Multifocal electroretinogram (mfERG) is an important diagnostic tool in the clinical evaluation of central electro-retinal function of the macula. To enhance the diagnostic values and to improve its accuracy and internal consistency, it is crucial to examine carefully the endogenous and exogenous factors that affect mfERG recordings and clinical interpretations. This mini review focuses on three aspects of exogenous factors including (1) physiological variations pertaining to age and gender;
