[The measurement of multifocal electroretinography].
OBJECTIVE
Discussing the testing procedure of multifocal electroretinography(ERG).


METHODS
The testing procedure of 131 multifocal ERG records was reviewed.


RESULTS
Some variable factors existed in the measurement of multifocal ERG. These factors included the subject's co-operation, the mounting of electrode, the fixation of tested eye and adjustment of focus. The good records of multifocal ERG depend upon the skill of the operator.


CONCLUSIONS
The testing procedure of multifocal ERG must be standardized so as to ensure the reliability and repeatability of the results.
