Fluorangiography is a very important investigation in order to have a differential diagnosis in all pathological pattern of the conjunctiva of scleral corneal limbus of the sclera of the iris of the ciliary-body. We have in the literature two different patterns: A) Fluorescein negative pattern (cystic neoformations, benign tumors with or without pigment) B) Fluorescein positive pattern (inflammatory pseudotumors, malignant tumors). Authors agree more or less with this classification; they have, moreover, worked out some variations. In our case of a localised carcinoma, fluorescein positive, we did not observe less of fluorescein; in the iris melanoma, even this fluorescein positive, in all observed cases has shown only a small loss of fluorescein near his edges. In the other cases as in the leiomyoma and cystis we agree with the literature even with prudence.
