Ocular melanoma is frequently treated using brachytherapy implants (such as125 I and60 Co plaques or184 Ta wire), surgery, or external beam radiotherapy using small60 Co beams, high energy x‐rays, or proton therapy. The last technique, though very expensive, provides improved dose distributions and dose localizations in the treatment of tumours adjacent to critical normal tissues. The technique of fractionated stereotactic radiotherapy is now being used at an increasingly large number of centers in the treatment of lesions in the brain, and the head and neck. This article describes the successful extension of the stereotactic technique to the treatment of ocular melanoma: an eye fixation aid is attached to a noninvasive, relocatable Gill‐Thomas‐Cosman head frame together with a simple eye‐movement tracking system.
