Acute dacryoadenitis is more commonly associated with which infection?

• A. Herpes simplex virus
• B. Staphylococcus aureus
• C. Pseudomonas aeruginosa
• D. Streptococcus pneumoniae

Answer: (B)

Acute dacryoadenitis is an acute infection of the lacrimal gland, presenting with sudden, tender swelling of the upper outer eyelid. The most common infectious agent in this setting is Staphylococcus aureus, a frequent cause of acute bacterial infections of the facial adnexa. Its appearance fits this scenario: localized, painful lacrimal gland swelling, often with fever or malaise, and rapid progression that responds to antibiotics targeting staph. Herpes simplex virus can affect the eyelids and conjunctiva but usually presents with viral conjunctivitis features or herpetic keratitis rather than a classic lacrimal gland infection. Pseudomonas aeruginosa is more commonly linked to contact lens–related keratitis or surface infections, not the typical lacrimal gland involvement. Streptococcus pneumoniae can cause conjunctivitis or sinusitis but is less commonly the culprit for acute lacrimal gland infection.
