[Cure of post-traumatic bilateral paralysis of the cranial nerve IV].

We relate our own experience about bilateral inferior rectus recession as first surgery for traumatic bilateral superior oblique palsy. An adjustable suture is performed on one side. This procedure is combined or not with an inferior oblique recession. Measurements of ocular deviation and torsion, Lancaster tests and binocular single vision fields are reported pre- and postoperatively. Reduction of diplopia, cyclodeviation and V esotropia with an expansion of the binocular single vision field is achieved in all cases, relieving patients' complaints. This surgery is easy to perform and free of important secondary effects. We think it represents a valuable choice for that kind of pathology.
