There exists a multitude of radiation modalities used to treat ocular, orbital, and adnexal tumors. Each type of radiation machine or method has a characteristic pattern of dose distribution within the eye and orbit. The specific pattern and amount of radiation dose delivered to the eye and orbit can be used to predict radiation-related side-effects. Therefore, some methods are better than others. This podcast provides an overview of radiation sources and explains their differences from an ophthalmic perspective.
