| Outline of Final Research Achievements |
We examined visual evoked potential (VEP), pupil constriction and electroretinogram (ERG) during separate and simultaneous exposure to short pulses of monochromatic light. The pupil constriction during the simultaneous exposure to blue and green-pulsed light was lower than that during the blue-pulsed light despite the double irradiance intensity of the combination. The b/|a| wave of ERG during the simultaneous exposure to blue and green-pulsed light was lower than that during the blue-pulsed light exposure. However, the P100s of VEP during the blue-pulsed light were smaller than those during the simultaneous blue and green-pulsed light and green-pulsed light, indicating that the P100 amplitude might depend on the luminance level. The effects on intrinsically photosensitive retinal ganglion cells by the blue-pulsed light exposure are reduced by the simultaneous irradiation of green light. The blue versus yellow bipolar cells in the retina might be responsible for this phenomenon.
