Morphologic patterns of macular neovascularization (MNV) as visualized using swept-source OCT Angiography. Shape descriptors included (A) the “Medusa” pattern representing a lesion where vessels radiate in all directions; (B) the “Sea-fan” pattern representing a lesion where blood vessels radiate in all directions from one side; and (C) the “Tree-in-bud” pattern representing a round lesion with no obvious vascular trunk. Images were also evaluated for the presence of (D) peripheral loops (indicated by the yellow arrows), (E) capillary fringe (indicated by the yellow arrows), a perilesional dark halo (indicated by the box) and (F) a core vessel (indicated by the yellow arrows).
