title: [Circular neovascularization of the circulus arteriosus iridis minor].
abstract: Vessel duplications of the anastomosis of the cirulus arteriosus iridis minor were observed in 15 patients with diabetes mellitus and in four patients with retinal venous occlusion, in a total of 1192 iris angiograms made. In each of these cases there is a bilateral neo-vascularization that may be regarded as an indication of a general vascular disease. It could be a fairly unaggressive process of new vessel formation in the iris which, during four years of observation, has in none of the cases observed developed into a rubeosis iridis visible under the slit lamp.
