What Is a Chalazion?
A chalazion is a painless or mildly tender lump that develops on the eyelid due to blockage and inflammation of an oil (meibomian) gland. Unlike a stye, a chalazion is not usually caused by infection and often develops more slowly.
Chalazia are common in both adults and children and are usually harmless, though they can occasionally affect vision if large.
What Causes a Chalazion?
Chalazia are caused by:
- Blocked oil glands in the eyelid
- Inflammation rather than infection
- Underlying eyelid conditions such as blepharitis
- Skin conditions like rosacea or seborrhoeic dermatitis
What Are the Common Symptoms of a Chalazion?
You may notice:
- A firm, round lump on the eyelid
- Usually painless or only mildly tender
- Swelling of part of the eyelid
- Cosmetic concern
- Blurred vision if the chalazion is large and presses on the eye
How Is a Chalazion Diagnosed?
Diagnosis is usually based on:
- Appearance and location of the eyelid lump
- Lack of redness or pain compared to a stye
Online GP consultations can help differentiate a chalazion from other eyelid lumps. In-person review may be required if the diagnosis is uncertain or the lump persists.
How Long Does a Chalazion Last?
- Many chalazia resolve on their own within weeks to months
- Some may persist for several months without treatment
- Regular warm compresses can speed resolution
Is a Chalazion Contagious?
No. A chalazion is not contagious and cannot be passed from person to person.
