Can you see the optic nerve on an eye exam?
During an eye exam, your doctor can perform an ophthalmoscopy to easily view the head of the optic nerve, called the optic disc. This part of the optic nerve is an extension of the brain, making it the only part of the brain that can be visible from the outside.
Does a CT scan show the optic nerve?
Although the CT scan may detect drusen of the optic nerve head and at the same time rule out increased intracranial pressure owing to a mass lesion, MRI is clearly more sensitive for diagnosing intracranial abnormalities.
Can a doctor see your optic nerve?
The eye is a beautiful organ, and it is the only place in the human body where a doctor can see a part of the central nervous system, the optic nerve. The observation of that nerve is a crucial part of a comprehensive eye examination.
How can you tell if your optic nerve is damaged?
Symptoms

- Vision loss in one eye. Most people have at least some temporary reduction in vision, but the extent of loss varies.
- Visual field loss.
- Loss of color vision.
- Flashing lights.
Can an MRI detect optic neuritis?
Testing helps to exclude other diagnoses and evaluates the likelihood of other diseases. A magnetic resonance imaging (MRI) study of the brain and orbits (the eye sockets) with gadolinium contrast may confirm the diagnosis of acute demyelinating optic neuritis.
