Eye cancer: melanoma and retinoblastoma

Malignant melanoma is related to cancer cells that develop in tissues of the eyes, the iris, choroids (blood vessels and ciliary body) and the eye muscles.

As with retinoblastoma, it is a cancer that develops in the retina. The disease may be bilateral or touch one of the two eyes.

What are the risk factors for cancers of the eye?

The risk of developing melanoma increases in the presence of a genetic predisposition.

The prolonged exposure to sunlight and certain chemicals industrial (PCBs) are also risk factors for melanoma of the eye. Skin and light hair are aggravating factors, like blue or green eyes.

Note that often, cancers of the eye are called secondary cancers, that is to say that they are metastases from other cancers that have spread to tissues of the eye.

What are the symptoms of melanoma in the eye?

1. Gradual loss of vision.
2. Flashes of light (flash).
3. Redness.
4. Spots in the visual field , “floaters”.
5. Tendency of the eyes to converge on one point.
6. Excrescence on the surface of the eye or protrusion of the globe.
These symptoms require a consultation with an ophthalmologist. It shall review clinical eye and a dilated pupil. In case of suspicion of a tumor in the eye, ocular ultrasound, CT or MRI will help determine the location of the tumor and its characteristics.

What are the symptoms of retinoblastoma?

Strabismus and whiteness of the pupil are the most easily recognizable symptoms of retinoblastoma, which should quickly lead them to consult.

# E # A leukocoria means a whiteness of the pupil or a white reflection visible in certain lights that flash or in certain directions of gaze. This reflection in the eye of a child sometimes be spotted on a photo.

Early diagnosis and treatment can limit the damage of the eye (initiated earlier, current treatments can cure 95% of children). Therefore if a family history of retinoblastoma, the child must be examined shortly after birth by an ophthalmologist.

What are the treatment of cancers of the eye?

Radiotherapy, by destroying cells cancer while preserving the view, deals with many melanoma and retinoblastoma.
Laser treatments are also used for small tumors.
Cry therapy is itself a technique aimed at destroying cancer cells by the cold .
The surgery is reserved for tumors of size too large and very advanced, can not be handled by previous techniques called conservative. It is based on enucleation (removal of the eyeball).
Finally, if risk of metastases, chemotherapy is sometimes proposed: it prevents the eye cancer from spreading to other body tissues.
