Abstract
Venous loops are relatively rare manifestations of diabetic retinopathy. The authors describe a case characterized by the development of a venous loop during a 3-year period. Optical coherence tomography angiography (OCTA) revealed a hyperintense signal from the lesion, attesting an ordinary flow into the venous loop. OCTA also showed an area of capillary loss in proximity of the lesion, which is in agreement with the proposed pathogenesis for venous loops, developed to bypass an area of retinal vessels occlusion.
