Full-Field versus Multifocal Electroretinography
Full field electroretinography (ffERG) or conventional electroretinography represents the summed electrical response of the entire retina evoked by a flash light from an arc bowl (Ganzfeld stimulus bow) scattered in the eye through a dilated pupil. Clinical applications of ffERG were initiated in the 1940s, therefore clinical and basic studies on ERG date back to several decades. In 1989, the I...
متن کاملRetina in rheumatic diseases: standard full field and multifocal electroretinography in hydroxychloroquine retinal dysfunction.
BACKGROUND The purpose of this study was to evaluate and compare full-field electroretinography (ERG) and multifocal electroretinography (mfERG) results in detecting retinal dysfunction in a large number of asymptomatic patients treated with hydroxychloroquine (Hy). METHODS Fifty eyes in 50 patients with rheumatic diseases who had been using Hy for a period of time ranging from 30 months to 1...
متن کاملChlorogenic Acid Supplementation Improves Multifocal Electroretinography in Patients with Retinitis Pigmentosa
To evaluate the effect of chlorogenic acid supplementation in patients with retinitis pigmentosa, we evaluated objective change in visual function with multifocal electroretinography, along with visual acuity, visual field, standard electroretinography, and contrast sensitivity. Eighteen patients diagnosed with retinitis pigmentosa were enrolled in this prospective, non-comparative, single-arm ...
متن کاملFrequency Domain Electroretinography in Retinitis Pigmentosa versus Normal Eyes
PURPOSE To compare electroretinogram (ERG) characteristics in patients with retinitis pigmentosa (RP) and normal subjects using frequency domain analysis. METHODS Five basic ERG recordings were performed in normal subjects and patients with a clinical diagnosis of RP according to the ISCEV (International Society of Clinical Electrophysiology of Vision) protocol. Frequency domain analysis was ...
متن کاملNoninvasive assessment of retinal function in rats using multifocal electroretinography.
PURPOSE To assess the applicability of multifocal electroretinograms (mfERGs) for evaluation of function in this small-eyed animal with a rod-dominant retina that is often used to model retinal diseases. METHODS Noninvasive monocular mfERGs were recorded in anesthetized albino (Sprague-Dawley) and pigmented (Long Evans) rats. Achromatic stimuli subtending a 49 degrees by 53 degrees field cons...
