PURPOSE To determine the best treatment for dissociated vertical deviation (DVD). METHODS The authors investigated the postoperative results of unilateral surgery for DVD in 14 patients when the visual acuity difference between the two eyes did not result in a postoperative dominance switch. All patients underwent bilateral medial rectus recession for congenital esotropia. RESULTS With this unilateral surgical procedure, all patients showed a significant improvement of the DVD in the primary position. None of the patients developed hypotropia, anti-elevation syndrome, or inferior oblique overaction in the contralateral (dominant) eye, and no changes were observed in the contralateral eye. CONCLUSIONS Unilateral surgery for DVD in the non-dominant eye in case of strong fixation preference does not create a postoperative manifest DVD in the unoperated dominant eye.
