OCT Angiogram Fields of View and Segmentation Layers on Angiovue. The normal left eye of a 56 year old Caucasian man using the Angiovue optical coherence tomography angiography (OCTA) software of the RTVue XR Avanti (Optovue, Inc., Fremont, CA). (A) Full-thickness (internal limiting membrane to Bruch’s membrane) 3 x 3 mm OCT angiogram. (B) Full-thickness 6 x 6 mm OCT Angiogram. (C) Full-thickness 8 x 8 mm OCT Angiogram. (D) Fluorescein angiography cropped to approximately 8 x 8 mm or 30 degrees demonstrates less capillary detail than A-C. (E) 3 x 3 mm OCT angiogram of the “Superficial” inner retina. (F) 3 x 3 mm OCT angiogram of the “Deep” inner retina. (G) 3 x 3 mm OCT angiogram of the outer retina shows absence of vasculature. The white represents noise. (H) 3 x 3 mm OCT angiogram of the choriocapillaris is generally homogenous. There is black shadowing from retinal vessels. (I) En-face intensity OCT image. (J) Highly-sampled OCT b-scan image.
