Proton radiotherapy as an alternative to exenteration in the management of extended conjunctival melanoma.

Background: Diffuse and multifocal patterns of conjunctival melanoma may not be treatable with standard eye-sparing methods. The purpose of this study was to evaluate the usefulness of proton beam radiation therapy as an alternative to exenteration.

Methods: Twenty patients with extended conjunctival melanoma were treated by proton beam irradiation.
