Purpose:
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.
