Superior Oblique Tendon Tightening Procedures
The superior oblique tendon can be functionally divided into the anterior third, which is responsible for intorsion, and the posterior two-thirds, which is responsible for depression and abduction (Figure 18.1). Superior oblique tightening procedures are based on this physiologic division and either tighten the whole tendon (i.e., full tendon tuck) or tighten the anterior tendon fibers (i.e., the Harada-Ito procedure).
