[The characteristics of the nucleolar organizer in tumors of the choroid of the eye].
26 intraocular melanomas were studied histologically, ultrastructurally and morphometrically. For the first time the impregnation method was used for visualization of the nucleolar organizer (NO) in the cells of eye tumors using silver salts on the deparaffined sections. The efficiency and reliability of this method in the determination of the degree of malignancy of intraocular melanomas are demonstrated. A correlation existed between long-term postoperative results and the nucleolar organizer index (NO number/number of nuclei). The method can be practiced in any pathohistologic laboratory.
