Uveal melanoma is the most common intraocular malignancy and arises from melanocytes in the choroid, ciliary body, or iris. Radiotherapy is the mainstay of therapy for most patients with localized uveal melanoma. Another RT technique used in the treatment of uveal melanomas is charged-particle radiotherapy. Photodynamic therapy is based on the selective destruction of cancer cells or pathological vessels. High-Intensity Focused Ultrasound (HIFU) is a promising technology of thermal destruction of solid tumors located deep under the skin. The principle of operation is based on the heating of a tumor. Sonodynamic therapy (SDT) induces the reactive oxygen species and kills cancer cells. Electroporation applied in vivo delivers drugs or genetic material from the intercellular space to cells. Iontophoresis is a technique in which using electric current increases the biodistribution of drugs in the eyeball. Transcorneal iontophoresis has been shown to increase the local concentration of antibacterial and antifungal drugs, steroids, DNA, and RNA molecules. Theranosticsincorporates diagnostic imaging and therapy. Although no theranostic markers have been developed specifically for uveal melanoma, some NPs have already found use in ophthalmology. UM presents an unmet clinical need. Novel eye-preserving therapeutic approaches for the localized disease are needed.
