This document discusses dacryocystitis, which is an inflammation of the lacrimal sac. It is often caused by an obstruction of the naso-lacrimal duct followed by a bacterial infection. It can be either acute or chronic, and is classified based on whether it is acquired or congenital. Acute dacryocystitis causes pain, redness, and swelling and risks include older age and poor hygiene. Chronic dacryocystitis causes watering, mucopurulent discharge, and regurgitation of pus or mucus with pressure. Treatments include antibiotics, warm compresses, and surgery.

2. DACRYOCYSTITIS
• Inflammation of lacrimal sac
• Often caused by obstruction of
naso-lacrimal duct
• Followed by bacterial infection.

3. ANATOMY- Lacrimal apparatus

5. TYPES
ACUTE CHRONIC
ACQUIRED CONGENITAL
CLASSIFICATION

6. CAUSES
• NLD block due to narrowness or chronic
inflammation of sac .
• Nasal polyps .
• Following primary conjunctivitis .
• Infection spreading from nasophraynx .
• Organisms responsible : Pneumococcus ,
streptococcus , staphylococcus , mycobacterium ,
etc ,...

7. ACUTE DACRYOCYSTITIS
 RISK :
 Older patients bcoz lacrimal drainage system loses its
elasticity
 Poor hygiene
 SYMPTOMS :
 Pain
 Redness
 Swelling over inner aspect of lower eyelid
( can lead to orbital cellulitis )

8. Acute

9. CHRONIC DACRYOCYSTITIS
 RISK :
 Postmenopausal women – spontaneous or follow
lacrimal sac infection .
 Infants – bcoz of failure of NLD to open into inferior
meatus .
 SYMPTOMS :
 Watering
 Mucopurulent discharge
 Regurgitation of pus / mucopus through puncta on
pressure over the sac area .

10. CHRONIC

11. COMPLICATIONS
• Fistula formation
• Lacrimal sac abscess
• Orbital cellulitis
• Meningitis
• Cavernous sinus thrombosis

12. TREATMENT
 ACUTE :
• Systemic antibiotics
• Warm compresses and gentle massage
• Local incision drainage if abscess formed .
 CHRONIC :
• Repated syringing
• Dacryocystorhinostomy
• Dacryocystectomy
