Ambient lighting alters pattern electroretinogram p50 peak time and spatial sensitivity

HIGHLIGHTS

• What: The photometric measurements demonstrated a 10.4% reduction of stimulus contrast and 8.5 cd.m2 increase in mean stimulus luminance in lights-ON ambient lighting using the This study explored the effect of ambient lighting on the PERG. The data in this study demonstrate that lights-OFF conditions provide the highest contrast and therefore are likely more reliable for interlaboratory comparisons. Although the study showed that the group lightsON P50 PT to 25` check widths is comparable to lights-OFF P50 PT to standard (50`) checks, the reason for the inter-individual variation of P50 . . .
