Brachytherapy using I-125 and a variety of other isotopes in removable episcleral plaques is often used in the treatment of ophthalmic tumors (2, 6, 8, 16, 20, 21, 23). Plaque based brachytherapy permits higher tumor doses with greater sparing of noninvolved tissues compared to x-ray teletherapy. Plaque therapy is more accessible, and less expensive, time consuming, and labor intensive than heavy charged particle teletherapy (4, 9, 10). A Phase III national study, the Collaborative Ocular Melanoma Study (COMS), is currently comparing the efficacy of plaque brachytherapy for moderately large tumors (3 to 8 mm height) versus enucleation.
