Early retinal function alterations in BN-J rats. ERG was performed on 3-week-old BN-H and BN-J rats. Although global ERG responses show a trend but not significant reduction in a-wave amplitude (A), the b-wave amplitude is significantly decreased (B), suggesting postreceptoral disturbance of the visual signal in the inner retina. Scotopic ERG shows a significant reduction in a-wave (C) and b-wave (D) amplitudes from 0.1 to 3 cd · s/m2, suggesting intense rod visual pathway dysfunction. n = 5 rats for BN-H and n = 4 for BN-J. *p < 0.05.
