allergies, or foreign bodies in the eye can cause inflammation, leading to the third eyelid becoming more prominent. In such cases, the third eyelid may remain partially or fully visible as a protective response. Treatment usually involves addressing the underlying cause, which may include antibiotics, anti-inflammatory medications, or removal of the irritant.

Dehydration can also cause the third eyelid to become more visible. When a cat is dehydrated, the body may conserve moisture by reducing tear production, leading to a dry eye. The third eyelid may then become more prominent as it attempts to provide additional moisture. Ensuring proper hydration and addressing any underlying health issues that may be causing dehydration is essential.

Nutritional deficiencies, particularly in vitamin A, can also affect the health of the eyes and the third eyelid. A diet lacking in essential nutrients can lead to various eye problems, including a persistently visible third eyelid. Providing a balanced diet or supplements as recommended by a veterinarian can help alleviate these issues.

In some cases, the third eyelid may become more visible due to aging or natural wear and tear. As cats age, the muscles and tissues around the eye can weaken, leading to a more prominent third eyelid. While this is often a normal part of aging, it is still important to monitor the cat's eye health and consult a veterinarian if there are any concerns.

It is crucial to note that a persistently visible third eyelid can sometimes be a sign of a more serious underlying condition, such as an eye tumor or glaucoma. Regular veterinary check-ups and prompt attention to any changes in the cat's eyes are essential for maintaining overall eye health.

In summary, a persistently visible third eyelid in cats can be caused by a variety of factors, including cherry eye, infections, dehydration, nutritional deficiencies, aging, or more serious underlying conditions. If you notice that your cat's third eyelid is consistently visible or does not retract properly, it is important to consult with a veterinarian to determine the underlying cause and appropriate treatment. Early intervention can help prevent potential complications and ensure the long-term health of your cat's eyes.
