We recorded the electro-oculogram from 27 normal subjects by means of green and near-ultraviolet (UVA) stimulation. After a 40-minute dark-adaptation period, baseline responses were recorded. In response to the green stimulus, the electro-oculogram increased from this level by an average (+/- standard error of the mean) of 49.5% +/- 4.0%. Although the predicted scotopic effectiveness of the ultraviolet stimulus was more than 3 log units below that of the green stimulus, the near-ultraviolet-induced electro-oculogram increased to an average of 21.9% +/- 3.0% above baseline. This response cannot be due to lens fluorescence to the near-ultraviolet stimulus, since two aphakic subjects had electro-oculographic responses of 32% and 76% above baseline to near-ultraviolet stimuli. Neither the green nor the ultraviolet electro-oculogram changed significantly with age. These large responses to near-ultraviolet stimulation demonstrate the need for standardizing light sources for electro-oculographic testing because the degree of near-ultraviolet irradiance varies considerably according to their design characteristics.
我们通过绿色和近紫外线（UVA）刺激，记录了27名正常受试者的眼电图。在40分钟的暗适应期后，记录基线反应。对绿色刺激的反应中，眼电图从该水平平均增加（±平均标准误差）49.5%±4.0%。尽管紫外线刺激的预测暗视效能比绿色刺激低3个对数单位以上，但近紫外线诱发的眼电图增加到基线以上平均21.9%±3.0%。这种反应不可能是由于晶状体对近紫外线刺激的荧光，因为两名无晶状体受试者对近紫外线刺激的眼电图反应分别比基线高32%和76%。绿色和紫外线眼电图均未随年龄显著变化。对近紫外线刺激的这些大反应表明，由于近紫外线辐照度根据其设计特点有很大差异，因此需要对眼电图测试的光源进行标准化。
