Periorbital and orbital cellulitis in children.
The clinical and laboratory data  on 87 cases of orbital and periorbital cellulitis were reviewed. Two distinct clinical presentations were encountered. One group of 45 patients had no history of trauma or apparent focus of infection. Blood cultures on these patients were positive in 34%. Haemophilus influenzae accounted for 82% of the positive blood cultures. This group of patients shares common features with children who have facial cellulitis due to H. influenzae type b. The second group consisted of 42 patients with adjacent soft tissue focus of infection. There was only one positive blood culture in this group. Staphylococcus aureus and/or group A beta-hemolytic Streptococcus were isolated from conjunctival or wound exudate in the majority of these patients. Thirteen patients with orbital cellulitis were encountered among the 87 cases. These patients were older and had a higher incidence of demonstrable sinus disease when compared with the overall group. The pathophysiology of orbital and periorbital cellulitis is reviewed and an approach to the management of these disorders is formulated.
