Definition: A cancer of the eye that develops in the choroid, the spongelike membrane that lies between the sclera (the white of the eye) and the retina.

Choroidal melanoma is a rare form of cancer, but is the most common cancer that develops in the eye. A choroidal melanoma tumor may grow for some time before it is discovered, as it causes no symptoms in its early stages. When symptoms do occur, they may include blurry vision, increased floaters, flashing lights, or eye pain.

Also Known As: eye cancer
