Imaging of the right eye of Patient 4. Capillary variations are visible from the inner to the outer plexiform layers on the temporal side of the macula. (a) Blue arrow shows sparse micro-aneurysms. (b) Fluorescein angiography (FA) reveals hyperfluorescence from micro-aneurysms on the temporal side of the macula during the early stage of MT type 1. (c) FA showing leakage of fluorescein due to vascular endothelial cell injury during the late stage of MT type 1. (d) No lesion is visible in the inner and outer segment junction (IS/OS) and blue-dotted oval shows sparse micro-aneurysms on en-face OCT. (e) OCT angiography (OCTA) reveals decreased capillary density in the superficial capillary plexus. (f) OCTA image showing the transformational foveal avascular zone (FAZ), aneurysms, and telangiectasia in the deep capillary plexus (DCP) on the temporal side of the macula. (g and h) OCTA images show no changes in the outer or choroidal layers, respectively. (i) SD-OCT shows areas of hyper-reflectance from the inner to the outer plexiform layers on the temporal side. (j) OCTA showing blood flow
