Transposition surgery for WEBINO.

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rare syndrome which is characterized by a set of ocular motility abnormalities, especially a large-angle exotropia in primary gaze. One of the management strategies suggested for it is extraocular muscle surgery, particularly transposition surgery. In this 38-year-old male WEBINO patient, we concluded that transposition surgery could effectively alleviate the exodeviation and also the patient's complaints in comparison with resection-recession procedures.
