Intraocular metastasis is the most common intraocular tumor. The most common primary tumor site is the lung in men and breast in women . In the majority of cases, intraocular metastasis is limited to choroid. Other ocular structures, like the vitreous, optic nerve, and iris, may also be involved and rarely, a tumor may metastasize to the retina.
