title: Orbital lymphoma: a simple treatment using electrons.
abstract: Previous papers have discussed the successful treatment of orbital lymphoid tumors using a low-vacuum contact lens placed directly on the eye and the use of a lead bar suspended over the eye with a retort stand. In this paper, a novel approach using a cerrobend bar attached to an electron shield for the treatment of a conjunctival lymphoma is presented. With this approach, the entire eye, excluding the lens, may be treated with a single field. Isodose distributions measured in a water phantom are compared with those planned on a 3D radiotherapy treatment planning system, where the effects of an external eye bar can be shown. The clinical outcome of the treatment is also shown.
