Figure 1. Dark-adapted ERG a-wave (photoreceptoral) and b-wave (post-photoreceptoral) elicited by step-wise increases in stimulus strength.

Figure 1

(A) Representative traces corresponding to responses elicited by a stimulus intensity of 1.36 log cds/m2; (B) a-wave, and (C) b-wave amplitudes measured in control and IUGR offspring at 2 and 14 months of age. Adjacent bar graphs depict corresponding peak amplitudes. **P<0.01 compared to controls at the same age.
