I pazienti con problemi vestibolari centrali possono manifestare in questi test molti segni/sintomi come vertigine ("vertigo"), nausea, nistagmo, oscillopsia
, atassia, e disequilibrio.
Acute or subacute unilateral vestibular failure, characterised by rotational vertigo, oscillopsia
, and a tendency to fall toward the affected ear - usually acute vestibular neuritis.
The most common symptoms include: rotatory vertigo, apparent body tilt, oscillopsia
(positional nystagmus), nausea and tendency to lose balance in a direction opposite to the vertigo.
Blurry vision, oscillopsia
, transient opsoclonus, and cognitive impairment may be present (4, 5).
A 41-year-old man was referred to our tertiary care otoneurology center for evaluation of dizziness, oscillopsia
, deafness in the right ear, and disabling tinnitus in the presence of normal hearing in the left ear.
can occur with ataxic nystagmus; more rarely there are nuclear or infranuclear III, IV or VI nerve palsies and gaze palsies.
The most common symptom is dizziness, which is usually accompanied by vertigo, loss of balance, diplopia, nystagmus, oscillopsia
, weakness in both legs, hemiparesis, gait ataxia, and numbness (3, 6).
20-21) Patients may also experience oscillopsia
, reading fatigue and loss of stereopsis.
It is encouraging, though, that none of the caregivers of the children in our study reported any signs of dizziness, vertigo, or symptoms of bilateral peripheral vestibular loss, including imbalance, ataxia, and oscillopsia
immediately following or in the several months after their use of the neomycin/polymyxin B/hydrocortisone drops.
is usually absent, but may be reported in far lateral gaze or under stress, when the nystagmus is more intense than usual (for the patient).
Typical symptoms include sound- or pressure-induced vertigo, disequilibrium, oscillopsia
, autophony, aural fullness, and hearing loss.
Most otolaryngologists do not have a close familiarity with clinical tests such as the head-shake test, the oscillopsia
(dynamic visual acuity) test, the high-frequency horizontal head-thrust (Halmagyi) maneuver, and the head-heave translational otolithic maneuver.
