Vertical effect of the adjustable Harada-Ito procedure.
The adjustable Harada-Ito procedure, as described by Metz, was performed on four patients. A hypotropia of 10 to 12 prism diopters (PD), in addition to incyclotorsion, was induced in two patients in whom the superior oblique tendon was split 8 mm, only enough to permit mobilization to its new location. Splitting the tendon for 15 mm eliminated the induced hypotropia while preserving incyclotorsion.
