Comparison of Fluorescein Angiography and OCTA. a & b Fluorescein angiography images of a patient with proliferative diabetic retinopathy. These FA images show patchy areas of capillary drop out and presence of neovascularizations elsewhere (NVE). c & d Corresponding OCTA images (generated via ZEISS AngioFlex) of (a) and (b) being superimposed on the FA images. The OCTA images also show areas of capillary drop out and new vessels without leakage
