Table 3 Multimodal imaging features of alterations observed on optical coherence tomography angiography in patients with acute Vogt-Koyanagi-Harada syndrome and acute central serous chorioretinopathy
Feature | Condition | Appearance of choriocapillaris on OCTA | Associated retinal/pigment epithelial/choroidal features | Features on EDI-OCT and/or ICGA |
|---|---|---|---|---|
Dense dark areas | CSC | Single well-defined uniformly hyporeflective areas of apparent flow void | PED | Hyper-reflective dome-shaped elevation of the RPE on EDI-OCT |
Mottled dark areas | CSC | Irregular, areas of mixed hypo- and hyper-reflectance with ill-defined margins | SSRD | Homogenous hyporeflective space between the neurosensory retina and RPE on EDI-OCT |
Multifocal dark spots | VKH | Multiple, round-to-oval, well-defined, variably sized hyporeflective areas suggestive of choriocapillaris flow void | Choroidal inflammatory foci | Choriocapillaris ischemia on ICGA |
