What is another term for a sty, which is an infection of the eyelash follicle?

A sty, an infection of an eyelash follicle, is medically referred to as a hordeolum. This term specifically describes a localized infection that typically presents as a painful, swollen lump on the eyelid, resulting from the obstruction and inflammation of the oil glands associated with the hair follicles of the eyelashes.

On the other hand, a chalazion is a blockage of the oil gland that does not involve an active infection and often appears as a painless lump. Pinguecula is a yellowish, raised growth on the conjunctiva that does not affect the eyelashes or indicate infection. Conjunctivitis refers to the inflammation of the conjunctiva, commonly known as pink eye, which can result from infections or allergies but is unrelated to the specific infection of the eyelash follicle. Therefore, the term hordeolum is the accurate medical designation for a sty, distinguishing it from these other conditions.
