Dacryocystitis

Dacryocystitis is an infection of the lacrimal sac, usually secondary to obstruction of the nasolacrimal duct. It manifests as inflammation, pain, and swelling in the medial canthal region. It occurs in acute and chronic forms and requires prompt management to prevent orbital cellulitis.

The primary cause is stasis of tears within the lacrimal sac due to nasolacrimal duct obstruction (NLDO). Bacterial overgrowth typically follows, with Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae being the most common pathogens.

Obstruction of the nasolacrimal duct leads to stagnation of lacrimal secretions. This stagnant fluid provides a medium for bacterial colonization. The subsequent inflammatory response causes localized edema, distention of the lacrimal sac, and suppuration. In acute cases, this can progress to abscess formation and fistula.

Most common in infants (congenital NLDO) and adults over

1. Females are more frequently affected than males, likely due to narrower bony nasolacrimal canals.

• Nasolacrimal duct stenosis or obstruction
• Facial trauma or nasal surgery
• Chronic rhinosinusitis
• Advanced age
• Autoimmune disorders (e.g., Sarcoidosis)

A. Early Symptoms

• Epiphora (excessive tearing)


• Mild tenderness near the medial canthus B. Common Symptoms


• Erythema and edema over the lacrimal sac


• Purulent discharge


• Tenderness on palpation of the sac C. Advanced Symptoms


• Abscess formation


• Conjunctival injection


• Low-grade fever D. Emergency Symptoms


• Proptosis


• Ocular motility restriction


• Severe, radiating orbital pain

Inspection reveals a swollen, erythematous, tender mass located inferior to the medial canthal tendon. Digital pressure may express mucopurulent material from the puncta.

A. Clinical Assessment: Primarily clinical diagnosis.
B. Laboratory Testing: Culture of regurgitated material.
C. Imaging Studies: Computed Tomography (CT) for suspected orbital involvement.
D. Functional Tests: Dye disappearance test.
E. Biopsy Findings: Usually unnecessary unless neoplasia is suspected.
F. Genetic Testing: N/A.
G. Differential Diagnosis: Dacryocystocele, ethmoid sinusitis, preseptal cellulitis.

Conjunctival/Sac Swab
Type: Microbiology Culture
Purpose: Identify causative organism for targeted antibiotic therapy.
Expected Findings: Growth of Staph or Strep species.
Interpretation: Directs sensitivity-based pharmacological intervention.

Orbital CT with contrast: Indicated when systemic signs or suspicion of orbital extension arise. Findings include distended lacrimal sac, inflammation, and possible abscess. Essential for differentiating from orbital cellulitis.

• Preseptal cellulitis (no epiphora/sac distension)
• Acute ethmoid sinusitis (deep nasal pain)
• Lacrimal sac malignancy (firm, painless, chronic mass)

Orbital cellulitis, cavernous sinus thrombosis, lacrimal fistula, chronic conjunctivitis.

A. Lifestyle Modifications: Warm compresses.
B. Preventive Measures: Daily eyelid hygiene.
C. Medical Treatment:

• Systemic Antibiotics: Cephalexin, Amoxicillin-Clavulanate.


• Topical Antibiotics: Moxifloxacin or Ofloxacin drops.

Good with prompt intervention. Chronic cases require surgical correction of duct obstruction to prevent recurrence.

Early treatment of underlying nasolacrimal duct obstruction and management of chronic sinus congestion.
