be dark adapted.
2
The test should take place in a dimly lit room.
3
Clean the forehead in the middle and one earlobe using
NuPrep skin preparaon gel.
4
Idenfy the Oz posion, part the paents hair and clean
with a skin cleanser pad.
• For an adult with a normal-sized head, the Oz is
located about 2.5 cm above the inion on the midline.
• For children the Oz point is located on the midline,
10 % of the distance above the inion towards the nasion.
3. PATIENT PREPARATION
4. CONNECT ELECTRODES
1
Connect the electrode as follows:
a
Acve recording electrode
Place the recording electrode to the idened Oz
posion (posive).
• In case of a gold cup electrode, apply electrode
conducve adhesive gel inside the gold cup.
• Use this gel to separate the hair away from the
recording site; hair touching the gold cup electrode
adds noise to the signal.
b
Reference electrode
Place reference electrode on the forehead (usually an
ECG electrode with a ground reference lead aached).
c
Ground electrode
Apply electrode gel to the ear clip and place it on the
earlobe.
2
The screen will present opons prior to connecng
the electrodes to the RETeval adapter cable for DIN
electrodes. “Cancel” will cancel the enre test. “Done OD/
OS” will skip all tests of the specied eye. “Skip” allows the
user to skip current test step.
The electrodes and supplies required for VEP tesng are not included with
the RETeval
®
device package. Please order the RETeval Flash VEP Electrode
& supply kit from your distributor or from LKC direct store.lkc.com.
