The electroretinogram. [PDF]

open access: yesArchives of Disease in Childhood, 1989
The electroretinogram, findings, in response to a flash stimulus, was recorded from a skin electrode placed on the bridge of the nose in 4465 infants and children seen over a 10 year period. The electroretinogram was combined with a flash visual evoked potential. From this total, the electroretinographic findings in 240 patients, aged 1 day to 17 years,

Dark-adapted red flash ERGs in healthy adults [PDF]

open access: yes, 2018
Purpose: The x-wave of the dark-adapted (DA) ERG to a red flash reflects DA cone function. This exploratory study of healthy adults aimed to investigate changes in the DA red ERG with flash strength and during dark adaptation to optimise visualisation ...

The multifocal pattern electroretinogram in chloroquine retinopathy [PDF]

open access: yes, 2004
Purpose: Optimal screening for ocular toxicity caused by chloroquine and hydroxychloroquine is still controversial. With the multifocal pattern electroretinogram (mfPERG), a new electrophysiological technique has recently become available to detect early

RdgB2 is required for dim-light input into intrinsically photosensitive retinal ganglion cells. [PDF]

open access: yes, 2015
A subset of retinal ganglion cells is intrinsically photosensitive (ipRGCs) and contributes directly to the pupillary light reflex and circadian photoentrainment under bright-light conditions.

Genetic Dissection of the Drosophila Nervous System by means of Mosaics [PDF]

open access: yes, 1970
Given a mutant having abnormal behavior, the anatomical domain responsible for the deficit may be identified by the use of genetic mosaicism. Individuals may be produced in which a portion of the body is mutant male while the rest is normal female.

A hypothermia mimetic molecule (zr17-2) reduces ganglion cell death, gliosis, and electroretinogram distortion in male rats subjected to perinatal asphyxia

open access: yesFrontiers in Pharmacology, 2023
Introduction: Perinatal asphyxia (PA) represents a major problem in perinatology and may cause visual losses, including blindness. We, and others, have shown that hypothermia prevents retinal symptoms associated to PA.

Age-related deterioration of rod vision in mice [PDF]

open access: yes, 2010
Even in healthy individuals, aging leads to deterioration in visual acuity, contrast sensitivity, visual field, and dark adaptation. Little is known about the neural mechanisms that drive the age-related changes of the retina and, more specifically ...

Relationship between electroretinogram records and clinical signs in patients with various stages of primary open-angle glaucoma

open access: yesJournal of Ophthalmology, 2016
Introduction. Lately, a much attention has been paid to studying the retina in patients with primary open angle glaucoma (POAG). The essence of the process has been reported to be an accelerated death of ganglion cells in the retina and retinal axons ...
