title: Recurrent orbital myositis: report of a familial incidence.
abstract: BACKGROUND
  In orbital myositis, painful diplopia develops owing to an enlargement of the extraocular muscles. Diagnosis is established based on history, clinical manifestations, and therapeutic response to steroids, with the findings of magnetic resonance imaging providing additional information.
  
  
  METHODS
  We observed a family in which 4 members had an ophthalmopathy suggestive of orbital myositis. The affected members are a sibling pair (female and male) and 2 children of the brothers of their father's father.
  
  
  CONCLUSIONS
  The familial incidence suggests a potential genetic predisposition in the development of orbital myositis.
