ISCEV standard for clinical pattern electroretinography (PERG): 2012 update

Abstract

The pattern electroretinogram (PERG) is a retinal response evoked by a contrast-reversing pattern, usually a black and white checkerboard, which provides information about macular and retinal ganglion cell function. This document from the International Society for Clinical Electrophysiology of Vision (www.iscev.org) is a scheduled revision of the ISCEV PERG Standard, which updates and replaces the 2007 update and all earlier versions. The standard defines a single minimum stimulus and recording protocol for clinical PERG testing to assist practitioners in obtaining good quality responses and to facilitate inter-laboratory comparison. The present revision tightens stimulus specifications, expands on steady-state PERG recording, addresses visual stimulus display distinctions (CRT vs. LCD), and provides a more explicit definition of response components.

Normal Electrooculography in Best Disease and Autosomal Recessive Bestrophinopathy

“…Pattern electroretinograms (PERGs) and full-field ERGs (FFERGs) were used to assess macular function and generalised retinal function respectively. 11,12 All clinical electrophysiological assessments were analysed by one of two consultant electrophysiologists (GH or AR) masked to the molecular diagnosis.…”

Effect of carotid endarterectomy on retinal function in 'asymptomatic' patients with hemodynamically significant carotid artery stenosis

“…[8][9][10] For full-field ERG, the recordings were performed binocularly with the use of bipolar Burian-Allen electrodes (Hansen Ophthalmic Development Lab, Coralville, Iowa, United States) and with an ear clip electrode covered with gold, serving as a ground reference electrode (Natus Europe GmbH, Planegg, Germany) attached to the earlobe. The recording system parameters were as follows: amplifier sensitivity, 10-20-50 µV/div; filters, 0.3-500 Hz (for oscillatory benefit from carotid artery intervention.…”

Association between retinal neuronal degeneration and visual function impairment in type 2 diabetic patients without diabetic retinopathy

“…PERG was performed according to the International Society for Clinical Electrophysiology of Vision standard for clinical patterns [16]. In brief, gold foil corneal recording electrodes were positioned directly under the center of the pupil so that there was no movement of the electrode when the patient blinked.…”
