❖ Give the patient detailed information about the device operation before
placing the patient on the device.
❖ The configuration of many fields ends in different portions of the retina being
acquired. Such fields can be stitched together using the Mosaic feature
(available under license). See §33 11.5.
❖ The live view on the left is used to visualize the position of the patient’s pupil
from the frontal lens. To ensure the correctness and speed of image
acquisitions the pupil shall fall in the area delimited by yellow bands.
When the patient is ready and the acquisition is configured, press the START EXAM button to begin
the image acquisition procedure.
