Nystagmus

• Nystagmus is a repetitive, rhythmical and
  involuntary movement of the eyes. It generally
  happens from side to side, but at times it also
  happens as up and down or in a circular motion.
  Both of the eyes can move together or
  independently of each other. A person suffering
  with nystagmus has no control over this movement
  of the eyes.

What causes Nystagmus?

• Early onset nystagmus will appear in very young
  babies. It can also be called as congenital
  nystagmus. Acquired nystagmus is found when the
  condition is seen later in childhood.The
  condition can be caused by a developmental
  problem of the brain or eye, or the pathway
  between the two. At times, the condition can be
  caused by a stroke or head injury.The majority
  of children with the condition do not have any
  other health problems. When the cause of the
  condition is unknown, it is called idiopathic.
  Some type of nystagmus can be inherited.

How nystagmus is normally diagnosed?

• The condition can be easily diagnosed by
  performing various eye tests. These will consist
  of a normal sight test and monitoring their eye
  movements.Nystagmus is defined according to the
  direction of movement of the eyes, how far they
  move and how often. Both eyes can move together
  or independently of each other.

Signs Symptoms of Nystagmus

• The most common indication that a child has
  nystagmus is their eye or eyes will be moving
  randomly. The child may not be aware of
  this.Children suffering with nystagmus mostly
  have poorer vision and face problems with
  balance. They will also find it more difficult to
  follow fast movements.

How nystagmus is normally treated?

• There is no cure for nystagmus.Vision
  problems, like long or short sightedness are
  common in people with nystagmus. Glasses will not
  treat the condition, but can help with reduced
  vision.Large print books can help and will be
  especially useful for children learning to read.
  Extra time in school tests may be needed as
  reading the questions may take a little
  longer.There is often a null point where the
  eye movement is reduced. At time, this can
  involve by holding the head at an awkward angle,
  but it will help improve vision. Sometimes the
  eyes can be operated upon to reduce the awkward
  head posture (angle).

• There are some of the authorities who advise
  operating on specific types of nystagmus to
  improve the quality of vision. Specific strict
  criteria can be met by an eye movement recording
  before such procedures can be undertaken.
