Advantages and drawbacks of some ERG stimulation and data-processing methods.
In each group of diseases, electroretinographic (ERG) diagnosis requires optimal stimulation parameters and detection techniques that clearly evidence any deviations from normal values. Television tube light stimulator assemblies and stimulation techniques applying methods of the control theory are very suitable for the dynamic separation of gross ERG components. The advantages and drawbacks of flicker ERG, frequency-characteristic methods and the frequency ranges that provide useful information in data processing are discussed.
