Lutein, RR-zeaxanthin (3R,3’R-zeaxanthin) and RS (meso)-zeaxanthin (3R,3’S-RS- zeaxanthin) (L/Zi) treatment rescued retinal function in light-damaged retinas. Typical waveforms of electroretinogram (ERG) and luminance-response curves of BALB/cJ mice before (9–11 weeks old) and after (11–13 weeks old) blue light exposure in vehicle (sunflower oil) and L/Zi treatment groups (n = 7 in each group). (a) Typical dark-adapted ERGs waveforms; (b) Typical light-adapted ERGs waveforms; (c) Luminance-response curves of a-wave amplitudes in dark-adapted conditions which are associated with the responses from rod and cone photoreceptors; (d) Luminance-response curves of b-wave amplitudes in dark-adapted condition which are associated with the responses from bipolar cells in both rod and cone pathways; (e) Luminance-response curves of b-wave amplitudes in light-adapted condition which are associated with the responses from bipolar cells in the cone pathway. Error bars indicate standard errors. Pre-LE: Before light exposure. Post-LE: After light exposure.
