What is the name for a granulated inflammation of the eyelid that may require surgical excision if it does not subside?

A chalazion is a localized, chronic granulated inflammation of the eyelid caused by the blockage of a meibomian gland. It typically presents as a firm, painless swelling on the eyelid. While many chalazia resolve on their own, some may require intervention such as surgical excision if they persist despite conservative treatments.

In contrast, a stye, which is also known as a hordeolum, usually presents as a painful, acute infection of the eyelash follicle or meibomian gland and typically resolves with warm compresses and antibiotic treatment rather than surgery. Blepharitis refers to inflammation of the eyelid margins which is often due to seborrheic dermatitis or bacterial infection, requiring management rather than surgery. A pterygium, which is a growth of tissue on the conjunctiva, may also require surgery for removal in certain cases, but it is not classified as a granulated inflammation of the eyelid. Thus, the distinct characteristics of a chalazion align with the necessity for potential surgical intervention if it does not resolve.
