4.4.2 1st & 2nd Pupil
At the beginning of the evaluation, the system automatically searches for the pupil centers . You should
check this preselection and edit it if necessary.
To do this, you can use the zoom function and move the selection crosses or use the displayed arrow
keys. The selection markers can also be moved using the [Arrow] key on the keyboard. Use the [Tab] key to jump
back and forth between the selection markers for the left and right pupil.
