Human Electroretinal Responses to Grating Patterns and Defocus Changes by Global Flash Multifocal Electroretinogram
The electrical response of the retina was examined as a function of retinal region, using stimuli of various spatial frequencies in the first experiment. In the second experiment, the regional response of the retina to defocus at high and low spatial frequencies was investigated. Twenty three subjects were recruited for global flash multifocal electroretinogram (mfERG) in experiment 1. Black an...
متن کاملPorcine global flash multifocal electroretinogram: Possible mechanisms for the glaucomatous changes in contrast response function
PURPOSE The aim of this study was to obtain a better understanding of the cellular contributions to the porcine global flash mfERG by using a pharmacologic dissection method, together with the method using variation of stimulus contrast which has been used to demonstrate mfERG changes in human glaucoma. METHODS Global flash mfERGs with different stimulus-contrast settings (99%, 65%, 49% or 29...
متن کاملSlow flash multifocal electroretinogram in myopia
PURPOSE The purpose of this study was to investigate the characteristics of retinal function in myopes using a modified multifocal electroretinogram (mfERG) protocol, the slow flash (sf-mfERG) paradigm, which is thought to primarily reflect responses of ON- and OFF-bipolar cells and emphasize the late response components. METHODS Twenty-eight subjects (10 emmetropes and 18 myopes) underwent m...
متن کاملMultifocal electroretinogram delays reveal local retinal dysfunction in early diabetic retinopathy.
PURPOSE To identify local retinal abnormalities in diabetic patients with and without retinopathy, by using the multifocal electroretinogram (M-ERG). METHODS Electroretinograms were recorded at 103 discrete retinal locations in each eye of eight persons with nonproliferative diabetic retinopathy (NPDR) and eight diabetic persons without retinopathy, using VERIS (EDI, San Mateo, CA). The ampli...
متن کاملRetinal function in normal and diabetic eyes mapped with the slow flash multifocal electroretinogram.
PURPOSE It has been suggested that late components of the standard multifocal electroretinogram (mfERG) are preferentially affected by diabetes mellitus. The slow-flash (sf-)mfERG stimulates with flashes separated by dark periods, facilitating interpretation of late first-order response components compared with standard multifocal stimulation. Retinal function and response component changes wer...
