The parents and the care givers (therapists and teachers) always know what the child sees but they don't know what they know!

  • Team constellation
  • Glare
  • Adaptation to light
  • vision and fixation-following behaviour
  • Communication/interaction
  • Position/site of the body
  • When to assess
  • vestibularis/motor stimulation
  • Level of understanding
  • Correction

Observation of Behaviour

  • Does the person have eye contact with you
  • do you get a smile as answer to eye contact
  • How big is the visual sphere of interest
  • What objects did the person look at
  • How small are the objects the person can look at
  • Did the person take up object for 'looking closely'
  • Did the person prefer colour information
  • Did the person notice object/persons only to the right or to the left
  • Did the person have glare problems
  • Did the person's behaviour change in darkness
  • Did the person prefer to hold the head in some position or did he turn the eyes in some special position when looking
  • Did the person have hand-eye coordination, foot-eye coordination
