Clinical course of two siblings with potassium voltage-gated channel modifier subfamily V member 2 (KCNV2)-associated retinopathy
ConclusionsThe siblings had clinical findings typical of CDSRR. High-intense flash ERG is recommended for identifying pathognomonic “squaring” a-waves in patients with CDSRR. (Source: Documenta Ophthalmologica)

Slope between positive and negative ERG components in patients with open-angle glaucoma
ConclusionsThe P50-N95 slope is a sensitive indicator of RGC dysfunction in patients with open-angle glaucoma. A similar component of LA-ERG, the b-PhNR slope, is less affected by glaucomatous RGC dysfunction and probably originates from similar retinal mechanisms as the b-wave.

Morphological and Functional Correlations in Acute Central Serous Chorioretinopathy
ConclusionsSRF and CRT could serve as the most representative morphological proxies for visual function deficit in acute CSC patients. Retinal sensitivity, as measured by MP, may be superior to BCVA in clinical research studies or when an in-depth visual function evaluation is needed. (Source: Documenta Ophthalmologica)

ISCEV standard for clinical pattern electroretinography (2024 update)
AbstractThe pattern electroretinogram (PERG) is a localized 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 (ISCEV;www.iscev.org) presents an updated and revised Standard for clinical PERG testing. This replaces the 2013 and all earlier versions. Minimum protocols for basic PERG stimuli, recording methods and reporting are specified, to promote consistency of methods for diagnosis and monitoring purposes, while re...

Electroretinographic oscillatory potentials in Leber hereditary optic neuropathy
ConclusionsReduced OPs in LHON patients may represent disturbed neuronal interactions in the inner retina with preserved photoreceptoral (a-wave) to bipolar cell (b-wave) activation. Reduced DA OP2 and high-cutoff LA OP alterations may be further explored as functional measures to characterize LHON status and progression. (Source: Documenta Ophthalmologica)

Effect of eccentric fixation on the steady-state pattern electroretinogram
ConclusionGenerally, moderate inaccuracies of fixation do not have a sizable effect on ssPERG amplitude. However, with large checks, the luminance response has to be considered. (Source: Documenta Ophthalmologica)

Sensitivity and specificity of the uniform field electroretinogram in glaucoma detection in comparison to the pattern electroretinogram
ConclusionsPERG bar stimuli and the PhNR of the UF-ERG can be used in the clinical setting to detect glaucoma-related changes in glaucoma-suspect and glaucoma patients. However, our data confirm that the PhNR peak time has the best combined sensitivity and specificity. (Source: Documenta Ophthalmologica)

ISCEV and IPS guideline for the full-field stimulus test (FST)
AbstractThe full-field stimulus test (FST) is a psychophysical technique designed for the measurement of visual function in low vision. The method involves the use of a ganzfeld stimulator, as used in routine full-field electroretinography, to deliver full-field flashes of light. This guideline was developed jointly by the International Society for Clinical Electrophysiology of Vision (ISCEV) and Imaging and Perimetry Society (IPS) in order to provide technical information, promote consistency of testing and reporting, and encourage convergence of methods for FST. It is intended to aid practitioners and guide the formulati...
