Orbital and Preseptal Cellulitis

Nomenclature:

  • The orbital septum defines the boundary between the orbital cavity and the skin covering the eye and orbit.
  • Orbital cellulitis = post-septal cellulitis.  The preferred term is “orbital cellulitis.”
  • Preseptal cellulitis = peri-orbital cellulitis.  The preferred term is “preseptal cellulitis.”

Orbital cellulitis is a much more serious infection due to the limited space of expansion within the confining skull bones.

Etiology:  the bacteria are sinus bacteria – M cat, H flu, S pneumo.  H flu is not that common anymore – untypeable H flu can still be seen.

Complications of preseptal cellulitis:  extension into orbital cellulitis, cavernous sinus thrombosis, extension into frontal sinus and frontal lobe.
