If the tumor is small enough, other therapies such as external beam radiation therapy, photocoagulation, cryotherapy, thermotherapy, chemotherapy, and brachytherapy may be considered.
In internal radiation (brachytherapy), radioactive liquid or pellets are delivered to the cancerous site via a pill, injection, or insertion in a sealed container.
Smaller, more localized tumors can sometimes be treated by local therapies such as cryotherapy, photocoagulation therapy, thermotherapy or brachytherapy.
Brachytherapy involves the application of radioactive material to the outer surface of the eye at the base of the tumor.
Chemotherapy is sometimes used to shrink tumors prior to other treatments such as radiation therapy or brachytherapy.
