Understanding Chalazion

A stye (hordeolum) is a bacterial infection — it comes on fast, is painful, red, and warm, and usually sits right at the lash line. A chalazion is a blocked oil gland — it comes on gradually, is firm and largely painless, and sits further back in the lid. Styes can evolve into chalazia if they don’t fully resolve, which is why getting them looked at early matters.

With consistent warm compresses and proper lid hygiene, most small chalazia soften within one to two weeks and fully resolve over four to six weeks. Without treatment, they can linger for two to three months or longer, and they’re more likely to return. Larger chalazia, or ones that have been present for more than a month, usually need help — whether that’s in-clinic gland treatment, steroid injection, or occasionally surgical drainage.

What often gets missed is that even “self-resolving” chalazia tend to recur if the underlying meibomian gland dysfunction isn’t addressed — which is the whole reason we focus on treating the gland environment, not just the lump. An assessment is worth doing even for a single episode.

No — please don’t. A chalazion isn’t a pimple. The trapped oil is encapsulated in delicate lid tissue, and squeezing risks spreading inflammation, bruising the lid, introducing bacteria, or damaging nearby glands and lashes. Warm compresses soften the contents from the outside and let the gland drain naturally — that’s the safe way to help it along.

In most cases, recurring chalazia point to ongoing meibomian gland dysfunction or blepharitis that needs proper treatment — not anything sinister. The red flags that do warrant a closer look, and occasionally a biopsy, are: recurrence in the exact same location, an unusual or distorted appearance, failure to respond to standard treatment, localised loss of eyelashes in that spot, or new onset in a patient over 50. These features can sometimes suggest a rare condition called sebaceous cell carcinoma, which can mimic a chalazion and is treatable when caught early. It’s uncommon — but it’s the reason we take recurrent same-site chalazia seriously rather than simply draining them again. If you’ve been through this pattern, we’d much rather take a careful look than assume.

Surgical drainage (incision and curettage) is considered when a chalazion is large, persistent beyond several weeks of proper conservative treatment, pressing on the cornea and distorting vision, or cosmetically problematic. A steroid injection is sometimes used first as a less invasive alternative. Both procedures are performed by our oculoplastic colleagues at Uptown Eye Specialists, with UDEI managing the before-and-after medical care to reduce the chance of recurrence.

Initial assessment and surgical procedures such as incision and curettage are typically covered by OHIP when medically indicated. In-clinic treatments for meibomian gland disease — including UltraView DEL™ IPL, gland expression, and ZoHx — are specialised services not covered by OHIP. We provide itemised receipts for insurance claims.

No — a chalazion is not contagious. It’s a blocked oil gland, not an infection, so it cannot spread to family members, partners, or children through normal contact, shared towels, or sharing a pillow. If more than one person in your household develops chalazia, it’s usually because you share underlying risk factors like rosacea or blepharitis — not because one gave it to the other.

Because a chalazion is a mechanical blockage rather than an infection, antibiotic drops alone don’t resolve it. We do sometimes prescribe topical antibiotic or combined antibiotic-steroid drops when blepharitis or a secondary skin infection is present, and oral antibiotics can play a role in prevention for recurrent cases (see the prevention section above). But the foundation of chalazion care is warm compresses, lid hygiene, and treating the underlying meibomian gland disease — not drops.

Yes — chalazia occur in children, though they’re more common in adults. Kids who get them tend to have contributing factors like eczema, rosacea in the family, or subtle blepharitis. Treatment is the same gentle approach: warm compresses (parent-supervised for younger children), soft lid cleansing, and patience. Most resolve without any intervention. For large, persistent, or repeatedly recurring chalazia in children, referral to a paediatric oculoplastic specialist may be warranted — general anaesthesia is sometimes needed for very young children who can’t tolerate an awake procedure. We’re happy to assess and coordinate care as needed.

We welcome referrals for recurrent chalazia, chalazia that haven’t responded to conservative care, patients who may benefit from IPL-based gland therapy, or second opinions on whether a surgical procedure is warranted. Fax referrals to 416-292-0331, or contact our referral desk at 416-292-0334 or info@udei.ca. We’ll provide a consult letter back to you within one week of the patient’s visit.
