2.  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

3.  Obstruction of nasolacrimal duct leads to
stasis of nasolacrimal fluid-infection
 Staphylococcus aureus –most common
 Pneumococcus

4. 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

5.  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

6.  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.

7. MEDIAL
PALPEBRAL
LIGAMENT

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

11.  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
