AIMS To describe the topography of multifocal electroretinograms (ERGs) and to explore its diagnostic value in patients with Stargardt's macular dystrophy (SMD). METHODS 51 patients with SMD were examined by means of the m-sequence technique to characterise the topography of electroretinographic responses in the central visual field. The results were compared with data from 30 normal voluntee...
Introduction: Multifocal electroretinography (ERG) is an examination which measures retinal electrical activity as a response to lighting stimulus and allows simultaneous recording in many topographic locations. Various electrodes have been developed balance accuracy also patients’ comfort. The objective of this study establish normal values multifocal ERG compare the comfort level using Jet, D...
We evaluated the color vision of mercury-contaminated patients and investigated possible retinal origins of losses using electroretinography. Participants were retired workers from a fluorescent lamp industry diagnosed with mercury contamination (n = 43) and age-matched controls (n = 21). Color discrimination was assessed with the Cambridge Colour Test (CCT). Retinal function was evaluated by u...
