Record 1 2026-03-23

English

Subject field(s)
  • Electrodiagnosis
  • The Eye
CONT

In contrast to ffERG [full-field electroretinography],... focal macular ERG(fmERG) allows examination of retinal function within only the macular area.

OBS

electroretinography: ... the measurement of electrical potentials generated by the retina in response to light.

Key term(s)
  • focal macular electro-retinography

French

Domaine(s)
  • Électrodiagnostiques

Record 2 2026-02-19

English

Subject field(s)
  • Electrodiagnosis
  • The Eye
CONT

A full-field ERG is generated by stimulating the entire retina with a flash light source under varying conditions of retinal adaptation to dark and light.

OBS

electroretinogram: A record of the electrical activity of the retina in response to stimulation by light.

Key term(s)
  • full-field electro-retinogram

Record 3 2026-02-19

English

Subject field(s)
  • Electrodiagnosis
  • The Eye
CONT

Pattern ERG(pERG)... was designed to complement the full-field ERG [electroretinography] in differentiating between maculopathy and generalized retinopathy. pERG uses an alternating pattern-reversal stimuli(i. e., checkerboard pattern) to assess the central retina region. It has been used as a sensitive indicator of dysfunction to detect subtle optic neuropathies.

Key term(s)

English

Subject field(s)
  • Electrodiagnosis
  • The Eye
CONT

Full-field electroretinography(ERG) is a visual electrophysiology test that measures the pan-retinal response by capturing the sum of responses from the entire retina when exposed to flashes of light. This test is essential for diagnosing and monitoring various retinal dysfunctions, including retinopathies, vascular conditions, and unexplained vision loss.

OBS

electroretinography: ... the measurement of electrical potentials generated by the retina in response to light.

Key term(s)

Record 5 2025-08-27

English

Subject field(s)
  • Visual Disorders
CONT

Occult macular dystrophy(OMD), also known as Miyake's disease, is an aptly named inherited macular disorder characterized by poor central acuity despite a normal-appearing fundus, FA [fluorescein angiography], and full-field ERG [electroretinogram].... OMD typically exhibits an autosomal dominant form of inheritance due to mutations in the retinitis pigmentosa 1-like 1(RP1L1) gene located on the short arm of chromosome 8.

Key term(s)
  • Miyake disease

French

Domaine(s)
  • Troubles de la vision
CONT

Dystrophie maculaire occulte («occult macular dystrophy»). [...] affection rare, caractérisée par une baisse progressive de l'acuité visuelle malgré un fond d'œil normal. [...] Mutations dans le gène «retinitis pigmentosa 1-like protein 1 gene (RP1L1)» sur le chromosome 8p23.1. [...] Transmission [autosomique] dominante.
