The effect of anterior transposition of the inferior oblique muscle on ocular torsion

Dose–response relationship in inferior oblique muscle recession

“…This may be explained by slow fading of pre-operatively existing compensatory mechanisms [7,20,42]. For cases with additional anteroposition, the decrease of torsional effect was statistically significant, as described by others [41].…”

The effect of surgical treatment of superior oblique muscle palsy on ocular torsion

“…[4][5][6] In the present study we evaluated the effectiveness of various surgical techniques (superior oblique tucking and inferior oblique weakening, including anterior transposition of the inferior oblique muscle, inferior oblique recession, and inferior oblique myectomy) on objective and subjective torsion in patients with superior oblique palsy.…”

Anterior and Nasal Transposition of the Inferior Oblique Muscle for Iatrogenic Superior Oblique Palsy

“…However, the large amount of excyclotorsion, especially on downgaze, was unlikely to be eliminated even if the IO was placed adjacent or anterior to the inferior rectus insertion. 6 Dealing with residual torsion would have been difficult as the SO tendon damage precluded SO transposition surgery. Although horizontal transposition of the vertical recti was an alternative, this technique effectively corrected both the vertical and torsional components in 1 step, with sparing of the ciliary circulation and a more predictable result.…”
