Recent research has focused on the photopic negative response (PhNR), a component of the electroretinogram (ERG) that reflects the function of retinal ganglion cells (RGCs). The PhNR is ...

The specialist performed an electroretinogram (ERG), a procedure in which a tiny electronic sensor placed on the eye measures the retina’s response to bursts of light. A healthy retina will ...

The most commonly used methods for detecting retinal dysfunction in humans are psychophysical (e.g., perimetry) or electrophysiological (e.g., electroretinogram [ERG]). Several of those techniques ...

have dramatically reduced retinal function according to electroretinogram (ERG) recordings (Côté et al, 2005; Smith and Côté, 2012). Interestingly, the visual defect originates at the level of the ...
