WEBINO (Walleyed Bilateral Internuclear Ophthalmoplegia) Syndrome in Progressive Supranuclear Palsy

ABSTRACT

WEBINO (walleyed bilateral internuclear ophthalmoplegia) syndrome is a rare disorder characterized by bilateral exotropia on primary gaze, bilateral internuclear ophthalmoplegia, and impaired convergence. It is mainly reported in patients with cerebrovascular diseases and multiple sclerosis, but rare cases have also been described in patients with neurodegenerative diseases such as progressive supranuclear palsy (PSP). We report WEBINO syndrome in a PSP patient.
