Acute dacryocystitis is an infection of the nasolacrimal system characterized by erythema, swelling, warmth, tenderness of the lacrimal sac, and/or purulent discharge. It is a rare complication of isolated congenital nasolacrimal duct obstruction but occurs commonly with dacryocystoceles. Acute dacryocystitis can be complicated by preseptal or orbital cellulitis, sepsis, or meningitis and should be treated promptly with antibiotics. Admit and consult Ophthalmology for further treatment recommendations.
