  1. Small saccades and no smooth pursuits?
    pathological
  2. What are two problems with saccades
    overshooting (less common) and undershooting (more common- slight)
  3. what are some symptoms associated with poor ocular motility
    • Loses place when reading
    • Skips words when reading
    • Reads same line twice or skips a line
    • Excessive head movement
    • Poor ability to copy from blackboard
    • Sports - catching ball, tennis
    • Repeats letters within words
    • Misaligns columns of numbers
    • Close working distance
  4. Do you observe the quickness of a saccade?
    not so much the speed but the reaction time
  5. Head movements with relation to the saccades?
    • try to get px to keep head still
    • poke forehead
  6. how may poor ocular motility be managed?
    vision training and specs
  7. How does vision training for poor ocular motility work?
    eye exercises- setting up conditions that require the correct use of eyes to perform that visual task properly
  8. What are the order of the deficits of poor ocular motility attacked?
    • Fixation
    • Pursuits
    • Saccades
    • Accommodation
    • Vergence
    • (allow overlap)
  9. What is vision therapy
    • vision tasks that are able to be transfered to real life
    • the task is done while the px is being distracted e.g. talking 
    • it must be maintained to avoid regression
  10. What is the order of treatment for pursuits?
    • Attention to stationary targets- make sure they can fixate first
    • Volitional movement control- look up/down
    • Eye-hand support- read using the hand to guide the eyes
    • Small, then large excursions
    • Slow, then fast excursions
    • Equality of monocular activity- start mono if there is a mono problem then do with BE open
  11. What is the general order of treatment for saccades?
    • Attention to stationary targets- make sure they can fixate first
    • Volitional movement control- look up/down
    • Eye-hand support- read using the hand to guide the eyes
    • Small, then large excursions
    • Slow, then fast excursions
    • Equality of monocular activity- start mono if there is a mono problem then do with BE open
    • After good monocular ductions,
    • good binocular versions
    • Increased cognitive demand
    • Sitting to standing (?)
    • Increase vergence demand
    • Sight sound integration
    • Left to right sequence
    • Cognitive demands
    • Increase vergence demand
    • Throughout
    •       Eliminate head movement
    •       Eliminate undershoots, overshoots and
    • regressions.
  12. What is the basic principle of vision training?
    visions is not innate and therefore it can be trained and learned
