VEP QUICK REFERENCE GUIDE
3
Connect the
electrodes to the
RETeval adapter
cable for DIN
electrodes which
is connected to
the device. The
device will verify
that your electrode
is connected
securely (pic 1),
and that the electrode noise is suciently small enough to
proceed (pic 2). Select “Next”.
1
Ask paent to cover the eye that is not being tested with
their hand or patch the untested eye.
2
Make sure the paent is relaxed and does not tense
any muscles, including doing any talking. Ensure the
surrounding area is quiet and that the paent has no
background noise or access to a phone.
3
Place the eye cup
of the device so
that it rests evenly
over the paent’s
right eye rst, if
doing a bilateral
test. Inform the
paent to focus
on the red light
in the center of
the ganzfeld. Ensure the paents pupil is located within
the green circle shown on the screen. Select “Start test”.
Device will progress through each step.
• TIP: For Td protocols, the whole pupil must be visible to
the operator. The test will not proceed if it is not visible.
Make sure to wait for the blue circle with red crosshatch
to appear over the pupil.

Upon compleon of a step, certain
protocols will allow you to review the
waveform. If you are sased, select
“Next”, or select “Repeat” to repeat
the step again. You should repeat the
test at least two or three mes per
eye prior to moving forward.
5. BEGIN TEST
5
Aer all steps
are completed,
the device will
automacally
save the results.
6
You will have the
opon to “Retest”
the paent once
you’ve viewed their
results.
7
Once tesng is completed, disconnect the RETeval DIN
Adapter Cable from the electrodes. Remove electrodes and
clean any leover gel from the paent and electrodes.
1
Connect the RETeval device’s docking staon to your
computer using the USB cable. Set the RETeval device in
the docking staon. On your computer, the RETeval device
will show similar to an external thumbdrive. To access the
PDF reports, locate the “Reports” folder, which is sorted
by date modied. The PDF report follows the format of
“PaentID_DOB_TimeStamp”.
6. FILE REPORT
1
Cleaning of the eyecup and DIN Adapter cable is
recommended between paent uses. The RETeval device
exterior can be cleaned with either 70 % isopropyl alcohol
or alkyl dimethyl benzyl ammonium chloride.
