Composite after 3 months of therapy in left eye. a Fundus color picture: cotton-wool spots reduced in number and dimensions. New hemorrhages appeared at fundus examination. b Swept source-optical coherence tomography 6 mm scan: no edema or subretinal fluid was visible. Ganglion cell layer thinning is shown in all the areas previously affected by cotton-wool spots (blue arrow). Inner nuclear and outer plexiform layers conserved their wavy aspect (arrowheads). The inner nuclear layer thinned in a few parts (yellow arrow). c Fluorescein angiography: normal diameters of arteries and veins without wall enhancement are shown. Capillary and venule angioectasias inside ischemic areas previously affected by cotton-wool spots are visible (red stars). d Optical coherence tomography angiography: superficial and deep capillary occlusions (red arrows) and capillary angioectasias (red stars) are shown
