[Systematisation of the choroïdal vasculature (author's transl)]

The systematization of the choroïdal vasculature has been studied by injection of radio-opaque material. The most important points are:--the absence of specific macular arteries,--the presence of two different clusters of short posterior ciliary arteries: a para-optic cluster and a remote cluster,--the inconstant presence of anterior recurrent ciliary arteries,--the absence of anastomoses between the S.P.C.A. arteries,--the segmental distribution of the capillaries,--the lobules are autonomous, but non independent,--the greatest variability of that systematization.
