Figure 4.
Findings of flash electroretinography (FERG). Bar plots show no significant difference of FERG amplitude (A) and latency (B) recorded 1 week after intravitreal injection of self-complementary adeno-associated virus type 2 (scAAV2)–chicken β-actin(CBA)–green fluorescent protein (GFP) (right eye) and scAAV2-CBA-ND4 (left eye) (group 1) (P>.05, paired t test). Similarly, there was no significant difference of the FERG amplitude (C) and latency (D) 1 week after intravitreal injection of single-stranded (ss) AAV2-CBA-ND4 (right eye) and scAAV2-CBA-GFP (left eye) (group 2) (P>.05, paired t test).
