Present treatments for intraocular retinoblastoma cure 99% of children but have significant toxicity. Enucleation of the eye is effective but blinds the eye and leaves a lifelong cosmetic deformity. Radiation is associated with the subsequent development of fatal cancers. Systemic (intravenous)chemotherapy is used worldwide but experience with it has shown that the majority of eyes initially treated with chemotherapy still require additional treatments, such as radiation, laser, cryotherapy or even enucleation. In addition blood transfusions, secondary infections, insertion of ports and permanent hearing loss are now well reported. Three years ago we developed this technique of Chemosurgery for significantly increasing the dose of drug to the cancer while decreasing the dose of drug administered to children. This approach has decreased the need for enucleation in advanced eyes scheduled for enucleation with minimal systemic toxicity. We now offer treatment of both eyes simultaneously (in bilateral cases) and to eyes with less advanced disease and normal vision as an alternative to toxic systemic chemotherapy. In cases of very advanced ocular disease we will be using multiple drugs infused at the same session to increase tumor kill.
