Figure 1: Effect of background illumination on the ERG in control (non-diabetic) rats housed under standard lighting conditions.
From: Light adaptation does not prevent early retinal abnormalities in diabetic rats
(a) ERG responses to flash stimuli of 1.50 log cd.s/m2 recorded under dark-adapted (0 lux background) and dim- and light-adapted conditions (background light intensities of 0.3, 3 and 30 lux). (b,c) Intensity-response relations for the a-wave (b) and the b-wave (c) under different background illuminance conditions. N = 5 rats. Background light levels as low as 0.3 lux light adapt the retina. ***P < 0.001 for multiple comparisons between ‘0 lux’ and background light intensities of 0.3, 3 and 30 lux. Error bars here and in other figures denote ± s.e.m.
