Chalazion: Symptoms, Causes, and Treatment

What Is a Chalazion?

A chalazion is a small red bump that forms on the eyelid, sometimes referred to as an eyelid cyst or meibomian cyst. It develops slowly when an oil gland in the eyelid, known as the meibomian gland, becomes blocked. Initially, a chalazion may cause pain, but this usually subsides as it progresses. Chalazia are most commonly found on the underside of the upper eyelid but can also appear on the lower lid.

Chalazia are more frequent in adults between ages 30 and 50, and although rare, they can also occur in children.

Chalazion vs. Stye: What’s the Difference?

It can be difficult to distinguish between a chalazion and a stye. Both result from blocked oil glands, but styes are bacterial infections that cause painful swelling near the edge of the eyelid. In contrast, chalazia develop further back on the eyelid and are usually not painful. Sometimes, a stye may evolve into a chalazion.

Symptoms of a Chalazion

The primary symptom of a chalazion is a noticeable bump on the eyelid. Additional symptoms may include:

• Redness, swelling, and mild tenderness in the eyelid

• Watery eyes due to irritation

• Blurred vision if the bump grows large enough to press against the cornea

• Swelling of the entire eyelid in more severe cases

Causes of a Chalazion

A chalazion forms when a meibomian gland becomes blocked, preventing oil from draining properly. This trapped oil leads to swelling and irritation in the surrounding tissue, resulting in a hard lump on the eyelid.

Risk Factors

You may be more prone to developing chalazia if you:

• Have had chalazia in the past

• Suffer from chronic blepharitis (inflammation of the eyelids)

• Have skin conditions such as rosacea or seborrheic dermatitis

• Experience hormonal changes

• Have oily or dry skin problems

Are Chalazia Contagious?

Unlike styes, chalazia are not contagious, as they are not caused by bacteria and cannot spread from one person to another.

Possible Complications

While most chalazia are harmless, large ones may press against the cornea, potentially leading to blurred or reduced vision.

Diagnosis

An eye care specialist such as an optometrist or ophthalmologist can diagnose a chalazion by:

• Reviewing your medical history

• Performing a comprehensive eye exam

• Using light and magnification to examine your eyelid glands closely

Treatment for Chalazion

Home Remedies

Most chalazia resolve on their own within a few weeks. At-home treatments include:

• Warm compresses: Apply a warm, damp cloth to the eyelid for 10–15 minutes, 3–4 times daily. This helps open the blocked gland.

• Good hygiene: Avoid wearing eye makeup, and keep the eyelid area clean.

Important: Never squeeze or attempt to pop a chalazion, as this may lead to infection.

Medical Treatments

If the chalazion does not improve with home care, an eye specialist may recommend:

• Drainage through a small incision

• Steroid injections to reduce inflammation

How Long Does a Chalazion Last?

With proper self-care, a chalazion may heal within one to two weeks. If left untreated, it can persist for four to six weeks or longer. Some may even last for several months.

Can Chalazia Be Prevented?

Yes, practicing good eye hygiene can lower your risk:

• Wash your hands before touching your eyes or contact lenses

• Clean and disinfect contact lenses properly

• Remove makeup before sleeping and replace mascara or eyeliner every 2–3 months

• Wash your face and eyelids regularly, especially if prone to blepharitis

Living With Chalazion

Seek medical care if your chalazion:

• Does not heal with home treatment

• Recurs frequently

• Causes vision problems

Questions to Ask Your Eye Care Provider

• How long will it take for the chalazion to heal?

• What treatment do you recommend if it doesn’t improve?

• How can I prevent future chalazia?

Outlook

A chalazion is generally a harmless and treatable condition. Most cases resolve naturally with warm compresses and good hygiene practices. Persistent or recurring chalazia can be effectively treated by an eye care specialist.
