  Fig. 1 Computerized tomography (CT) scan, gaze photography, fundus photography, and intraoperative findings. (A) CT scan of the skull with 3-dimensional reconstruction showing improvement in dysmorphic asymmetry of the orbits with expansion cranioplasty for right coronal suture synostosis (left and middle). Coronal images from orbital CT scan showing presumed retroplacement of the trochlea of the right orbit given that the right superior oblique is less visible at the equator of the globe (red circle) than at the posterior of the globe (right). (B,E) Versions showing right inferior oblique overaction, right hypertropia that was aggravated by right head tilt, and preference for left head tilt before surgery, consistent with right superior oblique palsy (B). (E) Normalization of motility and head posture one year after surgery. Fundus photographs showing (C) excyclotorsion in the right eye before surgery and (F) improvement one year after surgery. (D) The right eye was supra-ducted with a muscle hook placed under the inferior oblique muscle. A fibrous band was found between the right lateral rectus muscle and the right inferior oblique muscle (white arrow). Written informed consent for publication of their images was obtained from the parent of the patient.
