Electrooculography (EOG) is a technique for measuring the resting potential of the retina. The EOG is used to assess the function of the pigment epithelium. During dark adaptation, the resting potential decreases slightly and reaches a minimum ("dark trough" or "Dt") after several minutes. When the light is switched on, a substantial increase of the resting potential occurs ("light peak" or "Lp"), which drops off after a few minutes when the retina adapts to the light. The ratio of the voltages (i.e., light peak divided by dark trough) is known as the Arden ratio and is normally above 1.80. The Arden ratio is often abnormal in retinitis pigmentosa, diabetic retinopathy, detached retina, Best disease and many other eye disorders.

LP420843-7 Electroretinogram.multifocal
A multifocal electroretinogram (mfERG) is a type of ERG. An ERG measures retinal electrical activity using a corneal electrode; an mfERG measures that activity in smaller areas of the retina in order to find local variation and pinpoint areas of dysfunction. PMID: 22038576

LP420845-2 N1 amplitude
The waveform found on a multifocal electroretinogram (mfERG) is typically a biphasic wave. The first deflection is negative, the second is positive, and the third is negative, and the three peaks are called N1, P1, and N2, respectively. The amplitude and implicit time can be measured for each, though P1 amplitude and implicit time are the most common measurements. PMID: 22038576

When the light is switched on, a substantial increase of the resting potential occurs ("light peak" or "Lp"), which drops off after a few minutes when the retina adapts to the light. The ratio of the voltages (i.e., light peak divided by dark trough) is known as the Arden ratio and is normally above 1.80. The Arden ratio is often abnormal in retinitis pigmentosa, diabetic retinopathy, detached retina, Best disease and many other eye disorders.

LP420843-7 Electroretinogram.multifocal
A multifocal electroretinogram (mfERG) is a type of ERG. An ERG measures retinal electrical activity using a corneal electrode; an mfERG measures that activity in smaller areas of the retina in order to find local variation and pinpoint areas of dysfunction. PMID: 22038576

LP420846-0 N2 amplitude
The waveform found on a multifocal electroretinogram (mfERG) is typically a biphasic wave. The first deflection is negative, the second is positive, and the third is negative, and the three peaks are called N1, P1, and N2, respectively. The amplitude and implicit time can be measured for each, though P1 amplitude and implicit time are the most common measurements. PMID: 22038576

LP200598-3 light-adapted
Electrooculography (EOG) is a technique for measuring the resting potential of the retina. The EOG is used to assess the function of the pigment epithelium. During dark adaptation, the resting potential decreases slightly and reaches a minimum ("dark trough" or "Dt") after several minutes. When the light is switched on, a substantial increase of the resting potential occurs ("light peak" or "Lp"), which drops off after a few minutes when the retina adapts to the light. The ratio of the voltages (i.e., light peak divided by dark trough) is known as the Arden ratio and is normally above 1.80. The Arden ratio is often abnormal in retinitis pigmentosa, diabetic retinopathy, detached retina, Best disease and many other eye disorders.
