Detection of Silent Type I Choroidal Neovascular Membrane in Chronic Central Serous Chorioretinopathy Using En Face Swept-Source Optical Coherence Tomography Angiography

Figure 3

(a) The colored photo and FFA of the left eye of a 40-year-old male with left chronic CSCR of approximately 1-year duration. The posterior pole shows retinal pigment epitheliopathy in the macular area. FFA of the same eye shows multiple hyperfluorescent leaking points in the macular area that gradually increase in intensity throughout later phases resulting in a diffuse ill-defined hyperfluorescence pattern. (b) The corresponding SS-OCT image in a radial scan mode shows subfoveal shallow neurosensory detachment with subretinal deposits and associated disruption of ELM and IS/OS layers. Note the double-humped irregular PED in the parafoveal area with underlying opaque hyperreflective material (open arrow). The choroid vessels underneath the PED are engorged (star). Subfoveal choroidal thickness is 315 μ. (c) The en face SS-OCTA image of the same eye taken at the level of the outer retina in a 6 mm × 6 mm field. Note the hyperintense signal caused by increased blood flow within the CNV complex composed of tiny intertwining vascular loops (arrow head). (d) The en face SS-OCTA image of the same lesion at the level of the choriocapillaris.
