Multifocal Electroretinography in Diseases with Eccentric Retinal Lesions
Seeliger M. W.
Multifocal electroretinography (mfERG), a method to determine the topographical distribution of retinal dysfunction, has become more widespread in recent years. Recently, guidelines for the basic clinical application of this technique have been established (www.iscev.org). The predominant use of mfERG in diseases centered on the macula like maculopathies and retinitis pigmentosa, together with the default settings implemented by the equipment manufacturers, has caused most users not to look at single elements, but rather to analyze ring-shaped groups. The particular strength of this technique, the topographical resolution, is thereby given away, and affected and not affected areas may even end up in the same group in some cases. This presentation focuses on the diagnostic value of individually formed groups (regions of interest, ROIs) in diseases with eccentric retinal lesions, which allow the analysis of amplitude and implicit time changes without the help of additional software.
