Seven weeks later, the degree of vascular sheathing, beading, and tortuosity has decreased, while intraretinal hemorrhage and exudate have increased in both eyes (a and b). Early-phase fluorescein angiography, right eye (c) and left eye (e), shows a blocking defect by retinal hemorrhage, vascular occlusion, and aneurysmal changes. Early frames of the nasal retina of the right eye (d) and left eye (f) show vascular leakage and global areas of non-perfusion
