Albino rabbits were exposed to strong visible light that had passed several infrared-absorbing filters. Photic damage to the retina and pigment epithelium was studied by means of the direct current electroretinogram (dc-ERG) which allows stable registrations of the slow c-wave from the pigment epithelium as well as the relatively fast a- and b-waves from the neuroretina. The exposure to light for 4 h gave rise to striking changes in the ERG: there was only a 25% decrease in the b-wave but a total disappearance of the normally very large c-wave. At the site of the c-wave in the ERG there appeared a negative trough. The electroretinographic evidence of this study seems to indicate a profound injury to the pigment epithelium (pigment epithelial cells and/or tight junctions) after exposure to strong visible light.
将白化兔暴露于经过多个红外吸收滤光片的强光下。通过直流视网膜电图（dc - ERG）研究视网膜和色素上皮的光损伤，该方法能够稳定记录来自色素上皮的缓慢c波以及来自神经视网膜的相对快速的a波和b波。光照4小时后，ERG出现显著变化：b波仅下降25%，但通常非常大的c波完全消失。在ERG的c波部位出现一个负波谷。本研究的视网膜电图证据似乎表明，暴露于强光后色素上皮（色素上皮细胞和/或紧密连接）受到了严重损伤。
