Ocular tumor cells respond well to radiation, but conventional radiotherapy can damage many healthy cells in the eye, leading to vision loss. Brachytherapy (also known as plaque therapy) is a unique, revolutionary treatment method, and Sheba is one of only a few clinics worldwide to administer it.
This therapy uses radioactive iodine 125 plaques that are placed directly on the eye surface, right above the base of the tumor. Using advanced computer software, the size of the plaque is adjusted precisely and customized to be as effective as possible for irradiating the individual’s eye tumor (with consideration for the size and shape of the tumor). This method allows controlled and direct irradiation, without exposing healthy retinal areas to excess radiation. As a result, damage to eyesight is prevented.
