Figure 1. Electroretinogram (ERG) phenotype of Lrp5^tvrm111B mice. A: ERGs obtained from strobe flash stimuli presented to the dark-adapted eye from representative control (left) and Lrp5^tvrm111B (right) littermates. Scale bars indicate 500 µV and 200 ms. B: ERGs obtained from strobe flash stimuli superimposed against a steady adapting field from representative control (left) and Lrp5^tvrm111B (right) littermates. Values to the left of each pair of waveforms indicate flash strength (log cd sec/m²). Scale bars indicate 200 µV and 200 ms.
