electroretinography (ERG)

Electroretinography: Out of the laboratory and into the clinicOCT has many benefits, yet falls short of reliably diagnosing and managing retinopathies and glaucoma. ERG remains the stalwart method for this application and this article highlights how technological advancements have enabled its introduction to the clinic.
Adding electroretinography: Technology to clinical utilityPattern electroretinography (PERG) and visually evoked potential (VEP) tests can objectively evaluate the function of axion and retinal ganglion cells. These test results can add another component in successfully treating patients with cataract and/or glaucoma.
How pattern, flicker ERG can impact cataract treatment decisionsRetinal issues can impact cataract surgery outcomes, especially for those with multifocal or other premium lenses. While multifocal lenses may allow the patient to see more clearly across a range of distances, they may also decrease the amount of light that reaches the retina, exacerbating any issues that may already be present.
Improvements in detecting and measuring glaucoma round out 2015As 2015 progressed, researchers reported better ways to detect glaucoma, measure the damage it is causing, and understand how that damage is affecting their patients’ lives. No single innovation revolutionized the profession, but a wide range of technologies became more available to clinicians.
Diopsys portable device aids in detection of retinal pathologiesDiopsys Inc. introduced a tabletop version of its electroretinography (ERG) and visual evoked potential (VEP) testing technology (ARGOS).

Autoimmune retinopathy: While uncommon, viable option for unexplained vision lossOphthalmologists should suspect autoimmune retinopathy if a patient presents with an unexplained visual loss.
Electrophysiology's role in early detection of glaucomaAn office-based system (NOVA Testing System, Diopsys) represents an advance in electrophysiological technology that allows clinicians the ability to detect pathology they have been unable to see in the past, thereby detecting disease early.
