  • Nystagmus, forms of nystagmus

    Nystagmus (nystagmus) is a spontaneous oscillatory eye movements.


    The following types of nystagmus:

    • pendulum,
    • clonic
      (Tolchkoobrazny)
    • mixed.

    Towards:

    • horizontal,
    • vertical, rotatory,
    • diagonal (direction judged by
      rapid oscillation phase).

    In the span:

    • large-,
    • medium,
    • melkorazmashisty.

    What is nystagmus, nystagmus form
    Frequency
    oscillating movements can exceed several hundred per minute.
    Acquired nystagmus is always accompanied by blurred vision
    perceptions (although central vision may be high), and
    dizziness, and congenital nystagmus causes of vertigo.

    Nystagmus as paralysis, in a central or inherently
    Local genesis. The development of nystagmus can be caused by lesions
    cerebellum, bridge, medulla, the second frontal gyrus,
    roof plate (quadrigemina), pituitary and some other departments
    of the brain as a result of inflammatory and neoplastic processes or
    vascular disorders. On the other hand, it may arise
    low vision in both eyes due to the haze, optical anomalies
    media change and choroid, retina and optic nerve.

    When lesions of the central parts of the nervous system arise
    Cortical, vestibular, hysterical and
    other types of nystagmus. Damage to the peripheral visual
    or acoustic analyzer cause visual and labyrinthine nystagmus.

    There is also a physiological nystagmus, which include such
    it views as optokinetic, labyrinthine and nistagmoidnye
    twitching (in extreme leads the eye). As it is known, on the basis of
    optokinetic nystagmus can check visual acuity in children. Study labyrinth nystagmus plays a big role,
    for example, in the assessment of the functional state of the vestibular apparatus in
    astronauts.



    nystagmus Treatment

    Treatment of nystagmus is difficult and often unsuccessful. All
    efforts directed at eliminating a common cause, it caused that
    is the lot of many experts. All therapeutic measures,
    allowing to improve visual acuity (amblyopia treatment, correction
    eyeglasses, reflexology, cataract extraction, keratoplasty and
    et al.), as well as reducing muscle tone may lead to
    reduction of nystagmus.

    Surgery on the muscles gives the effect of basically only in the horizontal nystagmus.
