Meibomian Gland Tumors in Dogs: Symptoms, Causes, and Care Tips

Meibomian gland tumors are small growths that develop along a dog’s eyelid margin, typically benign and slow-growing. These growths form when the meibomian gland, which produces part of the tear film, becomes clogged or irritated. Although generally non-cancerous, meibomian gland tumors can sometimes cause discomfort, leading to secondary eye issues if left untreated.

What Causes Meibomian Gland Tumors?

The exact cause of meibomian gland tumors is not fully understood, but they often result from blockages or changes in the gland that lead to small cyst-like growths. These tumors are more common in older dogs, as aging can affect gland function. Environmental factors, such as exposure to dust or pollen, may contribute to irritation that increases the likelihood of gland blockage.

Objawy, na które należy zwrócić uwagę

1. Visible Lump on the Eyelid – The most obvious symptom of a meibomian gland tumor is a small bump or lump along the eyelid edge. This lump may grow outward or inward, impacting the eye’s surface if it becomes large.
2. Irritation and Redness – As the tumor grows, it may cause local irritation, leading to red, inflamed eyelids. This can make the area itchy or uncomfortable for your dog.
3. Excess Tearing and Tear Staining – Larger tumors may interfere with blinking, causing excessive tearing and tear staining around the eyes. This often results in a wet area below the eyes, which can attract dirt and cause further irritation.
4. Eye Discharge or Secondary Infections – In some cases, meibomian gland tumors may lead to infections or ulcers if they create friction with the eye surface, resulting in discharge or cloudiness in the eye.

How Are Meibomian Gland Tumors Diagnosed?

A veterinarian can usually diagnose meibomian gland tumors based on their appearance and location on the eyelid. If there’s any concern about malignancy, a biopsy may be performed to confirm the tumor’s nature. Early detection is key to ensuring the best outcome, as untreated tumors can lead to complications over time.

Opcje leczenia

1. Usuwanie chirurgiczne – For larger tumors causing discomfort or interference with the eye, surgical removal is often recommended. This simple procedure can prevent further irritation and discomfort, especially if the tumor impacts normal blinking.
2. Krioterapia – In some cases, cryotherapy is used to freeze and remove the tumor. This treatment is minimally invasive and effective for small tumors, particularly when surgery is not an ideal option for the dog’s age or health condition.

Aftercare and Prevention Tips

Post-treatment care is essential to ensure proper healing. Keeping the eye area clean and free from potential irritants can reduce the chances of regrowth. Additionally, routine check-ups with your vet allow for early detection of any new growths, ensuring they are managed before causing discomfort.

Meibomian gland tumors are common in dogs, especially as they age. While generally benign, they can cause discomfort if left untreated. With early detection and appropriate treatment, most meibomian gland tumors can be managed effectively, allowing your dog to maintain clear, healthy vision.
