CHALAZION
What is Chalazion?
A chalazion is a cyst within the Meibomian gland (specialist oil glands) in the eyelid. These occur when the opening of a gland on the eyelid margin becomes blocked and the secretions are retained in a palpable, round, firm lump.
What causes Chalazion?
Blepharitis is a common cause for gland blockage and the same lid hygiene and hot compresses used to treat blepharitis are recommended to prevent and treat chalazia and avoid the need for surgical intervention.
Occasionally a chalazion can leak its contents into the surrounding eyelid tissues, provoking an intense inflammatory response, known as cellulitis. This causes marked redness and swelling of the eyelid and surrounding area. Oral antibiotics may be required if a secondary infection is suspected.
