Oculomotor rehabilitation in acquired brain injury: A case series¹

Simulated reading patterns. (A) Multiple-line stimulus pattern. (B) Single-line stimulus pattern.

Fixational eye movements in the stroke patient. Left panels, before training (Pre); right panels, after training (T2). Top graphs, horizontal and vertical eye positions as functions of time; middle graphs, 2-dimensional plot of horizontal and vertical fixational eye position scatter/error (ie, the fovea projected into visual space relative to the reference fixation point [0,0]); and bottom graphs, mean radial fixation error. NOTE: 1200 samples from an artifact-free, 10-second portion of the time/eye position traces were used for the 3 fixational error analyses.

Predictable horizontal saccades (20°) for the left eye (XL) before (right) and after (left) all training in the stroke subject. Leftward is left, rightward is right, time in seconds during the trial is specified to the left of the vertical line, and onset of step target changes is indicated by numbered markers to the right of the vertical line.

Simulated reading mean saccade frequency ratio before (Pre) and after (T2) training for multiple-line (ML) and single-line (SL) conditions in the stroke patient.

Reading eye movements for adult level 10 paragraphs before (top) and after (bottom) training in the stroke subject with right hemianopia. Up is right, and down is left. Time periods for both eye movement traces are the same.

Fixational eye movements in the patient with TBI. Left panels, before training (Pre); right panels, after training (T2). Top graphs, horizontal and vertical eye positions as functions of time; middle graphs, 2-dimensional plot of horizontal and vertical fixational eye position scatter/error (ie, the fovea projected into visual space relative to the reference fixation point [0,0]); and bottom graphs, mean radial fixation error. NOTE: 1200 samples from an artifact-free, 10-second-portion of the above time/eye position traces were used for the 3 fixational error analyses.

Predictable horizontal saccades (20°) for the left eye (XL) before (right) and after (left) all training in the subject with TBI. Leftward is left, rightward is right, time in seconds during the trial is specified to the left of the vertical line, and onset of step target changes are indicated by numbered markers to the right of the vertical line.

Simulated reading mean saccade frequency ratio before (Pre) and after (T2) training for multiple-line and single-line conditions in the patient with TBI.

Reading eye movements for adult level 10 paragraphs before (top) and after (bottom) training in the subject with TBI. Up is right, and down is left. Time periods for both eye movement traces are the same.
