The Spectrum of Idiopathic Orbital Myositis: Clinical and Echographic Findings

We performed a retrospective chart review on seventy? five patients, age 9-84, with idiopathic orbital myositis. Females were affecttd more than mice as often as males. The majority of patients (68%) had single muscle involvement, with the later and medial recti affected most frequently (33.% and 29/o of yes, respectively). Forty-five percent of affected muscles functioned normally, while the remainder were farrly equally distnbuted between paretic, restncllve, or combined paretic-restrictive myopathies
