This chapter reviews clinical features of eye movement disorders
associated with vestibular disorders. The clinical history and
examination are reviewed, pointing our key symptoms and signs (with
illustrative video cases), for example, in distinguishing vertigo due
to stroke from peripheral vestibular disease. Acute vertigo is
discussed, including forms due to infections, trauma, and toxins as
well as Tullio phenomenon, fistula, canal dehiscence. Recurrent
vertigo is reviewed, including Ménière’s syndrome, otosclerosis,
inflammatory disorders, migraine, vascular disorders, and epilepsy.
The mechanism of hyperventilation-induced vertigo and nystagmus is
discussed. Posturally induced vertigo is reviewed, detailing features
and treatment of benign paroxysmal positional vertigo (BPPV), and
central causes of positional vertigo. The symptom of oscillopsia is
reviewed, whether due to an abnormal vestibulo-ocular reflex or
paresis of extraocular muscles, or due to nystagmus and other abnormal
eye movements. Finally, the topological diagnosis and pathogenesis of
skew deviation and the ocular tilt reaction are discussed.
