Melanoma is a type of cancer that develops in the cells that produce melanin. Melanin is the pigment that gives skin color. Eyes also have cells that produce melanin and can develop melanoma. Eye melanoma is also called ocular melanoma.
Ocular melanoma is often not visible when the mirror. This makes it difficult to detectocular melanoma. In addition, ocular melanomas usually do not cause early signs or symptoms.
Treatment for some small ocular melanoma may not impair vision. However, treatment for melanoma of the eye usually causes some loss of vision.
It is unclear what causes ocular melanoma. Doctors know that ocular melanoma develops when an error occurs in the DNA of cells of a healthy eye. Errors DNA tells cells to grow and multiply out of control. So that the mutated cells continue to live as they normally would die.
Mutated cells to accumulate in the eye and ocular melanoma form. Ocular melanoma most often develops in the cells of uvea, the layer of the eye blood vessels are sandwiched between the retina, a thin layer of tissue lining the back wall of the eyeball, and the whites of the eyes (sclera). Ocular melanoma can occur in the front of the uvea (iris and ciliary body) or in the back of the uvea (choroid layer).
Ocular melanoma can also occur in the outermost layer at the front of the eye (conjunctiva), in a socket that surrounds the eyeball and eyelid, although very rare type of ocular melanoma.
Ocular melanoma may not cause signs and symptoms. Signs and symptoms of ocular melanoma may include:
1. Dark areas grew in slices
2. The sensation of flashing lights
3. Changes in the form of dark circle in the center of the eye
4. Vision in one eye
5. Loss of vision in the affected eye
Ocular melanoma treatment options will depend on the location and size of melanoma, as well as overall patient health. If small and not developing melanoma, the patient maychoose to wait and observe the development of growth.
If the melanoma is growing or causing complications, it may choose to undergo treatmentat that time. Several treatment options for ocular melanoma, among others:
2. radiation therapy
