Figure 5

Raw scotopic ERGs in the different drug injection groups. Representative ERGs recorded after intravitreal injection of DMSO (a), AM251 (b), or AM630 (c). ERG recordings of each treated animal were established by presenting progressively brighter flashes (top to bottom). Horizontal calibration, 20 ms; vertical calibration, 75 μV.
