Basic Neuro-optometric techniques Flashcards
what 3 things is the neuro-optometric VT experience based on
the concepts of neuroplasticity, “synaptic learning experience” and active participation
what is ocular pursuit training
develop ocular motor control and ability to sustain visual attention- require sustained fixation of a moving target
what are 2 tests for pursuit training
visual tracing test (basic) and Groffman eye trails test
what do you do to a task to build automaticity
vary the task demands - used concept of loading
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
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)
what does the opaque lifesaver card test
convergence
what does the clear lifesaver card test
divergence
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)
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
what is the feedback in the brock strings
physiological diplopia
what is the single window aperture testing
convergence
what is the double window aperture testing
divergence
what are the numbers measuring in the vectograms
convergence
what are the letters measuring in the vectograms
divergence
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
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
why would you use bi-nasal tapping on glasses
hemianopsia (only nasal portion of lens with blind spot)
what do the yoked prisms do
shift spatial perception/shift image location, improve balance in midline shift patients
what should end-stage techniques include
accommodative-convergence flexibility
