Saccades are recorded at preset time intervals during the dark phase and thereafter during the light phase.
The test is available on the MonPackONE and MonColor systems.
These systems include a built-in video monitoring device which is esssential for monitoring the subject's eye movements and opening of the eyes.
The program measures the amplitude of each saccade and then determines:
• the minimum amplitude during the dark phase (dark through),
• the maximum amplitude during the light phase (light peak)
• and their ratio (Arden ration).
