Electroretinograms are normal in AhR−/− mice.

<p>(A) Representative scotopic ERG at different light intensities (from −2 to −0.49 log cd.s/m²) in both AhR+/+ and AhR−/− mice. Quantifications of a-Wave and b-Wave amplitudes are represented in the lower panel. (B) Representative photopic ERG. The photopic response is obtained using a flash intensity to −0.49 log cd.s/m² on light-adapted mice and measured for both mice. There are no significant differences between both genotypes in scotopic and photopic ERG. Blue lines correspond to the AhR+/+ mice, and red lines correspond to the AhR−/− mice.
