Optical Coherence Tomography Angiography in Central Serous Chorioretinopathy

Figure 5

Central serous chorioretinopathy in a 52-year-old man with abnormal choroidal vessels on OCTA, but no evidence of CNV on multimodal imaging. Late phase of fluorescein angiography (FA (a)), early and late phase of indocyanine green angiography (ICGA (b) and (c)), OCTA (d, e, f), and coregistered OCT B-scan (d′, e′, f′). Late phase of ICG revealed faint hyperfluorescent points, which are usual features of CSR [13] but no clear evidence of neovascular choroidal membrane. Automatically segmented outer retina OCTA image did not show any evidence of hyperdense abnormal signal (d). Manually segmented outer retina OCTA image showing a moderate abnormal hyperdense signal (e). Automatically segmented choriocapillaris OCTA image showing an abnormal choroidal vessel (arrow) with a tangled pattern lesion. OCT revealed mild flat irregular PED and SRD (d′, e′, f′, g). This patient was not treated. After one-month follow-up, the SRD spontaneously decreased (38 microns), arguing in favor of absence of neovascular lesion (h, i).
