When an Orbital Infection Isn't Infectious at All: A Review of Orbital Inflammatory Syndrome.

Orbital inflammatory syndrome (OIS) includes a wide range of clinical manifestations and may initially be misdiagnosed as orbital cellulitis due similar symptoms of fever, periorbital swelling, and pain with eye movements. A diagnosis of OIS requires evaluation for underlying systemic disorders including autoimmune disorders and thyroid disease. Symptoms typically improve rapidly after initiation of steroid therapy, although recurrence can occur. This article presents an illustrative case of a 13-year-old girl with OIS.
