The low-energy radioactive source iodine-125 is ideal for the irradiation of an intraocular tumor tumor such as a choroidal melanoma. The energy (28 kev) of iodine-125 should be sufficient to allow sterilization of tumors as high as 10 mm. However, shielding of 18-kev photons can be achieved with thin metal (eg, gold) plaques. Thse eye plaques can be individually designed for each eye tumor, depending on its size, shape, and location. This paper deals with the basic considerations and preliminary observations that have lead us to the adoption of iodine-125 as the sole source for the radiation treatment of all intraocular tumors.
低能量放射源碘-125是眼内肿瘤（如脉络膜黑色素瘤）照射的理想选择。碘-125的能量（28千电子伏特）应足以对高达10毫米的肿瘤进行杀菌。然而，18千电子伏特光子的屏蔽可以用薄金属（如金）板来实现。这些眼敷贴可以根据每个眼肿瘤的大小、形状和位置进行单独设计。本文论述了一些基本考量和初步观察结果，这些促使我们采用碘-125作为所有眼内肿瘤放射治疗的唯一放射源。
