to evaluate the clinical characteristics, histopathology and treatment outcomes in adult and pediatric patients with Idiopathic orbital inflammation

This prospective study evaluates the demographics, clinical presentation, imaging and histopathologic features, and treatment outcomes of 76 patients with IOI

The mean age was 41.68±17.62 (with a range of 6 to 75 years) The most common signs and symptoms were periorbital pain, periorbital edema, decreased ocular movements or diplopia and conjunctival injection. The most common site of involvement either in adults or in pediatrics was the lacrimal gland and extraocular muscles. Most of the pateints were treated by oral corticosteroids. Duration of follow up was 7.00±6.45 months. Recurrence occurred in 9 (11.8%) of patients during the follow up period

IOI is a clinical syndrome which presents a vast group of signs and symptoms. Some of its features may differ between adults and children. Biopsy should be done particularly in atypical or treatment resistant patients. In most patients, treatment especially with corticosteroids is needed to resolve the clinical findings
