ⓘ Harada–Ito procedure

The Harada–Ito procedure is an eye muscle operation designed to improve the excyclotorsion experienced by some patients with cranial nerve IV palsy. In this procedure, the superior oblique tendon is split, and the anterior fibers – the fibers most responsible for incyclotorsion – are moved anteriorly and laterally. This selectively stretches and tightens these fibers, enhancing the incyclotorsion power of the superior oblique.

The most common indication for Harada–ito procedure for acquired bilateral cranial nerve IV palsy after closed traumatic brain injury, especially car accident. In this clinical situation the vertical imbalance is often less symptomatically bothersome to the patient than the induced excyclotorsion. Affected patients are particularly annoying type of diplopia double vision in which the images of twisted excyclotorted.

Patients with cranial nerve IV palsy whose complaints are not specifically limited to torsional diplopia, but instead also have a significant vertical diplopia, are not good candidates for Harada–ito procedure. Instead, the recession of the lower oblique muscle, or other operation strabismus can be specified.
