622 Possible Causes for Horizontal Nystagmus

  • Nystagmus

    […] angle analysis is helpful in differentiating between horizontal nystagmus and mixed nystagmus with horizontal and vertical components.[ncbi.nlm.nih.gov] We attribute head-jolting nystagmus to dislodged material within the horizontal semicircular canal and provide a mechanistic model to explain its origin.[ncbi.nlm.nih.gov] PPN usually presents as persistent downbeating nystagmus during head hanging or as apogeotropic horizontal nystagmus during head turning in the supine position.[ncbi.nlm.nih.gov]

  • Central Positional Vertigo

    The second case had very weak apogeotropic nystagmus with torsional and horizontal components in a head-hanging-left position.[jstage.jst.go.jp] horizontal direction-changing geotropic positional nystagmus (mimicking horizontal canal canalolithiasis), and 1 presented with mixed torsional and vertical nystagmus during[stroke.ahajournals.org] The amplitude of the nystagmus may vary in different positions of gaze. [10, 11] Horizontal nystagmus Horizontal nystagmus is a well-recognized finding in patients with a[emedicine.medscape.com]

  • Benign Paroxysmal Positional Vertigo

    The benign paroxysmal positional vertigo of the horizontal semicircular canal is manifested with either geotropic or apogeotropic horizontal nystagmus.[ncbi.nlm.nih.gov] Upon admission, the patient had a third-degree horizontal nystagmus beating to the right, after beating towards the left ear a few hours earlier.[ncbi.nlm.nih.gov] During the physical exam the the patient reports an episode of vertigo after transitioning from sitting to supine and horizontal nystagmus is concurrently noted.[medbullets.com]

  • Spasmus Nutans

    Abstract Spasmus nutans occurs in early childhood and consists of a triad of symptoms as follows: small-amplitude, rapid, horizontal nystagmus in one or both eyes asymmetrically[ncbi.nlm.nih.gov] Patient has a monocular horizontal nystagmus in the left eye. Hallmark is low amplitude, high frequency oscillations (shown in patient).[kaltura.com] • Spasmus nutans occurs in early childhood and consists of a triad of symptoms as follows: small-amplitude, rapid, horizontal nystagmus in one or both eyes asymmetrically;[jamanetwork.com]

  • Vestibular Neuronitis

    Viral infection is suspected to be the most common cause and symptoms are sudden onset of vertigo, nausea, vomiting, impaired balance and horizontal nystagmus.[ncbi.nlm.nih.gov] nystagmus (3) and an unsteady gait (2) nausea and vomiting are common (3) absent tinnitus or deafness (3) no other neurological symptoms or signs (3).[gpnotebook.co.uk] A common indication is horizontal nystagmus with the fast beat towards the healthy ear Resources Resources Drislane, Frank; Michael Benatar, Bernard Chang, Juan Acosta, Andrew[powerofpain.org]

  • Meniere's Disease

    Periodic alternating nystagmus (PAN) is a spontaneous horizontal nystagmus that reverses direction periodically. PAN has been reported in acquired and congenital forms.[ncbi.nlm.nih.gov] Upon admission, the patient had a third-degree horizontal nystagmus beating to the right, after beating towards the left ear a few hours earlier.[ncbi.nlm.nih.gov] Periodic alternating nystagmus is a rare central nervous system disorder in which the eyes undergo a horizontal jerk nystagmus that periodically reverses direction.[ncbi.nlm.nih.gov]

  • Hyperventilation

    The other 50% either have nothing, or a minor horizontal nystagmus.[dizziness-and-balance.com] Many dizzy people have low-amplitude horizontal nystagmus after vigorous HVT. The timing is similar.[dizziness-and-balance.com] The nystagmus lasts about 15 seconds, and is accompanied by "light headedness". See figure above.[dizziness-and-balance.com]

  • Insomnia

  • Hereditary Nystagmus

    The eyes may move from side to side (horizontal nystagmus), up and down (vertical nystagmus), circular (rotatory nystagmus) or a combination of these.[specsavers.co.nz] Abstract The time of onset of congenital horizontal nystagmus is usually known. We present a group of infants in whom this was determined objectively.[nature.com] Other types of nystagmus: Congenital nystagmus: as already mentioned, it is a horizontal spontaneous nystagmus. It is hereditary and exists from birth.[optometry-today.com]
