Orbital cellulitis: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Orbital cellulitis may result from bacterial, fungal, or parasitic infection. It can develop from direct inoculation, via the bloodstream, or spread from adjacent structures. Periorbital tissues may be inoculated as a result of surgery, foreign body trauma, and even animal or insect bites. The most common pathogens in children are Haemophilus influenzae, Streptococcus pneumoniae, and Staphylococcus aureus. In young children, it’s spread from adjacent sinuses (especially the ethmoid air cells) and accounts for the majority of postseptal cellulitis cases. Immunosuppressed patients are also susceptible.

  • Hematogenous dissemination (rarely)

Cellulitis - etiology

  • S. aureus
  • Group A—hemolytic streptococci (S. pyogenes)
  • S. pneumoniae: Less common since the advent of childhood vaccination with heptavalent pneumococcal conjugate vaccine (Prevnar)
  • Group B streptococci (GBS), Gram-negative rods (GNR’s): neonates
  • HIB: Rare, due to childhood immunization
  • Pseudomonas aeruginosa, anaerobic bacteria: Immunocompromised children
