## Quick answer

A chalazion (meibomian cyst) is a benign, usually painless lump in the eyelid caused by obstruction of a meibomian oil gland. Unlike a stye, which is an acute infection, it tends to enlarge slowly. Most chalazia resolve with conservative treatment, but larger or persistent ones may need minor surgery.

## Overview

A chalazion is a benign, localised swelling within the eyelid caused by obstruction of a meibomian gland — one of many small oil-secreting glands that line the upper and lower lid margins. Unlike a stye (hordeolum), which is an acute infection, a chalazion is typically a painless, slowly enlarging lump. Most chalazia resolve with conservative treatment, but larger or persistent ones require minor surgery.

## Treatment

Warm compresses applied for 10 minutes twice daily, combined with lid massage, resolve many early chalazia. If the cyst persists beyond 4–6 weeks or is causing visual symptoms, incision and curettage under local anaesthetic provides rapid and definitive resolution.

## FAQs

### How long does a chalazion take to go away?

Many clear within a few weeks with warm compresses, but some take longer. A lump that persists may need to be assessed by a clinician.

### Should I squeeze a chalazion?

No. Squeezing can cause damage or infection. Use warm compresses and gentle massage instead, and seek advice if it does not settle.

### What is the difference between a chalazion and a stye?

A chalazion is a benign, typically painless lump caused by obstruction of a meibomian oil gland, and it usually enlarges slowly. A stye (hordeolum) is an acute infection. While a chalazion can become red and tender if secondary infection develops, it is not primarily an infective swelling.

### How can I treat a chalazion at home?

Many early chalazia resolve with conservative care: warm compresses applied for 10 minutes twice daily, combined with lid massage. This helps clear the blocked meibomian gland. If the lump persists beyond four to six weeks or affects vision, a minor surgical procedure may be needed for definitive resolution.

### When does a chalazion need surgery?

Surgery is considered if a chalazion persists beyond four to six weeks despite warm compresses and lid massage, or if it is large enough to cause visual symptoms by pressing on the cornea. Incision and curettage under local anaesthetic provides rapid and definitive resolution of the cyst.
