Phoenix Image-Guided Focal ERG

Phoenix Research Labs’ Image-Guided Focal ERG System quantitatively determines retinal function at precisely located positions and outputs a spatial map of retinal performance to facilitate assessment of treated versus non-treated regions. This is enabled using a deep red image and a deep red probe spot, seen on the Micron image in real time, and then flashing a white light stimulus and recording the electrical signal.

The Image-Guided ERG modality functions as an attachment to the Micron Retinal Imaging System, maximizing laboratory space. The Micron IV provides illumination and imaging at 850 nm, supporting the highest levels of dark adaption
