Abstract
Acute dacryocystitis is not uncommon in oculofacial and general ophthalmology clinics admissions. It happens with sudden inflammation of lacrimal sac that frequently occurs in the setting of pre-existing nasolacrimal duct obstruction. Long standing tear flow stasis results in change of bacterial flora and bacterial over-growth in the lacrimal sac as a reservoir of stagnant tear., However, acute dacryocystitis can be associated with dacryoliths or indefinite pre-existing anatomic nasolacrimal duct obstruction.
