What is chalazion?
A chalazion is a small lump, or cyst, that develops slowly in the eyelid. It can sometimes look alarming, but it’s usually painless and rarely requires treatment. It typically occurs when a meibomian gland, which produces the oil that helps lubricate the eyes, becomes blocked.
This blockage leads to the accumulation of oil in the gland, causing inflammation and the formation of a firm, painless bump on the eyelid.

What causes chalazion?
A chalazion is typically caused by a blockage in one of the small oil-producing glands (meibomian glands) located within the eyelids. These glands secrete an oily substance that contributes to the composition of tears and helps prevent evaporation of the tear film. When a meibomian gland becomes blocked, the oil cannot flow out properly, leading to the accumulation of oil within the gland and the formation of a chalazion.
Several factors can contribute to the development of a chalazion:
Meibomian Gland Dysfunction (MGD):
MGD is a common condition where the meibomian glands do not function correctly. Changes in the quality or quantity of the gland's secretions can lead to blockages.
Bacterial Infection:
In some cases, a chalazion can occur as a result of a secondary bacterial infection of an oil gland. This can lead to increased inflammation and the formation of a lump.
Chronic Blepharitis:
Blepharitis is inflammation of the eyelids, and chronic cases may contribute to the development of chalazion. Inflammation and debris along the eyelid margin can affect the normal functioning of the meibomian glands.
Poor Eyelid Hygiene:
Insufficient eyelid hygiene, which includes not cleaning the eyelids properly, can contribute to the accumulation of debris and blockages in the meibomian glands.
Rosace:
Individuals with rosacea, a skin condition characterized by redness and visible blood vessels, may be more prone to developing meibomian gland dysfunction and chalazia.
Hormonal Changes:
Changes in hormonal levels, especially during puberty or menopause, can influence the function of the meibomian glands and contribute to blockages.
Use of Contact Lenses:
Some studies suggest that the use of contact lenses may be associated with an increased risk of developing chalazia.
It's important to note that while bacterial infections can contribute to the development of a chalazion, a chalazion itself is not typically an infectious condition. Chalazia are usually sterile and do not result from direct contagion.

Chalazion symptoms
Common symptoms of include:
- Lump on the Eyelid: The most noticeable symptom is a small, round lump or swelling on the eyelid. It can be tender to the touch
- Eyelid Swelling: The affected eyelid may appear swollen or puffy
- Redness: There might be redness around the lump, especially if it's irritated or infected
- Blurry Vision: In some cases, if the chalazion is large enough and presses on the eye, it might cause blurry vision
- Tearing: Excessive tearing or watering of the eye might occur, particularly if the chalazion is irritating the eye
- Discomfort: While chalazia are typically painless, they can cause discomfort due to their presence on the eyelid or if they become infected
Treatment for chalazion
Warm Compresses
Applying warm compresses to the affected eyelid can help soften the oil in the blocked gland, promoting drainage and reducing inflammation.
Eyelid Massage
Gently massaging the eyelid may aid in the drainage of the blocked gland.
Maintain Lid Hygiene
Keeping the eyelids clean is important to prevent further blockages. This can be achieved through gentle cleaning with a mild, non-irritating cleanser.
Prescription Medications
In some cases, a healthcare professional may prescribe antibiotic ointments or steroid injections to reduce inflammation.
Surgical Drainage
If conservative measures are ineffective, a healthcare provider may perform a minor surgical procedure to drain the chalazion.
It's crucial to consult with your trusted Spec-Savers Optometrist if you suspect you have a chalazion or any other eye condition. They can provide a proper diagnosis and recommend an appropriate course of treatment based on the severity and individual characteristics of the condition.
