Flashcards in Basic Neuro-optometric techniques Deck (20):
1

what 3 things is the neuro-optometric VT experience based on

the concepts of neuroplasticity, "synaptic learning experience" and active participation

2

what is ocular pursuit training

develop ocular motor control and ability to sustain visual attention- require sustained fixation of a moving target

3

what are 2 tests for pursuit training

visual tracing test (basic) and Groffman eye trails test

4

what do you do to a task to build automaticity

vary the task demands - used concept of loading

5

what are 3 techniques to improve fixation, pursuits and eye tracking (station 1 in lab)

keystone visual skills, monocular pointer-in-the-tube (straw) and monocular timed alphabet tracking

6

what are 4 techniques to improve accommodation and binocular awareness, improve saccades (station 2 in lab)

binocular accommodative facility (flipper), opaque/clear lifesaver cards, opaque eccentric circles, and underlined Developmental eye movements test (DEM)

7

what does the opaque lifesaver card test

convergence

8

what does the clear lifesaver card test

divergence

9

how do you perform the Developmental eye movements test (DEM)

patient call out series of numbers/letters that are underlined as quickly as possible (can use metronome for loading)

10

what are 4 techniques to improve eye teaming, binocularity, central/peripheral awareness (station 3 in lab)

4 hart charts (far), brock strings, aperture ruler trainers, and vectograms

11

what is the feedback in the brock strings

physiological diplopia

12

what is the single window aperture testing

convergence

13

what is the double window aperture testing

divergence

14

what are the numbers measuring in the vectograms

convergence

15

what are the letters measuring in the vectograms

divergence

16

what 5 techniques are for peripheral vision awareness development, emphasis on magno/ambient processing (station 4 in lab)

MacDonald and alphabet field cards, bi-nasal taping on glasses, fresnel prism, yoked prism, and eye trails

17

what are the MacDonald and alphabet field cards

timed with no head movement (letters are larger in periphery and smaller in center) - tell patient if there eye deviates from center dot

18

why would you use bi-nasal tapping on glasses

hemianopsia (only nasal portion of lens with blind spot)

19

what do the yoked prisms do

shift spatial perception/shift image location, improve balance in midline shift patients

20

what should end-stage techniques include

accommodative-convergence flexibility
