Abstract

PURPOSE: To report a case of idiopathic orbital myositis involving all extraocular muscles bilaterally after trauma and to review current literatures on the orbital myositis.
METHODS
The idiopathic orbital myositis primarily involving the extraocular muscles is a subtype of nonspecific orbital inflammation. Pathophysiology of orbital myositis, although unknown, is likely to be an immune-mediated mechanism. A 17-year-old male presented with the orbital myositis involving all extraocular muscle after blunt head trauma.
RESULTS
Treatment of the idiopathic orbital myositis with oral corticosteroid and radiotherapy has been reported to be ineffective in cases involving 4 extraocular muscles. We herein report an experience of treating a case of orbital myositis involving all extraocular muscles with intravenous corticosteroid and radiotherapy.
