title: A case of relapsing flitting bilateral idiopathic orbital inflammation.
abstract: Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles.
