Paediatric orbital and periorbital infections

Purpose of reviewThis study is a review of recent literature in the diagnosis and management of preseptal cellulitis, orbital cellulitis and dacryocystitis, including causative organisms, diagnosis and medical or surgical therapy and potential complications.Recent findingsAdvances in vaccination against Haemophilus influenzae B have resulted in a shift in the most common causative organisms of preseptal and orbital cellulitis. Management of orbital cellulitis has been advanced by adjuvant corticosteroids, and subperiosteal abscess volumes of more than 1250ml has been shown as predictive for requiring potential surgical intervention.SummaryPeriorbital infections require prompt evaluation and management. Although the infectious organisms in both preseptal and orbital cellulitis include Staphylococcus/Streptococcus species, management may differ significantly on the basis of the nidus of infection, presenting signs and symptoms, and response to initial medical management.
