Excyclotorsion in Congenital Fibrosis of Extraocular Muscles

Abstract

The authors report marked bilateral excyclotorsion contributing to loss of binocularity and leading to ipsilateral head tilt in a patient with congenital fibrosis of the extraocular muscles type 1. Neuroimaging revealed bilateral hypoplastic superior recti and levator palpebrae superioris muscles. Postoperatively, head tilt was relieved and excyclotorsion was reduced. Assessment of torsion may influence surgical strategies and outcome in patients with congenital fibrosis of the extraocular muscles.
