Look for signs of vestibular neuronitis. Nystagmus is present and is usually fine horizontal but may be mixed horizontal-torsional with the fast phase away from the affected ear. It always beats in the same direction (unidirectional), even if the head is rotated, and is reduced when the vision is fixed on a point.

Vestibular neuritis refers to a disorder characterized by acute, isolated, spontaneous vertigo due to unilateral vestibular deafferentiation.[] Even though the clinical features had been described previously, it was Dix and Hallpike who first coined the term vestibular neuronitis in 1952 to distinguish it from Ménière's disease.[] This is a 25-year-old woman who experienced the acute vestibular syndrome due to right-sided vestibular neuritis 1 week prior to this video. Left-beating nystagmus (LBN) was only noted in left gaze, but with fixation-removed, there was clear LBN in primary position that increased with head-shaking and vibration. The retinal bleach effect from sustained light exposure blocks fixation of the uncovered eye and enhances a latent vestibular nystagmus.27 Frenzel’s goggles and other recently designed portable goggles are additional options.28 Typically, peripheral vestibular lesions are associated with unidirectional nystagmus that increases in the gaze direction of the fast phase (Alexander’s law). Vestibular Neuritis: Vestibular sedatives can be used early on, for short periods of time, but should be tapered down over several weeks (Post, 2010). For long-term use, a vestibular sedative is not recommended, as it prevents central compensation and slows recovery (Lee, 2012).

Vestibular neuritis derives its name from the labyrinths that house the vestibular system, which senses changes in the head's position or the head's motion. Nystagmus •The vestibular system is a balanced system. •Effects of activity from one vestibular organ are balanced by effects from the other.

Vestibular neuritis is the most common cause of the acute vestibular syndrome, which is characterized by continuous vertigo and spontaneous nystagmus lasting days. It may be mimicked by central causes, including stroke, but in the hands of subspecialists, the HINTS+ (Head Impulse, Nystagmus, Test of Skew, where + is the addition of a bedside finger rub assessment of hearing) examination can These are the quick saccade movements that occur in patients with vestibular issues.

Vestibular neuronitis (sometimes called vestibular neuritis) is a disorder characterised by acute, isolated, spontaneous, and prolonged vertigo of peripheral origin. The terms 'vestibular neuronitis' and 'labyrinthitis' have been used interchangeably in the past, but specific terminology is now recommended by experts.

These are the quick saccade movements that occur in patients with vestibular issues. There is a fast followed by slow movement and the nystagmus is named for the direction of the fast component. No nystagmus is considered normal. Now have the patient look to the left and right.

This will present as a horizontal nystagmus that beats away from the affected ear (toward the unaffected year), and will not change direction with the direction of gaze.
