Eye Cancer (Eye Melanoma): Symptoms, Causes, Diagnosis and Treatment.

Description:

Melanoma is a cancer form which grows in the cells that make melanin- the pigment that gives your skin its color. Though melanoma typically affects the skin, it can also spread to the eye. Eye melanoma is also known as ocular melanoma. Melanoma is the most common type of eye tumor in adults however; melanoma of the eye alone is rare.

Title: Eye Cancer (Eye Melanoma): Symptoms, Causes, Diagnosis and Treatment.

  • Eye Cancer (Eye Melanoma)

Introduction to Eye Cancer
  • Melanoma is a cancer form which grows in the
    cells that make melanin- the pigment that gives
    your skin its color. Though melanoma typically
    affects the skin, it can also spread to the eye.
    Eye melanoma is also known as ocular
    melanoma. Melanoma is the most common type of eye
    tumor in adults however, melanoma of the eye
    alone is rare.Eye melanoma is difficult to
    identify because it forms in the part of the eye
    you can't see when looking in a mirror. Moreover,
    this type of cancer typically doesn't cause early
    signs or symptoms.

Symptoms of Eye Cancer
  • Eye melanoma may not show signs and symptoms at
    the beginning. But when they appear, they may
    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 your eye
  • Poor or blurry vision in one eye
  • Loss of peripheral vision
  • Sensation of flashes and specs of dust in your
    vision (floaters)
  • Bulging eyes

4
Causes of Eye Cancer
  • It's not clear what causes eye melanoma, also
    called ocular melanoma. Doctors know that eye
    melanoma occurs when errors develop in the DNA of
    healthy eye cells. The DNA errors tell the cells
    to grow and multiply out of control, so the
    mutated cells go on living when they would
    normally die. The mutated cells accumulate in the
    eye and form an eye melanoma.

5
Diagnosis of Eye Cancer
  • Eye examination Your eye doctor will examine the
    outside of your eye looking for enlarged blood
    vessels that can specify a tumor inside your eye.
    With the help of instruments, he/she will look
    inside your eye.
  • Eye ultrasound An eye ultrasound uses
    high-frequency sound waves from a transducer to
    produce images of your eye.
  • Angiogram It is a procedure where a colored dye
    is injected into a vein in your arm. The dye
    travels to the blood vessels in your eye. A
    camera with special filters to detect the dye
    takes pictures every few seconds.
  • Removing a sample of suspicious tissue for
    testing In some cases, your eye doctor may
    propose a procedure to remove a sample of tissue
    (biopsy) from your eye.

Treatment of Eye Cancer
  • Treatment for malignant melanoma of the eye will
    depend on the specific type of tumor that you
    have. If the tumor is small and is not growing
    rapidly, your eye specialist may not recommend
    treatment. However, he/she will keep an eye on
    the growth of the tumor. If your tumor is large
    or has the potential to spread, your doctor may
    recommend more belligerent treatment. There are
    several options
  • Surgery to remove the eye
  • Radiation therapy to kill the cancer cells inside
    the eye
  • Laser therapy
  • Extreme cold may be used to destroy melanoma
    cells in some small eye melanomas

7
Preventions of Eye Cancer
  • We know there is a link between sunlight and
    melanomas of the skin, and there are things you
    can do that might reduce your risk of these
    cancers, including limiting your exposure to
    intense sunlight, covering up with protective
    hats and clothing, and using sunscreen. Wearing
    UV-protected sunglasses when outside in strong
    sunlight. Wrap-around sunglasses with 99 to 100
    UVA and UVB absorption provide the best
    protection for the eyes and the surrounding skin.
    This might help reduce the risk of developing
    cancers of the skin around the eyes. The link
    between sunlight and eye melanomas is not proven,
    but some doctors think that sunglasses might also
    reduce eye melanoma risk.

8
Complications of Eye Cancer
  • Vision loss. Large eye melanomas often cause
    vision loss in the affected eye and can cause
    complications, such as retinal detachment, that
    also cause vision loss.
  • Increasing pressure within the eye (glaucoma)
  • Eye melanoma that spreads beyond the eye.

9
Risk Factors of Eye Cancer
  • Light eye color. People with blue eyes or green
    eyes have a greater risk of melanoma of the eye.
  • Being white. White people have a greater risk of
    eye melanoma than do people of other races.
  • Increasing age. The risk of eye melanoma
    increases with age.
  • Certain inherited skin disorders. A condition
    called dysplastic nevus syndrome, which causes
    abnormal moles, may increase your risk of
    developing melanoma on your skin and in your
  • Exposure to ultraviolet (UV) light. There's some
    evidence that exposure to UV light, such as light
    from the sun or from tanning beds, may increase
    the risk of eye melanoma.
