Figure 1.
Individual ERG responses for both scotopic and photopic intensity ranges. Left: Dark-adapted series with responses ranging over a 4.9 log unit range. Middle: Light-adapted series with a 2.1 log unit response range. Right: Representative ERG trace depicting measurements. (A) a-Wave amplitude from baseline to the tip of the first negative inflection. (B) b-Wave amplitude from the a-wave to the tip of the first positive peak; ITA: a-wave implicit time from time 0 to (A). ITB: b-wave implicit time from time 0 to (B).
