Motion diplopia in an isolated unilateral internuclear ophthalmoplegia: A new neurological symptom?

The MLF carries afferents from abducens internuclear neurons to the medial rectus subdivisions of the contralateral oculomotor nucleus, in addition to vestibular and smooth pursuit afferents from neurons in the vestibular nuclei to midbrain nuclei related to vertical gaze [3]. [...]MLF lesions may c...

Description
Summary:The MLF carries afferents from abducens internuclear neurons to the medial rectus subdivisions of the contralateral oculomotor nucleus, in addition to vestibular and smooth pursuit afferents from neurons in the vestibular nuclei to midbrain nuclei related to vertical gaze [3]. [...]MLF lesions may cause limitation of adduction, or skew deviation to cause diplopia that is horizontal, or oblique [4]. [...]we hypothesis that motion diplopia must follow dysconjugate eye movements during smooth pursuit, either due to decreased velocity of the adducting eye, or abducting nystagmus and hypermetria of the abducting eye.
