Popis: Background: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. Aim: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC). Two patients with central retinal artery occlusion (CRAO), 1 with arteritic anterior ischemic optic neuropathy (AAION), and 3 healthy subjects were studied. Results: The Angio-OCT imaging afforded better visualization of the depth of the RPC and rest of the vascular layers of the retina compared with FAG. Optic nerve surface perfusion was affected in AAION and proved normal in CRAO. Conclusions: Our results indicate that perfusion of the papilla and RPC mainly arises from the papillary plexus that depends on the posterior ciliary artery.
