26 | The Electro-oculogram: Clinical Applications | The electrooculogram measures the potential that exists between the cornea and Bruch's membrane at the back of the eye. The potential produces a dipole field with the cornea approximately 5 millivolts positive compared to the back of the eye, in a normally illuminated room. Although the origin of th... | Text | |
27 | The Electroretinogram and Electro-oculogram: Clinical Applications | The global or full-field electroretinogram (ERG) is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease. | Text | |
28 | The Multifocal Electroretinogram: Clinical Applications | The most important development in ERGs is the multifocal ERG (mfERG). Erich Sutter adapted the mathematical sequences called binary m-sequences creating a program that can extract hundreds of focal ERGs from a single electrical signal. This system allows assessment of ERG activity in small areas of ... | Text | |
29 | Visually Evoked Potentials | Detailed explanation of visually evoked potentials. The terms visually evoked potential (VEP), visually evoked response (VER) and visually evoked cortical potential (VECP) are equivalent. They refer to electrical potentials, initiated by brief visual stimuli, which are recorded from the scalp overl... | Text | |
