A chalazion is a cyst in an eyelid.
A more technical and detailed definition of a chalazion is "a lesion of lipogranulomatous inflammation centered on a dysfunctional meibomian gland".
This may be explained simply in terms of inflammation due to blockage of the duct of a gland in the eyelid. That is, a chalazion is the result of a swollen sebaceous gland in the eyelid, caused by chronic (long-term, peristent) inflammation following blockage of the gland's duct.
A possible root cause of a chalazion is incomplete removal of eye-makeup, causing the oil from the cosmetic product(s) to gather in the glands. This condition is also relatively common in patients with posterior blepharitis.
- Topical antibiotic eye drops or ointment may be used for the initial acute infection.
- Surgical incision and curettage of the gland may be appropriate in some cases.
- Sometimes spontaneous resolution may occur, especially if the chalazion is small.
Potential complications (if untreated):
