title: Cycloduction as a possible side-effect of vertical transposition of horizontal eye muscles in A- and V-pattern.
abstract: In general an A-or V-symptom is an additional sign of an oblique muscle dysfunction and is treated by surgery of oblique muscles. The vertical transposition of horizontal rectus muscles is a suitable treatment only in those cases with no coexistent vertical deviation. The mechanical particularities of this vertical displacement are summarized. Possible side effects of this surgical method, including cyclotropia are reported.
