If the tumor are large, the eyes should be appointed. If the eye is not raised, tumor can spread to the eye socket (orbita) and to other organs (through the blood vessel), causing death.

Melanoma symptoms

If the shape of melanoma is a black speck, basalinoma shaped like a stained wound located at the tip of the lid. This will not be lost just by giving antibiotics. while adenocarsinoma similar shapes a repeated bump that grows in one place. Cute in its shapes that make adenocarsinoma often being belittled. Adenocarsinoma classified to a ‘die hard’, often grow back after the surgery.

Adneksa last family member, carcinoma cells squamosa, identified as a small bump that is growth on the border in the skin and eyes. It can also appear between the black and white side of the eye. Existence that is known since the early, can be taken completely. But if kept, this tumor can penetrate to the back side of the eye. The troubling eye must be taken in whole.

Different to adneksa tumor family, the orbita tumor family have a habit, mass pile up at the back of the eyeball. So that one of the patients eye seen protruding out. If the tumor mass derived from the organ of it self, is called the mass rimer. But if it comes from other organs, the tumor appears to be rated in the Metastasis family. Orbita tigerish can develop quickly, between two month to one year since the first symptoms appear. This tumor also cause pain that extraordinary. To ensure the highest level of orbita tumor violence, the patient must undergo several examinations including CTScan. Meanwhile, to support the diagnosis, almost always to be done a biopsy (sample of tumor) first. from there will know what steps need to be carried out to cure the patient. Whether through surgery, through chemotherapy or radiation. Irradiation is done if the tumor is the distribution of local (only in the eye area), whereas chemotherapy was performed if the tumor has spread to other body parts.

Patients with violent Orbita who choose surgery way, must think in long-term. Because this tumor removal process will be very extreme. Nearly all the eyes will be lifted. Start from eyelid, eyeball, to all contained within the back of the ball. So that left only the bones, the bones around the eye only. Utilizing of the imitation eye, may be allowed, at least two months after the surgery is completed.

Metastasis eye tumor

This type of tumor is not caused from the eye, but the result of other organs in the body such as brain tumor, kidney, liver prostate, breast and bowel.

The manifestation of Metastasis tumor is generally the same as the orbita, so the taking care is similar. as a note, if the tumor is the eye (Metastasis), that means the main tumor (breast, liver etc) is located on the end of the stadium.

Outside the three main families of tumor, there is still another type of eyeball tumor. One is retino blastoma. Symptoms are, eyes shine like cat eyes in the night. In the early stages, this tumor can be taken complete with laser rays eye or lifting the ball without the lid. But if it became too violent, there is no way other than chemotherapy.

The eye tumor was not only attacks the eyes, but also other organs. All the malignant tumor has spread of a serious power. Basalioma is become the only one that is not spread, although still cause a very serious local destruction.

Dr Ian Yeo Yew San, ophthalmologist who served as a consultant in the Singapore National Eye Center who joined the service in the health tourism, FlyFreeForHealth, said, “When exposed to diabetes, the body does not use the sugar (glucose) properly. If blood sugar is too high, the natural eye lens will increase so that the view-blur. Later, the amount of sugar that is too much can damage the small blood vessel which gives nutrition to the retina (capillary). So retinopathy diabetic will arise. ”

Sign and symptoms

At the initial stage, retinopathy diabetic have no symptoms or only cause mild eye disturbances. However, the long run, can culminate in blindness. Retinopathy diabetic usually affect both eyes.

Symptoms of diabetic retinopathy include:
- spots float in my vision
- blurred vision or does not focus
- Line-or dark red lines that impede the vision
- Difficult to see at night
- Vision is lost / blind

Vetting / Screening for Diabetic Retinopathy

As part of the eye test, your doctor will make an image of the retina called fluorescein angiography. First, the doctor will increase pupil and then take it picture. Then, a special liquid color will be injected intravenously into the arm. Other photos will be taken along with the liquid color that flows in and start to circulates in the eyes. Doctors will use the photos to see where the vein is closed, damaged or leaking.

Doctors usually will also ask that you undergo a Optical Coherence Tomography (Oct) test. The test produces images of the retina cross-examination that may indicate thickness retina and to determine whether the fluid was leaking into the retina network.

Dr Yeo suggest to the patient to control diabetes with diet and medication to slow or prevent the development of diabetic retinopathy or other complications. It is a good idea to do eye examination once a year.
