The electroretinogram (ERG) and electro-oculogram (EOG) are two of the most frequently used visual electrodiagnostic tests of retinal function. The ERG and EOG are easily measured, but there are many engineering difficulties in processing their signal data because the response amplitudes are relatively small, and the relevant signals are buried in electromagnetic and biologic noise. These tests tend to be time consuming, so they lend themselves to automatic control. This article describes the engineering designs relative to a microprocessor-based electrophysiologic laboratory at Emory University Clinic to perform ERG, EOG, and other clinical tests of retinal function. A comparable system that offered both the ability to accept data from a variety of transducers and the flexibility to permit all of the planned testing protocols was not available from any commercial source.
视网膜电图（ERG）和眼电图（EOG）是视网膜功能最常用的两种视觉电诊断测试。ERG和EOG易于测量，但处理其信号数据存在许多工程难题，因为响应幅度相对较小，且相关信号被埋在电磁和生物噪声中。这些测试往往耗时较长，因此适合自动控制。本文介绍了与埃默里大学诊所基于微处理器的电生理实验室相关的工程设计，以进行ERG、EOG及其他视网膜功能的临床测试。任何商业来源都没有提供一个既能接受来自各种换能器的数据，又能灵活允许所有计划测试方案的类似系统。
