利用多焦点ERG对二元核函数的解释经常引起人们的困惑和争议。本文的目的是对核的概念有一个直观的理解，并用模型和例子说明核与个体反应之间的关系。使用双极Burian-Allen隐形眼镜电极的多焦点VERISTMinstrument推导和分析了用于说明该技术各个方面的样本数据。从核心数据合成了响应波形，可以很容易地与传统的闪光、双闪和多闪ERG技术获得的响应波形进行比较。根据单个多焦点记录的核心，合成描述在前一次聚焦闪光后的不同时间的响应的波形。结果表明，观察到的波形自适应变化不仅与闪光间隔有关，还与视网膜偏心率有关。响应波形上的特征表现出独立的自适应行为，表明它们来自不同的视网膜来源。一方面，这里的例子说明了内核中包含的丰富的视网膜动力学信息。另一方面，他们展示了当核序列被转换成具有更直接生理吸引力的表示时，如何促进对多焦点数据的解释。
The interpretation of binary kernels derived by means of the mulifocal ERG has frequently been the source of confusion and controversy. The aim of this paper is to provide an intuitive understanding of the concept of kernels and to demonstrate with models and examples, the relationship between the kernels and individual responses. The sample data used to illustrate the various aspects of the technique were derived and analyzed by means of the multifocal VERISTMinstrument using bipolar Burian-Allen contact lens electrodes. From the kernel data, response waveforms are synthesized that can be readily compared with those obtained with conventional flash, double flash and multi-flash ERG techniques. From the kernels of a single multifocal record, waveforms are synthesized that describe responses at various times after a preceding focal flash. It is shown that the observed adaptive changes in the waveforms depend not only on the flash interval but also on retinal eccentricity. Features on the response waveform exhibit independent adaptive behavior suggesting that they originate from different retinal sources.On one hand, the examples presented here illustrate the rich information on retinal dynamics contained in the kernels. On the other hand, they demonstrate how the interpretation of multifocal data can be facilitated when the kernel series is transformed into representations with more direct physiological appeal.
