    8. Eye Deviation
  2. Pathophysiology
    1. Medial Longitudinal Fasciculus (MLF) - normal function
      1. On lateral gaze, Cranial Nerve 6 abducts the ipsilateral eye
      2. To maintain Conjugate Gaze, a signal is passed via MLF to the contralateral eye's CN 3 to adduct (medially) in parallel
    2. With a MLF lesion, the adducting eye via CN 3 fails to adduct
      1. In response, the abducting eye (via CN 6) demonstrates Nystagmus and Conjugate Gaze Palsy
    3. Extraocular Movement is normal in other directions
      1. Primary gaze remains parallel
      2. Eye convergence on near Vision remains intact
  3. Causes
    1. Older adults (esp. unilateral involvement)
      1. Vascular disease affecting the vertebrobasilar circulation
    2. Young adults (esp. bilateral involvement)
      1. Multiple Sclerosis
    3. Children
      1. Pontine glioma (MRI)
      2. Vasculitis may also cause Internuclear Ophthalmoplegia in this age group
    4. Alcoholism
      1. Wernicke's Encephalopathy
