To select an existing patient from the list, click on the
PATIENT LIST
button: the complete list of
stored patients will show up (see Figure 6).
The following mechanisms are available to find a specific patient:
scroll the list by dragging the screen up or down;
sort the list by one of the available field (the list can be sorted by last name, age or date of
last visit) by clicking on the corresponding arrows (
for descending,
for ascending)
located at the header of the list (by default patients are sorted by their numeric ID, in
ascending order);
search for a specific patient by typing the initials of the last name or first name in the
search
box.

9.3 Starting the image acquisition process
Whether a new patient has been created or an existing one selected or none of the above
(anonymous), it is possible to start the image acquisition process.
Before proceeding, be sure that the patient received complete explanations concerning the test
and what she/he is required to do, as explained at par.5.1.
Then proceed as follows:
a. Select OU to acquire images from both eyes (default), OD for the right eye only and OS for
the left eye only;
b. Select SINGLE FIELD to acquire one 45° image of the retina (default) or MULTI FIELD to
acquire multiple fields at 45° per photo. See par. 14.1 for details on how to configure the
fields acquired in each of the above two options; you can also select ANTERIOR EYE to
acquire the external part of the eye (useful to prove the presence of cataract in case of
impossibility to acquire the retina) or STEREO to acquire a couple of Central Nasal field
images with two different head displacement to produce a Stereoscopic vision of the optic
disc (see details below);
c. Position the patient on the chin rest and head rest and use the CHINREST UP and
CHINREST DOWN buttons to adjust the chin rest position, if needed. When the
AUTOMATIC CHIN REST flag is selected from the settings menu (see par. 14), the chin
rest is automatically adapted to the patient head characteristics.
d. Press the START button to start the acquisition procedure.
