The ERG-Thread is a corneal electrode used to record the electroretinogram (ERG), produced by light stimulation of the retina, suitable for human or animal application.*
The sensor consists of a thin silver-Nylon thread, which is placed on the cornea to capture the signals from the retina.
ERG-Thread is an electrode intended to be placed on the corneal or conjunctival fornix or scleral area to transmit electrical signals for subsequent measurement and recording of electroretinography (ERG), to support the diagnosis of retinal dysfunctions. It can be used to perform either fullfield ERG or multifocal ERG or Pattern ERG assessment.
