由于光刺激和记录技术的差异，[人类]视网膜电图（ERG）的评估方法使得实验室之间的数据交换变得困难。除现有技术外，B波与a波的关系可能是评价ERG的有用指标。在暗适应状态下记录由相对明亮的闪光引起的ERG反应。作为a波振幅的函数的B波振幅的曲线图描述了视网膜的功能完整性。一个功能正常的视网膜应该引起符合正常曲线的ERG反应，而不管用于ERG记录的仪器。唯一的限制是使用全场照明。该方法基于关于ERG组分来源的生理学考虑。这种方法将促进中心之间的数据交换，也可用于视网膜的临床评估。
The methods for the assessment of the electroretinogram (ERG) [from humans] make the exchange of data between laboratories difficult owing to differences in photostimulation and recording techniques. In addition to present techniques the b wave to a wave relationship may be a useful index for evaluating the ERG. The ERG responses evoked by relatively bright flashes are recorded in the dark-adapted state. A plot of the b wave amplitude as a function of the a wave amplitude describes the functional integrity of the retina. A normally functioning retina should elicit an ERG response that fits the normal curve regardless of the apparatus used for ERG recording. The only constraint was the use of full-field illumination. This method was based on physiological considerations regarding the origin of the ERG components. Such a method will facilitate data exchange between centers and can also be used for clinical assessment of the retina.
