Photopic ERG refers to vision under which lighting condition?

Explanation:
Photopic ERG measures cone-driven vision, which operates in bright lighting. Cones support high-acuity, color vision when there is plenty of light, and the photopic ERG specifically captures the retina’s electrical response from these cone pathways under those bright conditions. In contrast, rods drive vision in dim or low-light conditions and are largely saturated under bright illumination, so they don’t contribute to the photopic response. Therefore, photopic ERG refers to vision under bright light.
