Figure 4. Retinal function measured by electroretinography (ERG) in rats fed for three weeks under cyclic dim (50 lx) light. Scotopic ERG-A (absolute value) and B wave amplitude were analyzed from the rats fed for three weeks with CAPE and reared under dim cyclic light. CAPE-A: A wave from rats fed by CAPE diet; CONT-A: A wave from rats fed by control diet; CAPE-B: B wave from rats fed by CAPE diet; and CONT-B: B wave from rats fed by control diet. (n=8/ group; *: p<0.01, **: p<0.001, with the Student t test).
