Should I be concerned about a black/very dark vein in white of my eye?
Veins on the surface of the eye can vary in appearance and size. Veins contain blood without oxygen, so are somewhat blue in color and in certain lights can appear very dark, almost black. Venous patterns like this, if long standing, are usually benign and nothing to worry about. If this appeared suddenly, especially if the vision is impacted, then an ophthalmologist should be consulted.
