Chalazion in Dogs Dog Eyelid Cyst | by AADG, DVM

In this article originally written for Honest Paws, Dr. Gaffud explains chalazion in dogs (an eyelid cyst of the meibomian gland), how it develops, how vets diagnose it, and the treatment or management options available.

Key Takeaways

• What is a chalazion? Chalazion in dogs is a benign, non-tumorous swelling or cyst in the eyelid, caused by blockage of a meibomian (oil) gland.

  
  

• Pathogenesis & risk factors: When the duct of a meibomian gland becomes blocked, its oily secretions build up, leading to a granulomatous reaction and cyst formation. Underlying inflammation (blepharitis), eyelid conformational issues, or chronic ocular irritation can predispose to blockage. Some breeds (especially brachycephalic or dogs with prominent eyes) may be more prone to eyelid gland dysfunction.

  
  

• Clinical signs / symptoms: The typical presentation is a firm, painless lump on the eyelid margin or inside the eyelid. Nearby swelling, redness, tearing, mild irritation, or eye rubbing may occur, especially if secondary inflammation or infection develops. In more advanced cases, the lesion may protrude visibly or even affect eyelid function or corneal contact.

  
  

• Diagnosis: A veterinary ophthalmic exam is key: assessing eyelid margins, gland structures, and ruling out other eyelid masses. Ancillary tests may include cytology or fine-needle aspirate / punch biopsy to rule out more aggressive lesions, especially if the mass is atypical or persistent. Ophthalmic tests (e.g. fluorescein, tear tests) help rule out corneal damage or concurrent eye disease.

  
  

• Treatment & management: Mild, asymptomatic chalazia may resolve with conservative therapy: warm compresses, gentle eyelid massage, cleaning of eyelid margins. Topical anti-inflammatory or antibiotic ointments may be used if secondary irritation or infection is present. In persistent, large, or interfering lesions, surgical intervention (incision/drainage, excision, curettage) is recommended. Adjunctive cryotherapy (freezing) is sometimes used to reduce recurrence by treating residual gland tissue.

  
  

• Prognosis & recurrence: Most chalazia have a good prognosis when treated appropriately; recurrence may occur if underlying gland or eyelid factors are not addressed. Untreated lesions may lead to chronic irritation, secondary infection, or eyelid misalignment / corneal complications.
