  1. Q: What are the four basic models of vision care?
    • Medical
    • Optical
    • Functional
    • Behavioral
  2. Q: what are skeffington's four circles?
    • Antigravity
    • Centering
    • Identification
    • Speech-auditory
    • = vision (where all 4 meet) - higher order processing
  3. Q: what is antigravity
    Space localization / orientation
  4. Q: what is centering
    • Determine distance from body based on convergence
    • Cyclopean eye
  5. Q: what is identification?
    • Identify dominant features of objects
    • Requires accommodative response
  6. Q: what is speech-auditory?
    • Required to name objects seen
    • Stored in memory for later recall
  7. Q: what npd manifestations are usually symptomatic?
    Flight (sympathetic) response
  8. Q: what is sheards criterion?
    Compensating vergence should be 2x the phoria amount
  9. Q: what is percival's criterion?
    Pt's phoria should be in the middle 1/3 of fusional vergence range
  10. Q: what is fixation disparity?
    • Small misalignments of eyes are measured in minutes of arc
    • Can generate forced vergence
    • Measured under true binocular conditions
    • Best way to prescribe prism
  11. Q: what are the advantages to fixation disparity?
    • True binocular conditions
    • Best way to determine Rxed prism
  12. Q: what are the disadvantages of fixation disparity?
    Only tests FD, doesn't take motility into consideration
  13. Q: what tests are used for NFV
    • Smooth vergence
    • Step vergence
    • Vergence facility (BI prism)
    • PRA
    • Binocular accommodative facility (minus lenses)
    • Mem
    • BCC
  14. Q: what tests are used for accommodative system?
    • Sheards
    • Monocular flippers
    • MEM
    • BCC
    • NRA / PRA
  15. Q: what are the tests for motor alignment?
    • CT
    • Von-graph (step vergence)
    • FD
    • AC/A
  16. Q: up until what age are you able to perform o-scope and ret while they are sleeping
  17. Q: after what age could you start to use phoropter on children?
    3 yrs
  18. Q: when can you expect reliable responses from subjective tests?
    4 yo +
  19. Q: what age range should you be able to perform phorometry?
    4 yo+
  20. Q: at what point should you expect reliance on subjective test to be adult-level?
  21. Q: what is the exam schedule for kids
    • 1st exam @ 6mo then yearly or every 2 years
    • Full assessment before entering kindergarden
  22. Q what do duction, versions, and vergence mean?
    • Duction: one eye movement
    • Versions: two eyes move same direction
    • Vergence: two eyes move opposite direction
  23. Q: on which eye do you use prisms on krimsky tests
    On fixating eye
  24. Q: what SA test is required for truck drivers?
    Random dot E
  25. Q: what color test is required for military, firefighters, and policemen?
    Farnsworth D-15
  26. Q: what type of fusion does worth 4 dot test?
    Flat fusion
