An EEG survey of 70 normal South African black albinos was carried out to determine whether the lack of pigment in the retinae and eyelids would have any effect on the photoconvulsive response during intermittent photic stimulation. Only 2 out of the 70 (2.85%) showed photosensitivity on intermittent photic stimulation. The results do not confirm the "pigmentary protection theory." Other intrinsic inhibitory factors must be responsible for the level of the photoconvulsive threshold.
对70名南非正常黑人白化病患者进行了脑电图调查，以确定视网膜和眼睑中色素的缺乏是否会对间歇性光刺激期间的光惊厥反应产生任何影响。70名患者中只有2名（2.85%）在间歇性光刺激时表现出光敏性。结果不支持“色素保护理论”。其他内在抑制因素必定是造成光惊厥阈值水平的原因。
