Abstract

Proton beam radiotherapy of uveal melanoma and other malignant and benign ocular tumors has shown tremendous development and success over the past four decades. Proton beam is associated with the lowest overall risk of local tumor recurrence in uveal melanoma, compared with other eye-conserving forms of primary treatment. Proton beam is also utilized for other malignant and benign tumors as primary, salvage, or adjuvant treatment with combined modality therapy. The physical characteristics of proton therapy allows for uniform dose distribution, minimal scatter, and sharp dose fall off making it an ideal therapy for ocular tumors in which critical structures lay in close proximity to the tumor. High radiation doses can be delivered to tumors with relative sparing of adjacent tissues from collateral damage. Proton beam therapy for ocular tumors has resulted in overall excellent chances for tumor control, ocular conservation, and visual preservation.
