The Treatment of A and V Patterns by Monocular Surgery

Types of Pattern Strabismus and Their Surgical Outcomes after Adjustable Strabismus Surgery

“…Conventionally, in the absence of oblique over action, horizontal rectii are displaced, with medial rectus towards the apex of the pattern and lateral rectus away. [8][9][10][11] Monocular surgery with vertical displacement of the horizontal rectii was studied by Metz and Schwartz 8 with satisfactory results, and no subsequent torsional symptoms. These are good options for small patterns.…”

Torsion and Pattern Strabismus

“…Vertical transposition of the horizontal rectus muscles is a common procedure for treating alphabet patterns. It has been reported that this procedure does not cause any significant torsional change, 14,16 but most studies on this subject considered only subjective torsion. Because most patients undergoing a surgical procedure for horizontal strabismus associated with an A or V pattern do not have bifoveal fusion or diplopia awareness, a change in subjective torsion is not a good way to assess whether a torsional change has actually occurred after the operation.…”
