5 Possible Causes for Altered Horizontal Eye Movements

  • Nystagmus

    Note the marked mostly horizontal (with some oblique movements) tremor of the head. This rendered the interpretation of the eye movements extremely difficult.[frontiersin.org] The patient was unable to abate the head tremor or alter the amplitude of these movements to command, but instead the tremor became more marked when trying to restrain the[frontiersin.org]

  • Mal de Débarquement

    They also had horizontal nystagmus. The alteration in the eye movements indicated that the vestibulo-ocular reflex (VOR) had been maladapted.[doi.org]

  • Oculomotor Apraxia

    When performed, EOG recordings of all horizontal and vertical saccadic eye movements were severely altered whatever the age of the patient.[ncbi.nlm.nih.gov] It confirms that the control of saccadic eye movements is still altered in adults in both directions horizontal and vertical that were never reported.[ncbi.nlm.nih.gov]

  • Horizontal Gaze Palsy with Progressive Scoliosis

    The study of conditions affecting horizontal eye movement has helped elucidate the causes of horizontal gaze palsy seen in HGPPS.[hippokratia.gr] It is thought that the altered medullary and pontine morphologies observed in HGPPS patients may be a result of failed decussation of corticospinal and dorsal column/medial[hippokratia.gr]

  • Infantile Periodic Alternating Nystagmus

    There are other similar alterations in periodic eye movements (saccadic oscillations) such as opsoclonus or ocular flutter.[englishgratis.com] Note the marked mostly horizontal (with some oblique movements) tremor of the head. This rendered the interpretation of the eye movements extremely difficult.[ncbi.nlm.nih.gov] Nystagmus may occur in the vertical or horizontal directions, and also in a semicircular movement, and thus are called downbeat nystagmus, upbeat nystagmus, seesaw nystagmus[englishgratis.com]
