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.

Abstract
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.File | Dimensione | Formato | |
