Plaque brachytherapy is a form of targeted radiotherapy used to treat certain ocular tumours, particularly choroidal melanoma. A small radioactive plaque is temporarily placed on the outer surface of the eye, directly over the tumour. The radiation is directed at the tumour while limiting exposure to the surrounding healthy tissues as much as possible.
Who it is for
Plaque brachytherapy is primarily intended for patients with ocular tumours, when radiotherapy is considered an appropriate option to preserve the eye and, where possible, vision. The choice and duration of treatment vary and depend on the size, location, and characteristics of the tumour, as well as the type and activity of the radioactive plaque used.
