epiretinal membrane with Cirrus imaging

This is a good example of an epiretinal membrane causing a patient some issues.  The ERM, or epiretinal membrane, is a sticky substance, made up of leukocytes, protein, inflammatory debris, that is "hyper-reflective."  It is in the top most part of the video that appears to be a bridge over the various valleys of the scan.  We use the term "hyper reflective" in regard to certain elements of OCT scans, since we are only using a non-invasive, near infrared light source.  This is in contrast to fluorescein angiography, which requires an injectable dye, intra-venous.  In regard to angiography, we use the term "hyper fluorescence," since the dye itself is what is illuminated in an angiography.  See if you can spot the ERM in the video.
