For the dark-adapted testing, dark adaption can be done overnight before the test starts or for at least 20 minutes before
testing. Use the red backlight option in
Settings
(see page 6) to start the test with a red screen. Oscillatory potentials are
automatically calculated from the DA 8.0 test, which is the 4
th
step in the protocol.

For testing rats and mice, dimmer stimuli are typically used (Dembinska et al. 2001, Dembinska et al. 2002, Polosa et al. 2019).
Photopic and scotopic tests can be performed separately or together depending on the study design, there are separate
protocols for measuring just the animal’s right or left eye.

Overnight dark-adaptation is recommended in rodents. Oscillatory potentials are automatically calculated from the DA 8.0
test, which is the 3rd step in the protocol.
