Retrobulbar lidocaine reversibly reduces Pattern Electroretinogram (PERG). (A) PERG waveforms in DBA/2J mice before and at different times after injection. Continuous black lines represent the grand-average waveform of all mice tested, and colored dashed lines represent the superior (red) and inferior (green) 95% confidence interval of the mean; (B) Peak-to-trough PERG amplitude decreases by about 60% one hour after lidocaine but recovers baseline values one day after injection. The effect is repeatable after four injections four days apart. Bars represent the mean ± SEM (N = 5).
