Conclusions. Orbital cellulitis is a rare complication of orbital fracture, and seems to be more common when paranasal sinus infection preexists or occurs within several weeks of the injury. Oral antibiotics given after the orbital injury may not prevent orbital cellulitis or abscess formation.
Infection Investigation. Preseptal cellulitis refers to the infectious involvement of the eyelid and periorbital soft tissue anterior to the orbital septum. Conversely, orbital cellulitis is the infectious involvement of tissue posterior to the orbital septum, including the fat and muscle within the bony orbit. The distinction is important because a delay in diagnosing orbital cellulitis may be associated with visual and life-threatening sequelae.
