Multimodal imaging of MEWDS lesions and clinicopathological explanation.

BAF	Hyperfluorescence (increased exposure of RPE lipofuscin following loss of outer photoreceptor segments)
ICGA	Hypofluorescence (intermediate and late phase) (choriocapillaris non-perfusion of endcapillary portions)
SD-OCT	Loss of photoreceptor outer segments
OCTA	No sign of choriocapillaris drop out (OCTA is incapable to image low-flow endcapillary vessels)
FA	Faint hyperfluorescence (possibly due to outer retina ischaemia)

BAF = Blue-light fundus autofluorescence; ICGA = indocyanine green angiography; SD-OCT = spectral domain optical coherence tomography; OCTA = OCT angiography; FA = fluorescein angiography.
