Uveal melanoma is the most common primary intraocular malignancy in adults. The disease overwhelmingly affects white populations. Other risk factors include fair skin, light iris color, ancestry from northern latitudes, and ocular/oculodermal melanocytosis. Historically, enucleation was the definitive treatment of uveal melanoma, but brachytherapy and proton beam irradiation are now the most commonly used treatment methods. However, there are still no effective therapies against metastatic uveal melanoma, which is almost always fatal. Continued advances in understanding of the molecular mechanisms of uveal melanoma will facilitate the identification of prognostic markers and therapeutic targets.
