What nonrheumatologic conditions are associated with orbital inflammatory disease?
Thyroid eye disease is the most common cause of OID overall, representing half of cases. Other diseases associated with OID include ocular lymphoma/lymphoproliferative disease, metastatic disease affecting the orbit, and Tolosa–Hunt syndrome. Idiopathic disease (also referred to as idiopathic orbital inflammation ) can be a common cause of OID and is a diagnosis of exclusion.
