Orbital cellulitis is rarely reported after strabismus surgery; fewer than 10 cases have been reported. Nonetheless, orbital cellulitis is a potentially sight- and life-threatening condition. A high index of suspicion, use of a multidisciplinary approach, early diagnosis, aggressive treatment, and close monitoring are all important means of avoiding potentially irreversible visual loss and systemic complications. We report a case where early use of aggressive treatment to manage a post-strabismus surgery infection led to a good outcome.
