ISCEV standard for clinical pattern electroretinography (2024 update)

Documenta Ophthalmologica
The 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.

Full‐field Electroretinography in Age‐related Macular Degeneration: can retinal electrophysiology predict the subjective visual outcome of cataract surgery?

Acta ophthalmologica, 2020
Predicting the visual gain from cataract surgery when the main cause of vision loss is age‐related macular degeneration may be difficult and warrants the need for an objective predictor of subjective outcome.

Structure and function of retinal ganglion cells in subjects with a history of repeated traumatic brain injury

Frontiers in Neurology, 2022
This study tested whether repeated traumatic brain injuries (TBIs) alter the objective structure or the objective function of retinal ganglion cells (RGCs) in human subjects recruited from an optometry clinic.

Macular Impairment in Fabry Disease: A Morpho-functional Assessment by Swept-Source OCT Angiography and Focal Electroretinography.

Investigative Ophthalmology and Visual Science, 2019
Purpose Fabry disease (FD) is a multiorgan X-linked condition characterized by a deficiency of the lysosomal enzyme alpha-galactosidase A, resulting in a progressive intralysosomal deposit of globotriaosylceramide.
