Diagnostic techniques and tools include the laser Doppler flowmeter (LDF), laser Doppler velocimetry (LDV), retinal vessel analyzer (RVA), retinal function imager (RFI), laser speckle contrast imaging (LSCI), magnetic resonance imaging (MRI), optical coherence tomography angiography (OCTA), pulsatile ocular blood flowmeter (POBF), fundus pulsation amplitude (FPA), colour Doppler imaging (CDI), Doppler optical coherence tomography (DOCT), fluorescein and indocyanine angiography (FA and ICG), retinal oximetry, blue light
entopic phenomenon, and infrared thermography.
Entopic Imagery mentions colours at the corner of the eye, continuing the works is Probability Waves, Essential Whites, In Situ, and 'Gargantua Redacted', a found poem taken from the text of Gargantua and Pantagruel by Francois Rabelais* brings the segment to a close.
