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.
