The test image (optotype) that the patient is presently seeing is shown to
you in the test image display
(fig. 10-2, page 29, item 2) Here, you have
to mark the individual test results so that the examination can be
subsequently evaluated. Here, you can mark which optotypes the patient
has recognised or not recognised. The following shows you how to mark
the results.

Click on the optotype if the patient has recognised it.
The recognised optotype is marked with a green tick.
If the patient does not recognise the optotype, click twice on the
optotype.
10.1.3 Present the Next Optotype
After you have marked the results, you must present another optotype to
the patient. A number beside the optotype (here: 1) indicates the first
position of the optotype. You can present 5 different Landolt ring
positions per contrast level to the patient, see
fig. 10-2, page 29, item 2 .
The visual requirement is deemed met when the patient has recognised at
least 3 of 5 positions of the Landolt ring (60% criterion).
