Chalazions are granulomatous inflammations of the meibomion gland. These glands produce the lipid component of the tear film and are deeply located within the supporting tarsal plate of the lid. Chalazions occur when meibomian gland pores become clogged (such as in blepharitis) — lipid backs up into the gland, and a noninfectious inflammatory granuloma reaction occurs.
On exam, the patient will have a firm and mobile nodular bump on their eyelid. When you evert the lid, you’ll often see the chalazion bump more clearly. They are non-tender and are not painful.
Early treatment involves warm compresses, massage, and lid scrubs in an attempt to reopen the meibomian pore and allow the material to flow out. If this doesn’t work, we flip the lid and incise/drain the chalazion from the inner eyelid surface. Some people are more prone to developing chalazions and they tend to reoccur.
