Figure 7. Oscillogram of pattern-reversal visual evoked potential (PR-VEP) and P₁₀₀ amplitude in PR-VEP. A: Normal control group (n=16); B: strabismic amblyopia group (n=17); C: anisometropic amblyopia group (n=20). D: P₁₀₀ amplitude in PR-VEP. We can see, using high spatial frequency, the reduced amplitudes of anisometropic amblyopia group were more significant than those of the other groups. *means p<0.05, **means p<0.01.
