[Iris angiograms in malignant melanoma of the uvea].

Iris angiograms were performed in 17 cases of uveal malignant melanoma, which were later histologically confirmed. In those 12 patients in whom the tumour was confined to the choroid, the angiograms revealed a punctate leakage of dye at the pupillary margin, a delayed filling of the vessels in certain areas and definite new vessel formation corresponding to rubeosis iridis. These changes were mostly found in those areas of the iris which corresponded to the choroidal tumour. Five peripheral choroidal melanomas, which involved the ciliary body and encroached into the anterior chamber structures, showed additionally to the dye leakage at the pupillary margin a very light central tumour "borderline fluorescence".
