408 Ophthalmic Surgery, Lasers & Imaging Retina | Healio.com/OSLIRetina retinal detachments. Subfoveal and posterior pole choroidal thickening was noted (Figures 2A and 2B). FA showed optic disc staining with typical pin- point staining and larger hypofluorescent lesions in the early phase, which leak and become hyper- fluorescent in the late phase, with multi-lobulated pooling of dye in the areas of exudative RDs in both eyes (Figures 3A-3D). Widefield SS-OCTA montage 15 mm × 15 mm, Angio 12 mm × 12 mm, and Angio 6 mm × 6 mm was performed revealing vitreous cells (Figure 4A), exten- sive areas of multifocal exudative RDs in the retina depth-encoded images (Figure 4B), signal attenuation artifacts from the overlying SRF on the choroid layer (Figure 4C), and characteristic areas of flow void at the level of the CC (Figure 4D). The corresponding structural en face image of the choroid and cross- sectional OCT B-scans from choroidal and overlying retinal layers did not show any areas of signal loss, suggesting that the flow void areas in the CC likely represent true loss of flow 7 (Figure 5). Focal hypoper- fusion areas were also observed in deeper choroidal layers. No significant changes in the superficial and deep capillary plexus were identified.
