Neurologist Explains Internuclear Ophthalmoplegia (INO)

In this video, I show what an INO looks like and explain the neuroanatomy behind it. We also look at common causes of INO, and I show some case reports with accompanying MRI scans. At the end, we discuss related topics including "one and a half syndrome," "eight and a half syndrome," WEBINO, and pseudo-INO.
