Metastasis to the contralateral orbital cavity in uveal melanoma (UM) is extremely rare.1 Only 8 cases of such metastases have been reported, and none included mutational analysis. For the first time, to our knowledge, we report data from a mutational analysis of GNAQ and GNA11 supporting the diagnosis of a single metastatic tumor.
