A small lump on the eyelid can be concerning—especially if it does not resolve on its own. Two common causes are chalazia (plural of chalazion) and other eyelid cysts. While generally harmless, these lumps can cause discomfort, interfere with vision, or lead to cosmetic concerns. With proper diagnosis and timely treatment, most chalazia and eyelid cysts can be resolved quickly and effectively. This guide explains what they are, why they occur, how they can be treated, and when it is important to seek professional care.
What is a Chalazion?
A chalazion is a benign (non-cancerous) lump that develops in the eyelid when a meibomian gland—an oil-producing gland along the eyelid margin—becomes blocked.
- Difference from a stye: A stye (hordeolum) is usually caused by a bacterial infection and tends to be painful and red. A chalazion is more likely to be painless and develops gradually over days or weeks.
- Appearance: Usually a firm, round swelling in the upper or lower eyelid, sometimes with mild redness.
What are eyelid cysts?
The term “eyelid cyst” is often used loosely for any lump on the eyelid. It can include:
- Chalazia – from blocked oil glands.
- Sebaceous cysts – from blocked skin glands.
- Inclusion cysts – from trapped skin cells.
- Sweat gland cysts – from blocked sweat glands.
Accurate diagnosis is important because, in rare cases, an eyelid lump can be a skin cancer masquerading as a cyst.
Types of chalazia and Eyelid cysts
There are several types of eyelid lumps, each developing from different glands or tissues. Understanding the differences helps in choosing the right course of treatment:
1. Internal chalazion
- Develops deeper inside the eyelid.
- Caused by blockage of the meibomian (oil) glands.
- Usually larger and may press on the eye, causing blurred vision.
2. External chalazion
- Forms closer to the eyelid surface.
- Often smaller and easier to notice early.
- May follow a history of a stye.
3. Sebaceous cyst
- Forms when a skin (sebaceous) gland gets blocked.
- Appears as a smooth, round, often slow-growing lump.
- Does not typically cause pain.
4. Epidermal Inclusion cyst
- Caused by trapped skin cells under the surface.
- Feels like a small, firm pearl-like bump.
- Can enlarge over time if not treated.
5. Sweat gland cyst (Hydrocystoma)
- Occurs when sweat glands of the eyelid become clogged.
- Appears as a clear, fluid-filled bump.
- More common in hot and humid climates.
6. Stye (Hordeolum) – Often confused with chalazion
- A painful, red, infected bump near the lashes.
- Usually contains pus.
- Can turn into a chalazion if the infection settles but the gland remains blocked.
Symptoms to look out for
While chalazia and eyelid cysts often cause no pain, symptoms can include:
- A lump in the eyelid – may be small or grow over weeks.
- Mild swelling of the eyelid.
- Tenderness (more common early on).
- Redness of the skin over the lump.
- Watery eyes if the lump irritates the eye surface.
- Blurred vision if the lump presses on the cornea.
- Heavy eyelid feeling.
If you have severe pain, rapid swelling, fever, or vision changes—seek prompt medical attention.
Stages of chalazion development
Chalazia typically develop gradually. Recognising the stages helps you understand when home care is enough and when medical support is needed.
Stage 1: Early inflammation (Day 1–3)
- Mild discomfort or eyelid tenderness.
- Slightly red, swollen patch on the eyelid.
- Feels like a small internal “pinpoint” irritation.
Stage 2: Lump formation (Day 3–7)
- A firm, round lump begins to form.
- Swelling becomes more noticeable.
- Usually no pain at this stage.
- Vision may blur slightly if the lump presses on the cornea.
Stage 3: Mature chalazion (Week 1–4)
- Lump becomes well-defined, painless, and stable in size.
- Skin may look stretched or slightly swollen.
- Home treatments like warm compresses may reduce size gradually.
Stage 4: Chronic or Persistent chalazion (After 4+ weeks)
- Lump becomes firm or rubbery.
- Less responsive to warm compresses.
- May require medical intervention—such as a steroid injection or drainage procedure.
Stage 5: Possible complications (Rare)
- Secondary infection (turns into a painful stye).
- Significant pressure on the cornea causing blurred vision.
- Recurrence in the same spot.
- Suspicious features that could mimic eyelid cancer (requires ophthalmologist review).
Causes and risk factors
Chalazia occur when the oily secretions from the meibomian glands cannot drain normally, causing the gland to swell. Reasons include:
- Chronic blepharitis – ongoing eyelid margin inflammation.
- Rosacea – a skin condition affecting oil glands.
- Seborrheic dermatitis – oily, flaky skin.
- History of styes or chalazia – some people are more prone.
- Poor eyelid hygiene – buildup of oil, bacteria, or debris.
- Systemic conditions – like diabetes, which may affect healing.
- Environmental factors – dust, pollution, or heavy makeup use.
Diagnosis by an eyecare professional
In most cases, a careful clinical examination is required. This is inclusive of assessing :
- The size and location of the lump.
- Any signs of infection or inflammation.
- Whether there are multiple lumps or recurrence.
- If there are features suspicious for malignancy. (unusual shape, bleeding, lash loss)
If there is concern about cancer, a biopsy may be recommended.
Treatment options
1. Self-care and home treatment
- Warm compresses: Apply a clean, warm cloth to the closed eyelid for 10–15 minutes, 3–4 times daily. There are commercially available eyelid masks as well. This softens the blockage and encourages drainage.
- Gentle massage: After warming, gently massage the lump towards the lash line to help clear the gland.
- Eyelid hygiene: Use diluted baby shampoo or commercially available eyelid wipes to keep the area clean.
Many chalazia resolve within a few weeks with these measures.
2. Medical treatment
If self-care does not help or if the cyst is inflamed and/or painful:
- Antibiotic eye drops or ointment – if there is secondary infection.
- Anti-inflammatory medication – to reduce swelling and discomfort.
- Steroid injection – in some cases, to shrink persistent lumps.
3. Surgical treatment
For large, long-standing, or vision-affecting chalazia:
- A minor surgical procedure can be done under local anaesthesia to drain the contents.
- The procedure is quick (usually under 15 minutes) and recovery is rapid.
- Post-operative care includes antibiotic ointment and warm compresses to prevent recurrence.
Preventing recurrence
You can reduce the risk of getting chalazia or eyelid cysts by:
- Practising regular eyelid hygiene.
- Managing blepharitis or rosacea under medical guidance.
- Removing eye makeup thoroughly each night.
- Avoiding rubbing eyes with unwashed hands.
When to seek specialist care?
Make an appointment with an ophthalmologist if:
- The lump persists beyond 8-12 weeks despite home care.
- There is rapid growth or recurrent swelling in the same spot.
- You develop vision changes.
- The lump bleeds or has an irregular appearance.
- You have multiple lumps at the same time.
Conclusion
Chalazia and eyelid cysts are common, and while they are usually harmless, they can be uncomfortable and cosmetically bothersome. With proper diagnosis and timely treatment—whether through self-care, medication, or a minor procedure—most patients make a full recovery.

FAQs
Makeup and contact lenses themselves do not directly cause chalazia, but poor hygiene—such as not removing makeup completely or wearing unclean contact lenses—can increase the risk by introducing bacteria or blocking oil glands.
No, they are not contagious. You can not spread them to others, but the underlying conditions that cause them—like blepharitis—can recur in the same person.
Some resolve on their own within 2–8 weeks, but persistent or large lumps may need medical intervention.
Yes, children can develop them, especially if they have poor eyelid hygiene or underlying skin conditions. Warm compresses and gentle cleaning are safe first steps.
A healthy diet rich in omega-3 fatty acids (like fish, flaxseed, and walnuts) may help maintain healthy oil gland function and reduce the risk in people prone to eyelid inflammation.
No, squeezing can worsen inflammation, cause infection, and even damage the eyelid. Always let a specialist manage drainage if needed.
Stress and fatigue do not directly cause cysts, but they can weaken your immune system, making it harder for your body to control eyelid inflammation.
