Neuro Ophthalmology

Neuro-ophthalmology focuses on conditions caused by brain or systemic abnormalities that result in visual disturbances.

What is Neuro-Ophthalmology?

Neuro-ophthalmology is concerned with the neurological problems that affect your eyes. Half of the human brain is utilized for vision-related activities, including sight and moving the eyes. If the optic nerve is not functioning properly it might lead to irreparable vision loss. However, the Neuro-ophthalmology, a subspecialty of both neurology and ophthalmology, requires specific training and expertise in issues of the eye, brain, nerves, and muscles. The eye consultant also known as Neuro-ophthalmologist deals with visual issues that are related to the nervous system; that is, visual problems that don’t originate from the eyes themselves.

What are the common symptoms that require attention?

The typical symptoms of a neuro-ophthalmological problem include:

  • Sudden decrease or loss of vision
  • Sudden transient loss of vision (called transient ischemic attack or eye stroke)
  • Visual hallucinations
  • Double vision or diplopia
  • Intractable headaches
  • Pupillary abnormalities (sluggish reaction, the difference in size of the pupils)
  • Sudden onset of difficulties in identifying colors
  • Inability to tolerate bright light
  • Visual Field Defects
  • Squint or strabismus

What are the types of neuro-ophthalmic eye diseases?

Optic Neuritis

In this condition, there is a sudden onset loss or decrease in vision power due to inflammation of the optic nerve. Optic neuritis is often associated with Multiple Sclerosis (MS). It is mostly due to an infection or an autoimmune response.


Papilledema is described as the swelling of the optic nerve head (the part of the optic nerve which can specifically be seen by your eye specialist during a retinal evolution) because of increased pressure from inside the brain. It might be because of tumors, infections like meningitis, encephalitis, etc.

Toxic or Nutritional Optic Neuropathy

Toxic substances found in tobacco & alcohol damages our optic nerve. Lack of nutrients and deficiency of vitamin B-complex and folic acid as well lead to the damage of optic nerve.

What are the common tests for diagnosis of neuro-ophthalmic eye conditions?

Some of the common tests include:

  • Orthoptic evaluation
  • Evaluation of ocular movements
  • Diplopia charting
  • Neurological visual fields screening
  • Optical coherence tomography of the optic nerve head
  • Evaluation of contrast sensitivity and color vision
  • Imaging studies including CT scan, MRI and MR venogram
  • Lumbar puncture

Treatment for neuro-ophthalmic eye conditions

Your eye expert will be in a perfect position to detect an optic nerve issue during an eye examination. A brain CT scan or an MRI is then regularly done to evaluate whether there is associated damage in the brain too. While a few conditions can be treated with oral medications and injections, others may require a medical procedure. Some of the basic treatment options would be:

Optic Neuritis: Antibiotics and corticosteroids are used to flush out the infection or suppress the immune disorders from causing further damage.

Papilloedema: To reduce the pressure inside the skull medications are used. If the increased pressure is due to a tumorous growth it might require a brain surgery

Nutritional Optic Neuropathy: Lifestyle changes are being recommended and vitamin injections are prescribed.

Diabetic Retinopathy: Since the underlying cause is diabetes, treating the diabetes is essential before it causes further damages to the nerve and other blood vessels.
