Optic Glioma Diagnosis & Tests
A neurologic examination reveals a loss of vision in one or both eyes. There may be changes in the optic nerve, including swelling or scarring of the nerve or paleness and atrophy of the optic disk.
There may be extension of the tumor into deeper locations of the brain and signs of increased pressure within the brain (intracranial pressure). There may be signs of NF1.
- A head CT scan or MRI of the head confirms the diagnosis and the exact location of the tumor.
-
Cerebral angiography is not often necessary, but if used, it shows a space-occupying mass which is not vascular.
- Visual field tests can help determine how invasive the tumor is
- An examination of tissue removed from the tumor during surgery or CT scan-guided biopsy is used to confirm the exact type of tumor.
