Symptoms of Melanoma in Eye
Symptoms of Melanoma in Eye Melanoma is a type of cancer that develops in cells that produce melanin — the pigment that gives your skin its color. Their eyes also have melanin-producing cells and can develop melanoma. The eye melanoma is also called ocular melanoma.
Most eye melanomas are formed in the part of the eye that is not seen when looking into the mirror. This makes the eye melanoma difficult to detect. In addition, eye melanoma typically does not cause early signs or symptoms. The treatment is possible for eye melanoma. Treatment for some small eye melanoma can not disturb your eyesight. However, the treatment of large eye melanomas typically causes a vision loss.
Eye melanoma cannot cause any signs or symptoms. If they occur, signs and symptoms of eye melanoma may include:
- A growing dark spot on the iris
- A sense of flashing lights
- A change in the shape of the Dark Circle (pupil) in the center of the eye
- Poor or blurred eyesight on one eye
- Loss of peripheral vision
- Sensation of lightning and dust stains in your eyesight (swimmer)
Eye melanoma (ocular melanoma)-origin
Many people are confused by the melanomaspekt of this type of eye cancer, since melanoma is most often associated with the skin. Melanomas originate from melanocytes, cells containing dark pigment (melanin) that define skin color. Melanocytes are not just on the skin – they can be found in the hair, eyes and lining of some organs.
The eye melanoma usually begins in the middle layer of the eye known as Uvea. This is the layer of blood vessels in the bone. The outer layer is the sclera (The thick white part) and the inner layer is the retina (where the rods and cones, which are the sensory part of the eye, absorb signals that are sent to the brain.) Sometimes it also comes to melanoma on the konkoktiva or eyelid.
This cancer is most common among older people and spikes at the age of about 70. Men are more common than women. Eye melanomas constitute about 5% of melanoma.
What causes ocular melanoma?
Like many other types of cancer, we are not quite sure what causes the eye melanoma, but there is a suspicion that it is related to exposure to the sun’s ultraviolet rays. However, this theory has yet to be proven.
Although the cause of eye melanoma has not yet been clarified, the researchers have identified risk factors for the disease. Risk factors for eye melanoma are similar to risk factors for the melanoma of the skin and include:
- Fair skinned or with a light hair color and eye color (blue or green eyes)
- Longer sun exposure or tanning beds
- The ability to Tan
- Caucasian Race
- With Dysplastischem nevus syndrome, a condition that causes abnormal mules
- Abnormal pigmentation of eyelid or Uvea
- With Oculodermale melanozytose, a rare disorder that causes increased and abnormal pigmentation of the eye and skin around the eye
The researchers learn much more about cancer genetics and melanoma and it is believed that 55% of their own risk for melanoma is due to genetic factors.
Symptoms of eye melanoma
Especially in the early stages, there are sometimes no noticeable symptoms of eye melanoma. In these cases, the melanoma of the eye is usually diagnosed by a routine eye screening by an optician or Opthalmologen. Eye Melanoma symptoms are:
- Blurred vision on one eye
- Floats (small “floating” spots in your field of light)
- Change of iris color or dark spot on the iris
- Change in the form of the pupil
- See Flashing lights
- Red and/or painful eye
- Wugenden Eye
- Loss of peripheral vision or loss of sight
- Because of the most common locations of these tumors, people are usually not able to detect the cancer itself-that is, they
- are usually not seen in the mirror.
Diagnosis of eye melanoma
In contrast to other types of cancer, a biopsy is usually not necessary for most cases of eye melanoma. One of the first tests that most people have is called a ophthalmoscope, which uses a special leeway to get a deep look at the eye. It is similar to the tool your optician or doctor uses to look at your eye. It is non-invasive and is painless and done after your ophthalmologist first dilutes your eyes.
An ultrasound can also be done to see the eye and surrounding structures. Numbing drops are given before the scan to avoid inconvenience. You may be asked to look in different directions to allow different angles. Eye Ultrageräusche usually take about 15 minutes or less.
Other tests, such as an MRI or CT scan, can be performed when it is suspected that the cancer has spread over the eye. The liver is a common place of metastases for eye cancer. This list shows where melanoma often spreads.
Treatment of eye melanoma
The treatment of the eye melanoma is based on which part of the eye is affected and whether it is metastasized to other parts of the body.
Surgery is a method of treating melanoma of the eye. The removal of the eye (enucleation) may be necessary in some cases of large tumors if other treatment methods are not suitable. In most cases, an artificial eye can occur. Prosthetic eyes are much more realistic today than they used to be. They are created by talented, trained individuals called ocularist. Usually it takes between 4 and 6 appointments to be prepared for a prosthetic eye and place it. Quality and artistic talent are two important features to consider when choosing a ocularist.
Symptoms of Melanoma in Eye
Radiation therapy is also a common treatment for eye melanoma. It can be the only treatment or performed after surgery. There are two types of radiation therapy: externally and internally. Both use certain types of energy to disrupt the activity of cancer cells in order to eliminate them and prevent them from being subjected to cell division.
- The external radiation provides radiation from a specialized machine that adheres to the tumor location externally. This radiation method is specific and limits the damage to the surrounding tissue.
- The internal radiation (brachytherapy), often referred to as plaque therapy in the treatment of the eye melanoma, uses a radioactive “semen” or “plaque” implanted near the tumor site to provide therapy. Usually it remains implanted for about 7 days and is then removed. This is the most common type of radiation therapy used for eye melanoma.
Radiation therapy is effective against eye melanoma, but does not occur without side effects. Red, dry eyes are a common side effect. Cataracts sometimes result from therapy, but an operation may be an option to remove them. Eyelash loss and shortening can also occur. Less often, radiation therapy can cause optical nerve damage, glaucoma and abnormal blood vessels in the retina.
