What is the gliom of optical nerve?
Optical nerve glioma is a tumor that appears on a structure that carries the visual input from the eye to the brain. Most gliomas, especially those found in young children, are benign and easily treated. Some tumors in adults, however, rapidly change cancer, grow aggressively and spread to other parts of the brain and body. Both forms of optical nerve glioma may result in partial or overall loss of vision, as well as headaches and eye scorpion. Small and benign tumors can often be surgically removed, although it may be necessary to treat cancer by a combination of chemotherapy and radiation. Some studies suggest that genetics plays a role in their development because many patients have a familial history of nerve tissue tumors. Most benign tumors grow very slowly and may not cause any physical symptoms for several months or years. It is possible for a child to have gliomas on each eye, although most patients have singular -free. Malignant growth tends to develop rapidly, become cancerousAnd it begins to spread within a few months of their foundation.
An individual suffering from an optical nerve glioma is likely to experience a certain degree of vision damage. The loss of peripheral vision is the most common, but advanced glioma can affect all aspects of sight. Depending on how much pressure the tumor puts on the optical nerve, the affected eye can burst out or pluck uncontrollably. Some patients experience generalized symptoms of fatigue, headaches, nausea and cognitive damage.
When a primary care doctor suspects the glioma of the optical nerve, he usually refers to a patient to a neurologist to obtain an official diagnosis. A neurologist can perform computer tomography (CT) and magnetic resonance imaging tests (MRI) on the eyes and brain, looking for signs of unusual materials and scarring. Ócce is discovered a tumor, the doctor may decide to extract a small tissue sample for laboratory andpoured. Tests can reveal whether matter is cancer, benign or sign of another serious brain disease.
After diagnosis, a neurologist can determine the best treatment. Surgery can usually be performed on a small optical nerve gliom to combine the weight and relieve the pressure on the nerve. If surgery is unsuccessful or cancer has already begun, the patient may be subjected to several rounds of radiation or chemotherapy. Patients are usually prescribed painkillers and instructed to rest as much as possible during recovery. Treatment of benign tumors often leads to a complete recovery of vision, although malignant problems are likely to lead to some loss of vision.
