  • 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] 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] Three patients developed a spontaneous "irritative" nystagmus during the early post-treatment period.[ncbi.nlm.nih.gov]

  • Primary Progressive Multiple Sclerosis

    Double vision or eye tremor ( nystagmus ) may result from involvement of the nerve pathways controlling movement of the eye muscles.[medical-dictionary.thefreedictionary.com] […] muscle spasms, or difficulty in moving; difficulties with coordination and balance (ataxia); problems in speech (dysarthria) or swallowing (dysphagia), visual problems (nystagmus[disabled-world.com] […] pronounced reflexes, muscle spasms, or difficulty in moving; difficulties with coordination and balance ( ataxia ); problems with speech or swallowing, visual problems ( nystagmus[en.wikipedia.org]

  • Acoustic Neuroma

    The clinical signs may be characterized as: a) progressive unilateral or asymmetrical sensorineural dysacusis, b) intermittent hearing loss, c) tinnitus and sensation of fullness[scielo.br] Hyperventilation for 30 seconds provoked an ipsilateral beating nystagmus and reproduced the vertiginous sensation in both subjects.[ncbi.nlm.nih.gov] […] neuroma (mainly intracanalicular type) were studied with a full audio-vestibular test battery (pure tone and speech audiometry, caloric bithermal test, vibration-induced nystagmus[ncbi.nlm.nih.gov]

  • Labyrinthine Concussion

    Slight nystagmus on fistula test is indicative of oval or round window fistulae while strong nystagmus can indicate superior semicircular canal dehiscence.[symptoma.com] Nystagmus is typically horizontal or torsional and direction-fixed.[journals.lww.com] Nystagmus and alteration in hearing are a prerequisite to label the condition as labyrinthine concussion.[symptoma.com]

  • Labyrinthine Fistula

    The postoperative vertigo with nystagmus is more frequent in larger fistulas.[ingentaconnect.com] In the remaining 6 ears, pressure loading of the ear canal induced the sensation of vertigo without accompanying nystagmus.[ncbi.nlm.nih.gov] Stimulation of the labyrinth results in nystagmus and vertigo.[aippg.net]

    Central vertigo can be characterized by purely torsional, pendular, or vertical nystagmus, and bidirectional gaze-evoked nystagmus. 2, 4, 5 In addition, spontaneous nystagmus[neurology.org] Oroscopic, rhinoscopic, and otoscopic examinations were normal along with a positive Romberg test at the right and nystagmus was absent.[arquivosdeorl.org.br] In the author's experience, these patients often exhibit rebound nystagmus, which is a variant of gaze-evoked nystagmus.[dizziness-and-balance.com]
