Right-angled vessels (RAVs) are present in early disease stages as shown by optical coherence tomography angiography (OCT-A) before they are visible in funduscopy. Right-angled vessels (RAVs) are present in early disease stages as shown by optical coherence tomography angiography (OCT-A) before they are visible in funduscopy. Fundus photographs and OCT-A (whole retina, superficial, deep and avascular layer) of exemplary eyes of different disease stages. RAVs and their courses are marked by yellow arrowheads. Anastomoses are marked with a yellow-dotted box in the deep and avascular layer, respectively. Note the increasing rarefication of vessels surrounding RAVs with disease progression in the deep and superficial layers. Simone Tzaridis et al.
