Canine Meibomian Gland Tumors

Tumors can grow from sebaceous glands in the eyelids.

Meibomian gland tumors occur in a dog's eyelids. They're quite common, especially in older dogs.

What Causes Meibomian Gland Tumors in Dogs?

The Meibomian glands provide the eyes with oily moisture that keeps the tear film on the cornea stable. They are sebaceous glands, which are also found in other areas of the skin.

Tumors in the Meibomian glands result in bumps along the inside or edges of the eyelids. They may pop outward or turn inward and rub on the cornea.

Meibomian gland tumors in dogs are usually benign (non-cancerous), so they don't typically spread or move to other areas of the body.

Canine meibomian gland tumors can become irritated, painful, and even infected, or they can cause corneal ulcers or conjunctivitis.

In dogs, Meibomian gland tumors usually grow slowly.

Signs of Meibomian Gland Tumors in Dogs

The tumor is visible along an edge of the eyelid as a firm bump. The eye may have excessive tearing, and if the tumor is rubbing on the cornea, the dog may paw at the eye or rub his head on items.

Treatment of Meibomian Gland Tumors in Dogs

Meibomian gland tumors must be removed surgically. It can be done with a blade or cryosurgery (freezing). Removal requires general anesthesia for the dog. If the tumor is very large, the result may be a slightly deformed eyelid.

After surgery, the dog must not be allowed to rub their face on the ground or paw at it, so an E-collar will most likely be necessary. Eye drops for inflammation and antibiotics may be prescribed.

If the eye itself has secondary issues like corneal ulcer or conjunctivitis, that will need to be treated after surgery as well.
