Abstract

This case study describes a school-age child who developed orbital cellulitis following an upper respiratory infection. Orbital cellulitis is an infection of the orbital space, typically caused by an extension of an infection in the sinuses. While complications of upper respiratory infections are rare, they can be serious, and advanced practice nurses need to be alert for signs and symptoms that may indicate a complication.
