“…These deposits cause retinal and capillary degeneration, such as apoptosis of retinal ganglion cells (RGCs), thinning of the retinal nerve fiber layer (RNFL) and other structural and functional impairments in AD patients [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Optical coherence tomography (OCT) is an optical imaging technique that enables both structural and functional imaging of the retina in humans, as well as a wide range of veterinary animals [ 19 , 20 , 21 ]. OCT angiography (OCTA) allows for the extraction of blood vessels in the retina from OCT data.…”
