Electrophysiology of the retina
WebElectrophysiology. ERG is nearly always abnormal in AZOOR and tends to show a delay in the cone system e.g delayed implicit time of the 30-Hz cone flicker response. Although there is a localized retinal dysfunction, ERG has been observed to be globally affected on full-field testing. WebThe structure of the eye responsible for converting light waves into action potentials is the retina. The neural layer of the retina is composed of three main types of cells: the photoreceptors, the bipolar neurons and the ganglion cells.The photoreceptors, as the name implies, have the responsibility of capturing the light and converting it to an electrical signal.
