The newest imaging technology is only at RCH and could possibly replace the gold standard of FA and ICG. OCTA follows a similar method of imaging techniques of the general OCT, but it essentially provides visualization of microvascular blood flow. Not only is it capable of showing vascular abnormalities, but it can create intensity-based OCT cross sections and en face visualization that can identify structural changes such as increased retinal thickness. Blood flow can also be detected in three dimensions on OCTA, which gives information on different depths, as opposed to one depth on FA and ICG.
