Acute dacryocystitis is an inflammation of the lacrimal sac, characterized by painful swelling below the inner eye corner. It is caused by an obstruction of the nasolacrimal duct leading to infection, most commonly by Staphylococcus aureus or pneumococcus bacteria. If left untreated, the infection can progress through stages of cellulitis, abscess formation, and fistula formation draining pus externally or internally into the nasal cavity.

Acute dacryocystitis is an acute suppurative inflammation of the lacrimal sac, characterized by presence of swelling in the region of sac The term derives from the greek dakryon(tear),cysta(sac),and it is(inflammation) The onset is acute,and there is painful swelling below the inner canthus,often combined with cellulitis
Obstruction of nasolacrimal duct leads to stasis of nasolacrimal fluid-infection Staphylococcus aureus most common Pneumococcus
3 Stages Stage of cellulitis Stage of lacrimal abscess Stage of fistula formation Risk factor Age-more common between 40-60 years(lacrimal drainage system loses its elasticity) Poor personal hygiene
Characterized by a painful swelling in the region of lacrimal sac Associated with epiphora,fever and malaise Swelling is red,hot,firm and tender Redness and edema spread to the lips and cheek When treated resolution may occur
Continous inflammation causes occlution of the canaliculi due to oedema The space is filled with pus,distends and its anterior wall ruptures forming a pericystic swelling-large lacrimal abscess formed Points below and outer side of the sac-due to gravitation of pus & medial palpebral ligament in the upper part.

When lacrimal abscess is left unattended- discharge spontaneously-external fistula below medial palpebral ligament Rarely, abscess may opens into the nasal cavity- internal fistula

Acute conjuntivities Corneal abrasion which may converted into corneal ulcer Lid abscess Osteomyelitis of lacrimal bone Orbital cellulitis Facial cellulitis Rarely cavernous sinus thrombosis can occur
