The electroretinogram (ERG) is a diagnostic test that measures the electrical activity of the retina in response to a light stimulus. The ERG arises from currents generated directly by retinal neurons in combination with contributions from retinal glia.

2025年2月13日 · Basic electroretinogram (ERG) responses as defined by the International Society for Clinical Electrophysiology of Vision, including the additional “recommended” brighter-flash ERG (DA 10.0). The amplitude and peak times are typical, but normal values must be established for each laboratory using local techniques.

The full-field electroretinogram (ERG) is is important for diagnosis and staging of diffuse photoreceptor disease, evaluating the retina-wide function of rods and cones. 5 Delays in cone b-wave implicit times are an early sign of disease and reflect retina-wide involvement.

Electroretinography (ERG) has been included in the 2024 update of the American Academy of Ophthalmology’s (AAO) Preferred Practice Pattern® (PPP) Guidelines for Diabetic Retinopathy (DR). 1 The newly updated PPP, which serves as the gold standard for clinical decision-making, recognizes the value and role of ERG in both diagnosing and managing DR.

2023年7月21日 · Electroretinogram (ERG). Diagram of ERG demonstrating the combined response of rods and cones after bright flash stimulus. The electrical tracing of the ERG (yellow) overlies the retina and the respective cells of origin. The A wave is a negative deflection reflecting the initial hyperpolarization of the photoreceptors as a result of the ...

2025年3月24日 · LKC Technologies, a leader in functional testing using electroretinography (ERG), announces that ERG has been included in the 2024 update of the American Academy of Ophthalmology’s (AAO) Preferred Practice Pattern® Guidelines for Diabetic Retinopathy (DR).

Focal electroretinograms (ERGs) were obtained from the fovea in 142 eyes with a variety of macular diseases and 50 age-matched eyes with acuity loss in which macular disease was ruled out. Across all eyes, the accuracy rate of discriminating macular disease from other causes of acuity loss was 87%.

2025年3月24日 · LKC Technologies, a provider of functional testing through electroretinography (ERG), announced that ERG has been included in the 2024 update of the American Academy of Ophthalmology’s (AAO) Preferred Practice Pattern (PPP) guidelines for diabetic retinopathy (DR).

Abstract: Focal electroretinograms (ERGs) were obtained from the fovea in 142 eyes with a variety of macular diseases and 50 age-matched eyes with acuity loss in which macular disease was ruled out. Across all eyes, the accuracy rate of discriminating macular disease from other causes of acuity loss was 87%.

electroretinography (ERG) responses.1e3 Patients with CDSRR have reduced and delayed cone responses and reduced and markedly delayed rod B-wave at low light intensities, but elevated rod B-wave amplitudes at higher light intensities,1e3 which is the hallmark of the disease.
