Eye Cancer
is a disease that occurs due to the cells in the eye tissue grow uncontrollably
and its growth can be spread to other areas. At the time it grows and spreads,
the cancer cells can damage normal cells around it. Eye cancer can occur in
three main parts, namely:
•
eyeball (globe). Part of the eyeball consisting of
various tissues and fluids that make up the sensory system vision. Three layers
of tissue that make up the eyeballs are:
Sklera is white, the loudest, and the
farthest. On the front of the eye, there is a clear colored sclera called the
cornea of the eye.
The
retina is the innermost part of the eye
which is composed of nerve cells that are sensitive to light.
•
Uvea is
the eyeball between the retina and sclera.
Uvea consists of iris that gives color to the eye and forms the pupils, the
choroid which serves to provide nutrition for eyes and pigment-producing cells
also contain (melanocytes), as well as the salaries
agency set the lens of the eye.
•
Orbita. The orbit of the eye is a range that surrounds the
eyeball tissue, including muscles,
control the movement of the eyeball.
•
Spy Gear. Parts accessories or additional parts are adnexa
on the eye as the eyebrows, tear gland, conjunctiva, eyelids, and eyelashes.
Eye
cancer can begin from the eye or from other organs that the cancer cells spread
to his part of the eye. Cancer of the eye that comes from a part of the eye
called the primary cancer of the eye. While cancer of the eye that originated
in other organs is called secondary cancer of the eye. Eye cancer is a rare
disease.
Types Of Eye Cancer
Based
on the type of network, cancer of the eye can be divided into:
•
Intraocular Melanoma. This type of cancer is melanoma
that occurs on the network of the
eyeball. Intraocular Melanoma is a type of eye cancer most frequently occurs,
but still rare compared with the skin cancer melanoma. Cancer types of melanoma
occur in pigment-producing cells or melanocytes located in tissues of the uvea. The choroid is the site of a growing
tumor that is most often. In addition to the choroid, intraocular melanoma
first can be detected on the network. Melanoma is cancer on the iris grows slowly and rarely spreads to other organs.
•
Intraocular Lymphoma. Called intraocular Lymphoma,
because this cancer occurs in cells in the lymph nodes in the eye. Intraocular
Lymphoma that arises often included the non-Hodgkin's lymphoma. Most of the
intraocular Lymphoma sufferers have problems on the system of funny, for example, is suffering from AIDS.
Intraocular Lymphoma also frequently appeared together with the lymphoma in
central nervous systems called primary central nervous system lymphoma (PCNSL).
•
Retinoblastoma. Retinoblastoma is a cancer of the eye
that specifically attack the children. Arising out of the occurrence of the
retinoblastoma gene mutation on the retina causing retinal cells to divide rapidly and spread to the eyes and other body parts. Retinoblastoma can occur
in one or both eyes. If it happens on the second eye, retinoblastoma can be
detected even before the age of 1 year. If detected early, retinoblastoma can
be treated very well and has a high cure rate. In addition to retinoblastoma, a
cancer of the eye is the second medulloepithelioma on eyeballs, although very
rare.
In
addition to these three types of eye cancer that occurs in the eyeball, eye
cancer can also occur in orbit and adnexa eyes. Some types of cancer in the eye adnexa and orbital
network include:
• Cancer of the eyelids. Is a variant of skin
cancer. Basal cell carcinoma may be a or squamous cell carcinoma.
• Cancer of the orbit. Cancer
that occurs in the muscles of the eyeball movers and connective tissue
surrounding eyeball (rhabdomyosarcoma).
• Melanoma conjunctiva. Conjunctiva is a
membrane that lines the eyelids and eyeballs. Conjunctiva melanoma looks like a
black stain on the eyes.
•
Glandular Tumor tears.
