The term chalazion (pronounced kah-la'-ze-on) comes from the Greek word meaning a small lump. It refers to a swelling in the eyelid caused by chronic inflammation of one of the small oil producing glands (meibomian glands) located in the upper and lower eyelids.
A chalazion is sometimes confused with a stye which also appears as a lump in the eyelid. A stye is an acute inflammatory infection of a lash follicle and forms a red sore lump near the edge of the eyelid. A chalazion is usually a reaction to trapped oil secretions and not caused by bacteria, although the site can become secondarily infected by bacteria. Chalazions tend to occur farther from the edge of the eyelid than styes (although a gradual swelling can be felt near the edge of the lid), and tend to "point" toward the inside or nose side of the eyelid. Occasionally, a chalazion can cause the entire eyelid to swell suddenly.
If there is pain on the bump in your lid then there is infection. Where there is pain there is infection. A chalazion does not have pain associated with it. Patients with Blepharitis tend to have more styes and Chalazions. Manage the Blepharitis and there will be less recurrence.
How is a Chalazion Treated?
When a chalazion is small and without symptoms, it may resolve without treatment. Usually, they don't resolve without treatment. If the chalazion is large, it may cause blurred vision by distorting the shape of the cornea.
Chalazions may be treated with any one of the following methods:
1) Antibiotics and/or steroid drops or injections;
2) Warm compresses;
Warm compresses can be applied in a variety of ways, The simplest method is to hold a clean washcloth, soaked in hot water, against the closed lid for five to ten minutes, three to four times a day. Repeatedly soak the washcloth in hot water to maintain adequate heat.
3) Massaging the affected area can lead to expression of the trapped oil secreations in the meibomian glands;
4) Surgical incision or excision
Chalazions usually respond well to treatment, although some people are prone to recurrences and may require continued treatment. If a chalazion reoccurs in the same place, your eye doctor may suggest a biopsy of the lesion to rule out more serious conditions.
