Understand symptoms, causes, and prevention of chalazion with expert eye care at ASG Eye Hospital.
A chalazion is a cyst-like swelling formed when the oil-producing meibomian gland in the eyelid becomes blocked. The trapped oil causes inflammation and forms a firm lump inside the eyelid. Chalazion is often confused with a stye, but unlike a stye, it is usually not caused by an active bacterial infection and is often less painful.
Small chalazia may resolve on their own, while larger or persistent chalazia may require medical treatment or surgical removal.
A chalazion is a painless or mildly painful lump that develops on the eyelid due to blockage of the meibomian (oil) glands. It commonly appears as a small swelling on the upper or lower eyelid and may gradually increase in size over time. Although a chalazion is usually non-infectious, untreated cases can cause eyelid discomfort, blurred vision, cosmetic concerns, and recurrent inflammation. At ASG Eye Hospital, experienced eye specialists provide advanced diagnosis and treatment for chalazion using medical and minimally invasive surgical techniques.
Common symptoms of chalazion include:
In some cases, a chalazion may become inflamed and painful if secondary infection develops.
Chalazion develops when the oil glands in the eyelid become blocked. Common causes and contributing factors include:
Maintaining proper eyelid hygiene can help reduce the risk of recurring chalazion.
People with the following conditions may have a higher risk of developing chalazion:
Although chalazion and stye both affect the eyelids, they are different conditions.
| Feature | Chalazion | Stye |
|---|---|---|
| Cause | Blocked oil gland | Bacterial infection |
| Pain | Usually mild or painless | Often painful |
| Growth | Slow development | Sudden swelling |
| Infection | Usually non-infectious | Infectious |
| Location | Inside eyelid | Near eyelash root |
Proper diagnosis by an eye specialist is important because persistent eyelid lumps may sometimes resemble other eyelid conditions.
If left untreated, chalazion may lead to:
Large chalazia affecting vision may require prompt medical attention.
At ASG Eye Hospital, eye specialists perform a detailed eyelid examination to diagnose chalazion and rule out other eyelid conditions. Evaluation may include:
Persistent or recurrent chalazia may require further evaluation to rule out underlying eyelid disease.
Warm compresses are commonly recommended to soften blocked oil secretions and help the chalazion drain naturally. Patients are usually advised to apply warm compresses several times daily.
Gentle eyelid cleaning and massage help improve gland function and reduce recurrence risk. Maintaining proper eyelid hygiene is essential for long-term prevention.
Anti-inflammatory medicines, antibiotic ointments, or eye drops may be prescribed if inflammation or infection is present.
In selected cases, steroid injections may help reduce inflammation and shrink the chalazion without surgery.
Persistent, large, or recurrent chalazia may require minor surgical removal. The procedure involves draining the blocked gland through a small incision and is usually performed as a day-care procedure under local anesthesia.
Recovery after chalazion removal is usually quick and may include:
Most patients resume routine activities within a short period after the procedure.
You can reduce the risk of chalazion by:
