Ocular myositis: insights into recurrence and semiological presentation

Abstract

Ocular myositis (OM) is a rare clinical entity characterized by idiopathic, nonspecific inflammation of primarily or exclusively extraocular muscles (EOM). Presentation usually encompasses painful diplopia, exacerbated by eye movement. We report two cases of idiopathic OM with unique characteristics. The first presented with pseudo-sixth nerve palsy due to medial nucleus inflammation and the second presented with recurrent OM, subsequently affecting both eyes. Knowledge of different patterns of presentation and recurrence are important to manage this rare inflammatory syndrome.
