The length and source of the trochlea nerve causes it to be one of the most vulnerable of the cranial verves. A retrospective study of the long term muscle sequelae of 32 fourth nerve palsies, both congenital and acquired, was undertaken examine the development of concomitance with time. Particular reference has been made to the increased dysfunction of the contralateral superior rectus muscle, compared with that of the primary palsy.
