Chalazion
A chalazion is a painless nodule on the upper or lower eyelid caused by blockage of a Meibomian gland — the oil-secreting glands that line the inner edge of the eyelid. Most resolve with conservative measures; persistent ones are quickly and effectively treated in the office with a small drainage procedure.
What Is a Chalazion?
The eyelids contain 25–30 Meibomian glands in the upper lid and 20–25 in the lower lid. These glands open along the lid margin just behind the lash line and secrete a lipid-rich oil that forms the outermost layer of the tear film, slowing evaporation. When a gland duct becomes blocked — by thickened secretions, debris, or inflammation — oil backs up, the gland swells, and the oil spills into the surrounding eyelid tissue. The body mounts an inflammatory response to the trapped oil, forming a well-defined granuloma: the chalazion.
Unlike an acute infection, a chalazion is not tender and is not hot to the touch. It may appear as a painless lump on the eyelid, cause mild heaviness or blurring, or even indent the cornea and cause transient astigmatism if large. Most chalazia are in the upper eyelid, where the Meibomian glands are more numerous.
Causes & Risk Factors
Chalazia are more common in people with certain underlying conditions that affect the quality or quantity of Meibomian gland secretions:
Meibomian Gland Dysfunction (MGD)
The most common predisposing condition. Thickened or dysfunctional oil secretions clog ducts, predisposing to chalazia. Often overlaps with blepharitis.
Rosacea
Ocular rosacea is strongly associated with recurrent chalazia. The chronic lid inflammation alters gland secretion composition and promotes duct obstruction.
Seborrheic Dermatitis
Skin flaking and scaling contribute to lid margin debris that can block Meibomian gland openings.
Contact Lens Wear
Chronic contact lens use can alter lid anatomy and contribute to Meibomian gland dropout over time.
A chalazion developing in an older patient, recurring in the same location, or failing to respond to standard treatment should be sent for pathologic evaluation to exclude sebaceous gland carcinoma — a rare but important diagnosis that can mimic a chalazion.
Chalazion vs. Stye (Hordeolum)
| Feature | Chalazion | Stye (Hordeolum) |
|---|---|---|
| Cause | Meibomian gland blockage (inflammatory) | Bacterial infection (usually Staph. aureus) |
| Pain | Painless | Painful, tender |
| Location | Within eyelid tissue (not at lid margin) | At lid margin (external) or within tarsal gland (internal) |
| Acuity | Slow onset — days to weeks | Acute — often develops overnight |
| Treatment | Warm compresses; I&C if persistent | Warm compresses; topical antibiotics; oral if spreading |
| Resolution | Weeks to months; may need drainage | Usually 1–2 weeks with treatment |
Conservative Treatment
The majority of chalazia, especially small or early ones, respond to conservative measures. The cornerstone is warm compresses:
Warm Compress Technique
- Soak a clean washcloth in comfortably hot water (not scalding).
- Place over the closed eyelid for 10 minutes.
- Reheat as needed to maintain temperature throughout.
- After removing the compress, gently massage the eyelid in a rolling motion toward the lid margin.
- Repeat 3–4 times daily for at least 4–6 weeks.
Heated eye masks (e.g., Bruder mask, microwaved to 40–45°C) deliver more consistent heat than washcloths and are recommended for recurrent cases.
For very small chalazia or those showing inflammation, a single intralesional triamcinolone injection may accelerate resolution and avoid the need for incision. This is performed in the office with minimal discomfort after topical anesthetic drops and/or a small subcutaneous lidocaine injection.
Steroid injection is preferred for lesions in the central upper eyelid where a skin scar would be visible, for patients who want to avoid incision, and for early inflammatory stages before the chalazion has fully organized.
Surgical Drainage — Incision & Curettage (I&C)
Chalazia that persist beyond 4–6 weeks of conservative treatment, or those large enough to cause significant blurring, lid heaviness, or cosmetic concern, are effectively treated with incision and curettage — a minor in-office procedure.
The Procedure
- Topical anesthetic drops are placed in the eye. A small amount of local anesthetic (lidocaine with epinephrine) is injected into the eyelid — the only moment of any discomfort.
- A chalazion clamp is applied to the eyelid to control bleeding and evert the lid.
- A small vertical incision is made on the inner surface of the eyelid (palpebral conjunctiva) — no external skin incision, no visible scar.
- The contents of the chalazion (thickened oil and granulomatous tissue) are removed with a curette.
- The clamp is removed; the incision does not require suturing.
After the Procedure
- Antibiotic ointment is applied to the eye for 3–5 days.
- Mild bruising and swelling resolve over 1–2 weeks.
- The eye may feel scratchy for a few days while the internal incision heals.
- Return to normal activities the same day; no restrictions on driving after 2–3 hours.
- Success rate exceeds 90%. Recurrence in the same location should prompt pathologic evaluation.
Recurrent Chalazia
Patients with Meibomian gland dysfunction, rosacea, or seborrheic blepharitis tend to develop chalazia repeatedly. Long-term management focuses on treating the underlying lid disease:
- Daily lid hygiene
Warm compresses and lid scrubs (diluted baby shampoo or commercial lid wipes) reduce lid margin debris and help keep gland openings clear.
- Omega-3 fatty acids
Daily supplementation (1–2 g EPA/DHA) improves the quality of Meibomian gland secretions in patients with MGD.
- Oral doxycycline
Low-dose doxycycline (50–100 mg daily for 2–3 months) has anti-inflammatory effects on Meibomian glands, reducing recurrence in patients with rosacea or chronic blepharitis.
- Treating rosacea
Dermatologic management of rosacea — including topical metronidazole, azelaic acid, or oral antibiotics — often dramatically reduces chalazion frequency.
Important: A chalazion that recurs in the same eyelid location, is associated with lash loss, or does not resolve after drainage should be biopsied to exclude sebaceous gland carcinoma — a malignant tumor that can mimic a chalazion and is more common in older adults.
When to See a Specialist
Most chalazia can be initially managed by your optometrist or primary care provider. Referral to an oculoplastic surgeon is appropriate when:
- The chalazion has not resolved after 4–6 weeks of warm compresses.
- It is large enough to distort vision or cause corneal astigmatism.
- You have had 3 or more chalazia in the same location (rule out malignancy).
- The lesion is associated with loss of eyelashes (madarosis).
- You are a child — drainage requires cooperation or brief sedation and should be performed by an experienced surgeon.
- The chalazion has pointing to the skin surface and requires external incision.
- You prefer a specialist with specific expertise in eyelid procedures.
