can a person have eye melanoma for 7 years and not know it?
i took a test 7 years ago that showed a block in my vision. i took the same test last week and the resaults were the same. my eye doc was worried it could be melanoma, but after seven years?

yes I believe so
sometimes a mole (or whatever analogous thing you had in your eye) can turn into a melanoma, but
sounds kind of strange.
You may experience no symptoms at all for melanoma of the eye. On the other hand, eye melanomas may cause light flashes, blurring or a dark spot in your vision.
What to watch for
A change in the color of the iris
A growing dark spot on the iris
A sensation of flashing lights
Poor or blurry vision in one eye
Loss of side (peripheral) vision in the affected eye
Floaters (spots or squiggles drifting in your field of vision)
A red and painful eye
