Flashcards in Intro to Neuro-optometric Rehab and VT Deck (17):

what is neuroplasticity

an ongoing reorganization of the functional cortical map. Changed scientific thinking from a definite “Critical Period” to neuroplastic learning at all ages= Hebbian learning


what is the underlying trigger for the reorganization in neuroplasticity

synaptic plasticity


what 3 things help influence synaptic plasticity (vision therapy)

specific experiences, repetition, and feedback = vision therapy


what does the vision therapy experience help create

a synaptic learning experience that involves active participation


what are examples of feedback

anti-suppression techniques, physiological diplopia, fixator etc.


how does vision therapy have repetition

it has several procedures that reinforce the same concept (office and at home)


what are 6 ways to create new synapses

active participation and experience, feedback/motivation, repetition, motor match to a sensory mismatch, multi-sensory stimuli, and problem solving tasks


what is the definition of Skeffingtons 4 circles

vision is learned so vision is trained --> demonstrates overlapping and interweaving of "visual systems" (Emergent is vision)


what are the 4 Skeffington circles

1. centering (where is it in space)
2. identification (what is it)
3. speech/auditory (communicating the visual information)
4. Anti-gravity/support (where am I in space/vestibular ocular reflex)


what are some ways vision therapy uses treatment sequences

sequencing monocular and bi-ocular phases (start monocular -> bi-ocular), binocular phase with anti- suppression, length of treatment, and treatment plan for specific disorders


what system is for peripheral or side vision

magno awareness (ambient system)


what system is for central/detail orientation

parvo awareness


which system, magno or parvo, is more susceptible to damage in brain injuries



what is the goal of vision therapy

to remediate an existing vision disorder and/or enhance visual function = AUTOMATICITY


when is vision therapy performed

recommended when case analysis and evaluation indicate that lens application alone is insufficient to provide optimal visual function


what is the concept of loading

adding elements to increase difficulty of task - metronome, balance board, lenses/prisms, decrease print size


what are 3 optometric organizations in the vision therapy field

optometric extension program (OEP), college of optometrists in vision development (COVD) and neuro-optometric rehabilitation association (NORA)
