Contact irradiation of choroidal tumors using Ruthenium106 applicators has become a well-established treatment modality. In order to destroy all tumor tissue while at the same time sparing the neighboring structures of the eye a plaque has to be placed exactly, just overlapping the tumor's base. With transparent plastic replicas with a dark-colored rim and adequate diaphanoscopy this can be accomplished with an otherwise unattainable degree of precision, while at the same time reducing the radiation dose sustained by the surgeon. The design of the replicas and the localization technique are described in detail.
