Abstract

Background： Wall-eyed bilateral internuclear ophthalmoplegia syndrome (WEBINO) is a rare disorder comprising bilateral exotropia, bilateral internuclear ophthalmoplegia, and impaired convergence. It is usually caused by a midbrain lesion. Case presentation ：We describe a rare case of WEBINO, with the lesion located in the lower pons, in a 69-year-old man with acute ischemic stroke. Conclusions ：Our report alerts physicians to the possibility of bilateral WEBINO due to unilateral infarction.
