Quick answer
What is Chalazion?
A chalazion is a painless lump that develops in the eyelid when one of the small oil glands (meibomian glands) becomes blocked and swells. It differs from a stye, which is usually a painful, red swelling at the eyelash base caused by infection; a chalazion is typically a firmer, painless lump a little further from the edge of the lid, and often develops after a stye or with a tendency to blocked glands (as in blepharitis or rosacea).
- How it is treated: Most chalazia clear up on their own over a few weeks to months, and simple home treatment speeds this and helps prevent recurrence.
- Self-care: Warm compresses and gentle eyelid massage, regular eyelid hygiene (especially with blepharitis or rosacea), and not squeezing the lump all help a chalazion clear and reduce recurrence.
- When to seek help: See a GP or optician if an eyelid lump is large, persistent despite warm compresses, keeps recurring in the same place, or affects your vision, so it can be assessed and treated if needed.
What it is
A chalazion is a painless lump that develops in the eyelid when one of the small oil glands (meibomian glands) becomes blocked and swells. It differs from a stye, which is usually a painful, red swelling at the eyelash base caused by infection; a chalazion is typically a firmer, painless lump a little further from the edge of the lid, and often develops after a stye or with a tendency to blocked glands (as in blepharitis or rosacea). It can range from small to large enough to press on the eye and, rarely, blur vision. Chalazia are common and harmless, though they can be a cosmetic nuisance and take weeks to resolve. Recurrent chalazia in the same spot occasionally prompt a check by an eye specialist.
How it is treated
Most chalazia clear up on their own over a few weeks to months, and simple home treatment speeds this and helps prevent recurrence. Warm compresses held against the closed eyelid for several minutes a few times a day soften the blocked oil and encourage it to drain, and gently massaging the lid afterwards can help. Good eyelid hygiene — cleaning the lid margins regularly — is useful, especially if there is underlying blepharitis. It is important not to squeeze or pick at a chalazion. If a chalazion is large, persistent, or bothersome despite these measures, a minor procedure to drain it, or sometimes a steroid injection, can be carried out by an eye specialist. Care is usually guided by a GP or optician first, with referral if needed.
