This disease is characterized by the inability to elevate the adducted eye actively or passively. There is less elevation deficit with the eye in midposition, and minimal or no deficit in abduction. Brown syndrome accounts for approximately 2% of strabismus cases. Ten percent of cases are bilateral, and left- and right-sided unilateral cases are equal in frequency.
