The choroid layer is the most likely location of melanoma in the eye.
The cancer may only be in the eye, or it may spread (metastasize) to another location in the body, most commonly the liver. Melanoma can also begin on the skin or other organs in the body and spread to the eye.
Melanoma is the most common type of eye tumor in adults. Even so, primary melanoma of the eye is rare.
Excessive exposure to sunlight is an important risk factor. The occurrence of melanoma has greatly increased in recent decades. Fair-skinned and blue-eyed people are most often affected.
The outcome for melanoma of the eye depends on the size of the cancer at the time of diagnosis. Most patients will survive at least 5 years from the time of diagnosis if the cancer has not spread outside the eye.
If the cancer has spread outside the eye, the chance of survival is much lower.
Call for an appointment with your health care provider if you have symptoms of melanoma of the eye.
The most important way to prevent eye melanoma is to avoid excessive exposure to sunlight, especially between 10 a.m. and 2 p.m., when the sun's rays are most intense. Wear sunglasses, and be sure they have ultraviolet protection.
