What is dacryocystitis another name for?

Dacryocystitis refers specifically to an inflammation or infection of the lacrimal sac, which is part of the tear drainage system. The term is derived from "dacryo," meaning tear, and "cystitis," meaning inflammation of a sac or cyst.

Blepharitis, while also a significant eye condition, involves inflammation of the eyelid margins, and is distinct from dacryocystitis. Conjunctivitis, or pink eye, is an inflammation of the conjunctiva, which is the membrane covering the eye and inner eyelids. A hordeolum, commonly known as a stye, is an acute, localized infection of an eyelid gland. Astigmatism, on the other hand, is a refractive error concerning how the eye focuses light, not an inflammatory condition.

Therefore, recognizing that dacryocystitis pertains specifically to the lacrimal system helps clarify why it is distinct from these other conditions.
