title: [Optic disc new vessels (author's transl)].
abstract: Fluorescein angiography gives a classification of optic neovascularization separating early injected from late injected new vessels. This classification has been described in France by Mireille Bonnet. It comes from a hemodynamic and probably from a metabolic reality, and has a great deal to do with prognosis and laser treatment. With regard to the blood supply of the optic nerve head, most of the optic disc new-vessels are probably coming from the vascular plexus which surrounds the lamina cibrosa, and which is itself coming from the uveal circulation. The angiographic of optics-disc new-vessels are very likely explained by a hemodynamic condition which may present a very important variation according to the pathological needs of the retinal metabolism.
