Human scotopic dark adaptation: Comparison of recoveries of psychophysical threshold and ERG b-wave sensitivity

Ruseckaite, Rasa; Lamb, Trevor; Pianta, M.J; Cameron, Allison


We have compared the time course of dark adaptation of the human scotopic visual system, measured psychophysically and from the b-wave of the electroretinogram (ERG), for bleaches ranging from a few percent to near total. We also measured light adaptation, in order to apply a "Crawford transformation" to convert the raw measurements of dark adaptation into equivalent background intensities. For both the "psychophysical threshold equivalent" intensity and the "ERG b-wave sensitivity equivalent"...[Show more]
