Unilateral periorbital swelling in children: avoid delays in diagnosis

Abstract

A 10-year-old child had painful periorbital swelling in the left eye. It was diagnosed as preseptal cellulitis and treated with oral antibiotics. Three days later, the ocular condition worsened so the child was referred for further management. On examination, the child had a temperature of 102\u2009°F. Ocular examination revealed proptosis, restricted ocular movements and a relative afferent pupillary defect in the left eye. Ocular examination of the right eye was normal. There was a history of recurrent episodes of cold in the past. CT scan orbit and sinuses revealed signs of orbital cellulitis with sinusitis on the left side. The child was treated with parenteral antibiotics and endoscopic sinus surgery. A child presenting with unilateral periorbital swelling needs to be thoroughly evaluated. It is important to differentiate orbital cellulitis from preseptal cellulitis. Orbital cellulitis is an emergency and delay in diagnosis can lead to vision and life-threatening intracranial complications.
