2 Cases of Traumatic Inferior Oblique Palsy

ABSTRACT

PURPOSE: Inferior oblique palsy is the least commonly isolated extraocular muscle palsy. We describe the clinical features and managements of 2 cases of traumatic inferior oblique palsy. METHODS: Two adult patients were presented with vertical diplopia and head tilt posture after head trauma. The subjects fulfilled the three-step test criteria, with a hypertropia that worsened on side gaze and head tilt away from the affected eye. They showed free forced duction to elevation in adduction. Both were treated by ipsilateral superior oblique tenotomy and contralateral superior rectus recession with adjustable suture technique. RESULTS: During postoperative 7 month observation, both patients demonstrated orthophoria in primary gaze. Our surgical procedures eliminated the diplopia and abnormal head tilt posture, thereby achieving satisfactory results.
