Optic nerve gliomas occur in or around the nerves that send messages from the eyes to the brain. They are frequently found in persons who have neurofibromatosis, a neurocutaneous syndromic condition a child is born with that makes him/her more likely to develop tumors in the brain. Dr Raos hospital in Guntur, Andhra Pradesh offers the best neurosurgery treatment.

People with optic nerve gliomas may experience loss of vision, as well as hormone problems, since these tumors are usually located at the base of the brain where hormonal control is located. These are typically difficult to treat because of the surrounding sensitive brain structures.

What is an optic nerve glioma?

The brain tumor originating from the optical apparatus or optic nerve is called optic nerve glioma. They are located in the optic chiasm, the junction of the left and right optic nerves. They are low-grade and don’t grow often. It is mainly seen in kids and is rarely seen over the age of 20. It is commonly associated with neurofibromatosis type 1, or NF1.

What are the symptoms of an optic nerve glioma?

Compression of the nerve and brain tissue causes the symptoms and include. 

• vision disturbances
• nausea and vomiting
• headaches
• balance problems
• daytime sleepiness
• growth delays
• memory impairment
• involuntary eye movements
• loss of appetite

Hormone problems are secondary to the compression of the pituitary stalk and hypothalamus, the base of the brain.

How is an optic nerve glioma diagnosed?

A good clinical history, neurological examination with decreased vision, and increased pressure in the brain often lead to clinical diagnosis. Imaging studies include CT scans and MRI brain plain and contrast.

How is an optic nerve glioma treated?

Management depends on the multidisciplinary approach. Neurosurgeons, radiation oncologists, neurooncologist, and neuro-ophthalmologists are the typical crew. Radiation therapy or surgery are two possible ways. 

Surgery is an option if the tumor can be eradicated or to relieve the pressure in the brain. Radiation therapy is another modality used as an adjunct to surgery or as a primary modality.

Chemotherapy

Corticosteroids 

After treatment

Long-term side effects may occur after treatment, including learning disabilities, Cognitive difficulties, and impairments in growth secondary to radiation or chemo. Talk to Dr. Rao regarding this, and he will suggest how to fight this tumor.
