There have been many publications evaluating the visual outcomes of patients treated for orbital cellulitis. The aim of this study was to evaluate non-visual complications of post-septal orbital cellulitis (NVCOC) present 30 days after discharge from index hospitalization.This was an IRB-approved, retrospective chart review.Ninety patients (45 pediatric, 45 adults) were identified with OC. NVCOC were significantly more common in adult patients as compared to children (40.0% vs 15.6% respectively;Adult patients experience NVCOC complications more often than children. Furthermore, the nonvisual complications in children are more likely to resolve spontaneously than those in adults. The intracranial spread of infection is a significant risk factor for late complications in children. The presence of an orbital wall/floor implant is a significant risk factor for late complications in adults. There are many differences in the etiology, pathophysiology, and course of NVCOC in children and adults, so information on these two populations should be reported separately.
