Acute suppurative bacterial dacryoadenitis: a case series.

Background: We present a series of patients with acute suppurative bacterial dacryoadenitis and review the clinical presentation, microbiology, treatment options and outcome.

Methods: A multicentre, retrospective, case series review of patients with a clinical diagnosis of acute bacterial suppurative dacryoadenitis (ASBD). Records were examined to obtain information regarding patient demographics, presenting symptoms and signs, radiology, microbiology, management, outcomes and follow-up.

Results: 11 patients (9 men, 2 women; mean age 43.9 years, range: 6-82 years) were included. Average time to presentation was 2.8 days, and predisposing conditions were found in 45% of cases. Common presenting symptoms were eyelid swelling, pain, redness and diplopia, and common signs were ptosis, discharge and restriction of eye movements. The most common causative bacteria were Staphylococcus aureus and skin flora. Lacrimal gland swelling was universally seen on CT, with globe indentation of displacement in 27% of cases. Intravenous antibiotics were used in 91% of cases, which subsequently resolved over an average period of 9.7 days. Those with abscess formation (n=2) required incision and drainage.

Conclusions: ASBD is a rare condition that resolves quickly if managed appropriately. Underlying anatomical, infectious or inflammatory conditions should be investigated, and skin commensals should be covered with the instigation of antibiotic therapy.
