Augmented vertical rectus transpositions: Intraoperative measurement of torsion following sequential muscle detachment

After vertical recti transposition surgery, a torsional change may occur. We hypothesized that step-by-step monitoring of the intraoperative torsional position of the eye can avoid any unexpected complications and identify critical moments of surgery that may have adverse effects.Nine patients with sixth nerve palsy that underwent complete transposition of the superior (SR) and inferior rectus (IR) muscles to the lateral rectus muscle by means...
