Presumed metastasis of choroidal melanoma to the contralateral choroid.

Purpose: To report a case of choroidal melanoma metastasizing to contralateral choroid along with systemic metastasis.

Methods: This is a retrospective study of a case of a 52-year-old man who was found to have a choroidal lesion in the left eye temporal to fovea. The ultrasound and angiographic findings were suggestive of choroidal melanoma, which prompted enucleation of the eye.

Results: After approximately 74 months, the patient noticed decreased vision in the contralateral (right) eye. Examination revealed a nonpigmented mass lesion approximately two disk diameters in size superotemporal to fovea, and the patient was found to have multiple secondary tumors in the abdomen and liver.

Conclusion: The development of choroidal metastases from a contralateral choroidal melanoma is of ophthalmic interest and seems to be unique.
