Electroretinography (A Review)

open access: yesFolia Veterinaria, 2016
Electroretinography (ERG) is a functional test of the outer retina. During an examination, the retina is selectively stimulated. The stimulation of the retina produces a response of the individual retinal cells and reveals information about its function.

Enhancing Electroretinogram Classification with Multi-Wavelet Analysis and Visual Transformer

open access: yesSensors, 2023
The electroretinogram (ERG) is a clinical test that records the retina’s electrical response to light. Analysis of the ERG signal offers a promising way to study different retinal diseases and disorders.
