a Fundus photograph shows a greyish subretinal lesion (arrowhead). Early-phase (b) and late-phase (c) fluorescein angiograms show leakage due to choroidal neovascularization (yellow arrows). d Structural swept source OCT shows a fusiform subretinal hyperreflective lesion, associated with intraretinal fluid and serous retinal detachment. It also shows disruption of the ellipsoid and interdigitation zones associated with triangular-shape hyperreflective material over the RPE. e, f Swept source OCT angiography (OCTA) 3 × 3 mm scan of the outer retina and choriocapillaris shows high-flow neovascular network corresponding to choroidal neovascular membrane (CNVM), area of surrounding hyporeflectivity around the CNVM associated with some areas of flow deficit corresponding to choroidal inflammatory lesions (white arrows). One month after a single intravitreal injection of bevacizumab, structural swept source OCT (g) shows resolution of serous retinal detachment and OCTA (h, i) reveals a decrease in the size of CNVM with a decrease in vessel calibre and branching.
