Many kinds of radiation have been used to treat choroidal melanoma. However, they can be divided into two main categories, implanted radiation plaques and externally administered radiation beams. While the most common radiation plaques include: ruthenium-106, iodine-125 and palladium-103, external beam is dominated by proton therapy. The literature suggests that both plaques and proton beam can be used to destroy intraocular tumors. However, they are very different in their radiation dose distribution within the eye and orbit. These differences result in a different pattern, incidence and distribution of radiation side-effects. This episode examines how each form of radiation is applied, the ability of each form of radiation to compensate for eye movements as well as what results the patient and doctor should expect over time. This podcast episode presents Dr. Finger’s decades of experience with ophthalmic radiation therapy, his knowledge gained working with the American Academy of Physicists in Medicine and as Chair of the 2014 AJCC-OOTF Ophthalmic Plaque Radiation Therapy Guideline Initiative for the American Brachytherapy Society.
