Prolapse of the third eyelid gland in animals: what is it, what to look for, and how is it treated?

Animals, unlike humans, have not 2 but 3 eyelids. The third eyelid is located in the inner corner of the eye and is almost invisible. It is needed to protect the organ of vision and produces up to 40% of the total volume of tear fluid in the eye. It is also responsible for the distribution of tear fluid in the eye.

How to recognize prolapse of the third eyelid gland?

A prolapsed third eyelid gland looks like a rounded formation in the inner corner of the eye - between the cornea and the third eyelid. In a pathological state, this gland is red in color and causes discomfort, so the pet rubs the eye with its paw. Intense tearing may occur as a result of the inflammatory process.

Why does the gland of the third eyelid fall out and how to repair the prolapse?

The cause of the pathology may be a breed predisposition. It is most often found in dogs: Sharpeys, pugs, bulldogs, beagles, Pekingese, and Cane Corso. However, the disorder can also occur in cats with flattened pasterns: British, Scottish, Persian, exotic shorthair, etc. The following factors can also cause prolapse:

• Allergic reaction.
• Trauma to the eye.
• Chronic conjunctivitis.
• Foreign body in the eye.
• Adenoma of the third eyelid.
• Overgrowth of lacrimal gland tissue.

The only effective way to cure an animal with a prolapsed third eyelid is to perform surgery. The surgical procedure involves a veterinarian-ophthalmologist making 2 miniature incisions around the inflamed gland, hiding it inside the formed "pocket" and suturing it.

The recovery period is about 10 days. During this time, the inflammation is completely resolved, and the third eyelid returns to its natural position. To prevent bacterial infection, a veterinary ophthalmologist can prescribe antibiotic eye drops or ointment and special anti-inflammatory drugs to help your pet's condition return to normal as soon as possible.

Do not treat lacrimal gland prolapse in a dog or cat on your own. Contact an Animal Clinic specialist and the problem will be solved quickly and safely for your four-legged friend.
