Dacryocystitis

What it means

Inflammation of the nasolacrimal sac.

Dacrocystitis is frequently caused by nasolacrimal duct obstruction or infection, which often results from stagnation of tears in a pathologically closed lacrimal drainage system. Note also that dacryocystistis has often been misspelled as dacrocystitis in the literature, but the correct spelling is dacryocystitis.
