Eyelid lumps: chalazion and stye

A chalazion is a firm lump from a blocked oil gland in the eyelid. A stye is an infected gland near the lashes, more like a small boil. Both are common in children and adults, and many settle with warm compresses.

IN SHORT

They look alike but are not the same. A stye is usually red and sore, sometimes with a white head at the lash line. A chalazion is usually a firmer, less painful lump inside the lid. Warm compresses are the first step for both. A lump that doesn't settle can be drained in the clinic, and in young children a larger lump on the upper lid can change the shape of the eye, so it is worth a check.

KEY FACTS
What it isChalazion: a blocked oil gland. Stye: an infected gland near the lashes
Who gets itChildren and adults, more often with blepharitis, eye rubbing, rosacea or around puberty
What you might noticeA lump on the lid, redness, swelling or tenderness; a stye may have a white head
How it is treatedWarm compresses first. A lump that lasts can be drained in the clinic
When to bookIf a lump lasts more than a few weeks, keeps coming back, or a child's upper-lid lump is large. Same day if swelling spreads or vision changes
HOW TO TELL

Chalazion or stye?

  • Stye: red, sore bump at the edge of the lid, sometimes with a white head
  • Chalazion: firmer lump further into the lid, often not painful
  • Both: some swelling and redness around the lump
  • Don't squeeze either one
Warm compressesA clean, warm (not hot) cloth held on the closed lid for a few minutes, several times a day. Advice on timing varies, so ask us.

HOW WE CHECK

At the appointment

Adults and children are both seen for lid lumps.

  1. 1A close look under the microscope. To tell a chalazion from a stye, and check the lid edges for blepharitis.
  2. 2Vision and prescription. In children, a larger upper-lid lump can cause astigmatism.
  3. 3A plan. Compresses, lid hygiene, or treatment in the chair if it has lasted.
TREATMENT

From compresses to a quick procedure

Most settle with simple care. A lump that hangs around can be drained in the chair.

FIRST STEP

Warm compresses

For both. Don't squeeze. Keep lids clean, especially if blepharitis is a factor.

IN THE CLINIC

Drainage in the chair

For a chalazion, or a stye that hasn't settled: numbing, then a small drainage from the inside of the lid. It depends on how still a child can stay, and is usually easier from around age 10.

REFERRAL

Steroid injection

Another option for a chalazion, done by an eye surgeon.

What studies show: in one trial, about 9 in 10 chalazia had gone within three weeks after drainage or a steroid injection, compared with about half with warm compresses alone.

WHEN TO SEE US

Book a check, or get help today

Book an eye test if

  • A lump has lasted more than a few weeks
  • Lumps keep coming back, especially in the same spot
  • Your child has a lump on the upper lid
  • Your eyelids are often red, crusty or itchy

Get help the same day if

  • Swelling spreads across the eyelid or around the eye
  • The eye bulges, eye movements hurt, or vision changes
  • Your child has a fever or seems unwell

These can be signs of a spreading infection. Go to your nearest emergency department, or call us on (03) 9404 5279 in clinic hours.

GOOD TO KNOW

Questions parents ask

Are a chalazion and a stye the same thing?

No. A stye is an infected gland; a chalazion is a blocked one. They are treated a little differently.

Do I need antibiotics?

Usually not. A chalazion isn't an infection. A stye usually settles with compresses; see us if redness spreads.

Why does my child keep getting them?

Blepharitis, eye rubbing, rosacea and puberty make them more likely. Daily lid hygiene helps.

Can a chalazion affect vision?

In young children, a larger lump on the upper lid can change the shape of the eye and cause astigmatism, so it is worth a check.

How long do they take to go?

Often days to weeks. Some take longer, and sources differ on how long.
