VT for Eye Movement Disorders: Saccades Flashcards
What are the fail criteria for the NSUCO and the Visagraph/Readalyzer?
Results below expected performance for the patient’s age.
What are the fail criteria for the DEM?
Below the 16th percentile in Ratio or Error scores. (It is suggested that this be with no symptoms, and below the 32nd percentile with symptoms.)
The primary goals and objectives of VT for oculomotor dysfunctions is to normalize (or at least maximize) eye movement skill, and to eliminate (or at least reduce) symptoms related to eye movement dysfunction. What is the typical length of therapy?
Anywhere from 8 to 24 sessions
During VT, accuracy is the first priority, followed by speed, then by automaticity and transfer of skill. Begin with ____(gross/fine) movements at _____ (far/near), then proceed to ____(gross/fine) movements at _____ (far/near).
Begin with gross movements at far, then proceed to fine movements at near.
When should you use a metronome for a saccade VT task?
If the task is predictable, but only once accuracy has been achieved.
The following are phases of saccade training as presented by Dr. Erickson. What sort of saccades are being developed in each phase?
Phase Ia:
Phase Ib:
Phase II:
Phase III:
Phase Ia: gross saccades (predictable)
Phase Ib: gross saccades (less predictable)
Phase II: fine saccades (predicable patterns)
Phase III: reading-pattern saccades
Phase Ia of saccadic therapy trains predictable gross saccades. The following are tasks that are used during this phase. Which of these involves a chart that can be either used whole or cut into various configurations?
Corner/Doorway saccades Hart chart variations Alphabet pencil saccades Sequential fixator Meter stick saccades
Hart chart variations
Phase Ia of saccadic therapy trains predictable gross saccades. The following are tasks that are used during this phase. Which of these involves feedback via an after-image flash?
Corner/Doorway saccades Hart chart variations Alphabet pencil saccades Sequential fixator Meter stick saccades
Corner/doorway saccades (try to line up the after-image with the corner of the door); note that you can use this during a 4 corner saccadic task with a Hart chart too.
Phase Ia of saccadic therapy trains predictable gross saccades. The following are tasks that are used during this phase. Which of these involves a transparent sheet and predicable targets?
Corner/Doorway saccades Hart chart variations Alphabet pencil saccades Sequential fixator Meter stick saccades
Sequential fixator
Phase Ib of saccadic therapy trains less predictable gross saccades. The following are tasks that are used during this phase. Which of these involves motor response to light and gives feedback with light and sound? How is this training type scored?
Laser spelling Continuous motion worksheet Wayne Saccadic Fixator (or similar) Saccadic Fixations Workbook Series Wayne Directional Sequencer Sequential fixator Computer VT programs
The Wayne Saccadic Fixator–light come on along certain points of the instrument, and the patient’s task is to touch the light. The scoring system can either be based on speed (self-paced) or on number of hits (instrument-paced).
The Wayne Directional Sequencer is very similar in function, but has the patient follow a series of arrows in deciding which button to push.
Phase Ib of saccadic therapy trains less predictable gross saccades. The following are tasks that are used during this phase. Which of these is similar to a sequential fixator, but includes motor feedback via a pencil or a laser?
Laser spelling Continuous motion worksheet Wayne Saccadic Fixator (or similar) Saccadic Fixations Workbook Series Wayne Directional Sequencer Sequential fixator Computer VT programs
Continuous motion worksheet or laser spelling (both involve searching saccades and a pencil or laser to find letters or numbers in a certain sequence among randomized letters or numbers)
Phase II of saccadic therapy trains predictable fine saccades. Many of these activities use the Hart chart similar to phase Ia, but now at a finer demand.

Phase III of saccadic therapy trains reading-type saccades. The following are tasks that are used during this phase. Which of these involves a paragraph of nonsense words?
X's and O's Word finds Moving window programs Michigan (Ann Arbor) Symbol counting Dotting O's
Michigan (Ann Arbor)–the task is to find the letters of alphabet sequentially as you read through the paragraph of nonsense words.
Phase III of saccadic therapy trains reading-type saccades. The following are tasks that are used during this phase. Which of these controls the exposure of words during reading (i.e., exposes only a few words at a time, in a continuous manner)?
X's and O's Word finds Moving window programs Michigan (Ann Arbor) Symbol counting Dotting O's
Moving window
