(a) OCT and (b) OCTA at 40 days from disease onset: (b-1) superficial layer, (b-2) deep layer, (b-3) outer retina layer, and (b-4) choriocapillaris layer of OCTA. (a) OCT shows thinning of the inner retinal layer consistent with the white change on the fundus photograph. (b) OCTA shows a decrease in the flow sign. Compared with at disease onset, the flow sign is improved in all layers, but the improvement is mainly in the superficial layer.
