Overview
The multifocal electroretinogram (mfERG) is a significant advancement in diagnosing and characterizing retinopathy. It allows for the mapping and quantification of scotomas and retinal dysfunction through a mathematical average of b-wave approximations.

What is a multifocal electroretinogram?
It is a diagnostic tool that measures electrical responses from multiple areas of the retina.
How does mfERG differ from traditional electroretinograms?
mfERG analyzes multiple retinal areas simultaneously, providing a more detailed assessment.
What conditions can mfERG help diagnose?
It is primarily used to diagnose various forms of retinopathy and retinal dysfunction.
How quickly can mfERG results be obtained?
Results can be derived in just a few minutes per eye.
Is mfERG widely used in clinical practice?
Yes, it is becoming increasingly common in ophthalmology for diagnosing retinal issues.
