  1. What are the 4 levels of sensorimotor fusion?
    • 1: simultaneous perception
    • 2: superimposition
    • 3: flat fusion
    • 4: stereopsis
  2. Simultaneous perception?
    • diplopia
    • seeing 2 similar targets
    • non corr. pts
  3. Superimposition?
    • confusion
    • 2 diff targets not integrated
  4. Flat fusion
    • fusion with no depth
    • will see pink light with red lens test
    • 2 similar targets integrated
  5. Stereopsis
    • points of the target are laterally displaced
    • fusion with float
  6. Central suppression?
    <5deg from fovea
  7. Peripheral suppression?
    >5deg from fovea
  8. 3 components of visual efficiency?
    • 1. Quality: Fixation maintenance (viscuoscopy) and saccades/pursuits
    • 2. Accommodation: amp, facility, accuracy
    • 3. Vergence: jumps/smooth and gross convergence
