What is a Chalazion? Causes, Symptoms, and Treatment

Posted April 24, 2025

If you’ve noticed a lump or swelling on your eyelid, you may be wondering, what is a chalazion? A chalazion is a common eyelid condition that can cause discomfort and affect your appearance. While it often resolves on its own, persistent or severe cases may require professional intervention. At Blue Fin Vision® Eye Clinic, with locations in London, Chelmsford, and Hatfield, we specialise in advanced chalazion treatments, including chalazion removal surgery, to restore the health and comfort of your eyelids.

What is a Chalazion?

A chalazion is a small, painless lump that forms on the eyelid due to the blockage of a meibomian gland. These glands are responsible for producing oil that lubricates the eye. When the gland becomes clogged, the trapped oil can lead to swelling and inflammation, resulting in what is known as a meibomian gland chalazion or chalazion meibomian cyst.

Unlike styes, which are caused by bacterial infections, chalazia are non-infectious and typically develop further from the edge of the eyelid.

Chalazion Causes

Several factors can contribute to the formation of a chalazion:

Blocked meibomian glands: The most common cause, often linked to poor eyelid hygiene or excessive oil production.
Chronic blepharitis: Inflammation of the eyelid margins increases the risk of gland blockage.
Skin conditions: Conditions like rosacea or seborrheic dermatitis can affect oil gland function.
Previous styes: Recurrent styes can lead to blocked glands and subsequent chalazia.
Other medical conditions: Diabetes and hormonal changes may predispose individuals to chalazia.

Chalazion Symptoms

The symptoms of a chalazion vary depending on its size and severity:

A lump or swelling on the upper or lower eyelid
Mild tenderness or discomfort
Redness around the affected area
Blurred vision if the lump presses against the eye
Eyelid heaviness or drooping

In some cases, a chalazion may become large enough to cause noticeable eyelid hooding, obstructing vision and requiring treatment.

Chalazion Treatments

Most chalazia resolve naturally within weeks to months with simple home care measures. However, persistent or severe cases may require professional chalazion treatment. Below are common options for managing chalazia:

Home Remedies

Warm compresses: Applying a warm compress several times a day helps soften the blockage and promote drainage.
Gentle massage: Massaging the eyelid can encourage gland function and reduce swelling.
Eyelid hygiene: Regular cleaning with mild soap or specialised eyelid wipes prevents further blockages.

Medical Treatments

If home remedies fail to resolve the chalazion, medical intervention may be necessary:

Steroid injections: Corticosteroids can reduce inflammation and speed up healing in stubborn cases.
Antibiotic ointments: Used if secondary infection is suspected, although chalazia are typically non-infectious.

Chalazion Surgery

For large or long-lasting chalazia that do not respond to other treatments, surgery may be required:

Chalazion removal surgery involves draining or excising the cyst through a small incision on the inner side of the eyelid. This minimally invasive procedure is performed under local anaesthetic and offers quick recovery times.
At Blue Fin Vision®, our experienced oculoplastic surgeons use precise techniques to ensure effective removal while minimising scarring and discomfort.
