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

Figure 4

(a) The colored photo and FFA of the left eye of a 35-year-old male with chronic CSCR of approximately 2-year duration. The macular area shows shallow neurosensory detachment. Corresponding FFA shows hyperfluorescent leaking points (arrows). (b) The radial scan SS-OCT image of the same eye demonstrates subfoveal neurosensory detachment with subretinal hyperreflective deposits. A subfoveal flat irregular PED associated with sub-RPE hyperreflective material is seen (open arrow). Subfoveal choroidal thickness is 400 μ. Note the engorged choroidal vessels beneath the PED (star). (c) The en face SS-OCTA image of the same eye at the level of the outer retina in a 4.5 mm × 4.5 mm field. Note the characteristic hyperintense signal of vascular flow within tiny interlacing capillaries in the foveal area (arrow head).
