Design outcomes

Primary

Measure	Time frame
Eye movements: - Latency (defined as the time between the display of the visual stimulus and the start of the eye movement (in milliseconds)) - Eye velocity (degrees of arc per second) - Gaze direction accuracy or "gain" (degrees of arc) - Number of errors in the tasks performed Eye-hand coordination: - Response time (defined as the time between the saccade and the start of the hand movement (in milliseconds)) - Duration of the movement itself (in milliseconds) - Distance traveled from start position to the target (in centimeters) - Peak velocity of hand movement (meters per second) - Number of errors in the tasks performed. All outcome measurements will be compared with the results of the healthy subjects. Also, the results between the groups themselves will be compared.	—
