Effect of inner retinal dysfunction on slow double-stimulation multifocal electroretinogram.
PURPOSE This study investigated the retinal adaptive mechanism in inner retinal dysfunction using the slow double-stimulation multifocal electroretinogram (mfERG) paradigm. METHODS Slow double-stimulation mfERG responses were recorded from 15 eyes of 15 4-month-old Mongolian gerbils in control conditions and after suppression of inner retinal responses with injections of tetrodotoxin (TTX) an...
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 کاملEvaluation of inner retinal function in myopia using oscillatory potentials of the multifocal electroretinogram
PURPOSE Oscillatory potentials have been suggested to arise from the inner retina at the level of amacrine cells and inner plexiform layer and they are thought to provide a non-invasive assessment of inner retinal function. We sought to investigate the response dynamics of the inner retina of adult emmetropes and myopes by analysing the oscillatory potentials of the multifocal electroretinogram...
متن کاملThe effect of acute hypoxia and hyperoxia on the slow multifocal electroretinogram in healthy subjects.
PURPOSE To characterize the topographic response of the healthy human retina to acute oxygenation changes in vivo, using multifocal electroretinography (mfERG). METHODS Ten eyes in 10 subjects were examined while they breathed 21% oxygen (normoxia), 10% oxygen (hypoxia, with 90% nitrogen), or 100% oxygen (hyperoxia). Capillary oxygenation was monitored by percutaneous infrared oximetry. RES...
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...
