Orbital cellulitis (&/or abscessation) describes inflammation of any of the periocular tissues. Findings may include blepharospasm, conjunctivitis, chemosis, third eyelid elevation, ocular discharge, deviation of the globe from its normal position, secondary exposure keratitis, periocular swelling/fluctuance and/or difficulty opening the mouth as a result of pressure placed on inflamed retrobulbar soft tissues by the ramus of the mandible. Symptoms typically develop relatively rapidly (over the course of several days). This process may result from trauma, penetrating wounds, extension of inflammation/infection from adjacent tissues (such as dental disease), the presence of foreign material and/or neoplasia.
