Multifocal Imager 3GEN ™

Multifocal Imager 3GEN ™ The Multifocal Imager System is a product used for multifocal Multifocal Electroretinography (mfERG) It has been developed at Gartnavel General Hospital, Glasgow, UK by David Keating and Stuart Parks. It is the product of over 14 years research experience gained in the investigation of more than 6,000 patients.

The product produces map of the function of the retina by using software and hardware that provides combined spatial and temporal information on visual function. The default mfERG and mfVEP full M-sequence test takes 8 minutes to perform with sixteen 30 second segments. The unit provides advanced analysis techniques for the operator including wavelet filtering, smart digital filtering, signal to noise ratio analysis and advanced artificial intelligence features.

Multifocal Imager 3GEN ™ The multifocal is a class IIA CE marked medical device.
