[Irisangiography of rubeosis iridis].

In 66 patients with a rubeosis iridis due to diabetes mellitus (25), old central retinal vein occlusion (22), long-standing secondary angle-closure glaucoma (6), total old retinal detachment (3) and chronic uveitis (10), iris angiography was performed. Typical angiographical findings were found in some of the cases. One can differentiate the different modes of formation of the new vessels; angiographically, rubeosis iridis is never a congestion of preexisting vessels but rather an active vascular proliferation which is always permeable to fluorescein.
