Long-term follow-up of traumatic unilateral superior oblique palsy.

Twenty-four cases of traumatic unilateral superior oblique palsy were followed-up during a mean period of 5.3 years. Hypertropia in the primary position and a positive Bielschowsky test were present in 100% of the cases, compensating head posture in 71%, and excyclotorsion in 25%. Six patients needed surgical correction; 18 were cured spontaneously during a mean period of 9.2 months.
