Limitation of opposing ductions following augmented horizontal rectus muscle transposition.
OBJECTIVE
To report the effect on ductions in opposing gaze following augmented horizontal rectus muscle transposition to treat cyclovertical muscle palsies.


METHODS
Record review of 5 patients who underwent augmented horizontal rectus muscle transposition for treatment of vertical gaze misalignment secondary to cyclovertical muscle palsy.


RESULTS
Ductions in the direction of the palsied muscle improved in all patients. Four patients (80%) developed significant limitation of vertical gaze in the direction opposite that of the palsied muscle.


CONCLUSIONS
Augmented transposition surgery for vertical muscle palsy can produce considerable limitation of ductions in the direction opposite to that of the paralyzed muscle.
