Authors present their observation of 28 pigmented tumors of the iris and iridoci- liary region during 8 years. While deciding whether to continue in observation or to indicate surgery, they were concentrated on observation of blood supply’s abnormalities of pigmented mass and defect of blood-aqueous barrier during the iris angiography. Melanoma - mostly celullar type of high malignity - was confirmed in 11 cases, pigmented meduloepithelioma in 1 case, pigmented naevus in 2 cases out of 14 patients indicated for surgery. Authors correlated angiographical pictures with clinical observation and histo- pathological findings.
