    Eye melanoma:

    Elanoma is a type of cancer that develops in the cells that produce melanin — the pigment that gives skin its color. eyes also have melanin-producing cells and can develop melanoma. Eye melanoma is also called ocular melanoma. Most eye melanomas form in the part of the eye you can't see when looking in a mirror. This makes eye melanoma difficult to detect. In addition, eye melanoma typically doesn't cause early signs or symptoms.

    Symptoms:

    Eye melanoma may not cause signs and symptoms. When they do occur, signs and symptoms of eye melanoma can include: • A growing dark spot on the iris
    • A sensation of flashing lights
    • A change in the shape of the dark circle (pupil) at the center of eye
    • Poor or blurry vision in one eye
    • Loss of peripheral vision
    • Sensation of flashes and specks of dust in vision (floaters)

    Treatment:

    Surgery Operations used to treat eye melanoma include procedures to remove part of the eye or a procedure to remove the entire eye. Options may include:
    • Surgery to remove the melanoma and a small area of healthy tissue. Surgery to remove the melanoma and a band of healthy tissue that surrounds it may be an option for treating small melanomas. What procedure you'll undergo depends on the size and location of eye melanoma. For instance, surgery to remove a small melanoma affecting the iris is called iridectomy. Surgery to remove a melanoma in the choroid is called choroidectomy.
    • Surgery to remove the entire eye (enucleation).Enucleation is often used for large eye tumors. It may also be used if the tumor is causing eye pain. After the eye with melanoma is removed, an implant is inserted into the same position, and the muscles controlling movement of the eye are attached to the implant, which allows the implant to move. After you've had some time to heal, an artificial eye (prosthesis) is made. The front surface of new eye will be custom painted to match existing eye. Radiation therapy Radiation therapy uses high-powered energy beams, such as protons or gamma rays, to kill cancer cells. Radiation therapy is typically used for small to medium-sized eye melanomas. The radiation is usually delivered to the tumor by placing a radioactive plaque on eye, directly over the tumor in a procedure called brachytherapy. The plaque is held in place with temporary stitches. The plaque looks similar to a bottle cap and contains several radioactive seeds. The plaque remains in place for four to five days before it's removed. The radiation can also come from a machine that directs radiation, such as proton beams, to eye (external beam radiation or teletherapy). This type of radiation therapy is often administered over several days. Laser treatment Treatment that uses a laser to kill the melanoma cells may be an option in certain situations. One type of laser treatment, called thermotherapy, uses an infrared laser and is sometimes used in combination with radiation therapy. Cold treatments Extreme cold (cryotherapy) may be used to destroy melanoma cells in some small eye melanomas, but this treatment isn't commonly used.
