By definition, cancers grow their own blood supply in order to invade and grow in tissue where they don't belong. The blood vessels in ocular melanoma are more fragile than the normal blood supply of ocular tissues. Most melanomas do not bleed. However, bleeding is possible in melanomas that are about 3-4 mm or greater in thickness. Bleeding may occur: 1) at the time of diagnosis; 2) during surgical manipulations; 3) as the tumor dies after radiation treatment; 4) any time months and sometimes years after treatment during the evolution of the remaining scar tissue. Two important points: 1.) Bleeding does not increase the risk of metastasis. 2.) Bleeding is not a sign of tumor recurrence. When tumors do bleed, the blood stays in the eye, and may cause the following: no symptoms; reduced vision; elevated intraocular pressure by blocking the drainage of aqueous humor. Blood that doesn't clear on its own may need to be removed to improve vision and/or preserve the health of the eye.
