3.4.3 Saccade test
During the saccade test the patient’s eyes have to follow randomly moving target jumping from side to side.
The default Saccade test will have the target jump horizontally, but the test has optional vertical and
combined (a mix of horizontal and vertical positions) subtests available. The patient must fixate on the target
and then move to the next target with fast eye movements (saccades). Ideally, the saccades should consist
of one single fast movement that leads to re-fixation on the next target. By default both eyes are displayed
on the same waveform graph and analysis graphs to show if the patient exhibits any disconjugate eye
movements. The test settings has the option to split the eyes into separate graphs if needed to better
ascertain an eye’s specific response.

The saccades are automatically analyzed as the test is performed, and the results are displayed for latency,
velocity and accuracy for each saccade. Each eye will be analyzed separately with results plotted for each
eye (default) or for a selected eye (right or left).
