When should you visit your Neuro-Ophthalmologist?
Neuro-Ophthalmology is a super specialty that merges the fields of neurology and ophthalmology. Neuro-ophthalmologists are responsible for the diagnosis and management of complex systemic diseases of the nervous system that affect vision, eye movements and alignment, as well as pupillary reflexes.
Your eye doctor will usually suggest you visit an expert in Neuro-Ophthalmology after a comprehensive eye examination, in case you need special care. Often, the symptoms that prompt such a referral include those associated with optic nerve disease or diseases of the visual pathway (the nervous system component that connects the eyes to the brain).

Causes of Neuro-Ophthalmic Disorders
The origin of neuro-ophthalmic disorders can be traced to nervous issues in the brain, which affect ocular movement and vision. Considering this, some common disorders are autoimmune diseases, tumours, infections, and vascular issues.
Here are some of the most common causes of neuro-opthalmic disorders:
Conditions such as multiple sclerosis (MS), lupus, and myasthenia gravis can lead to inflammation and cause damage to the optic nerve.
Infections of viral or bacterial origin can lead
Reduction in the flow of blood due to preexisting conditions like diabetes, giant cell arteritis, and hypertension can lead to loss of vision.
Trauma from brain surgery can also lead to loss of vision.
Common Symptoms that Require Attention
- 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 (especially adult onset)
Types of Eye Diseases treated by a Neuro-Ophthalmologist
The common eye diseases that require attention from a neuro-ophthalmologist include:
Optic Neuritis
It is a condition which presents as a sudden onset loss or decrease in vision due to inflammation of the optic nerve. It can be due to an infection, or an autoimmune response. Optic neuritis is often associated with Multiple Sclerosis(MS).
Papilledema
Papilledema is characterized by the swelling of the optic nerve head (the part of the optic nerve which can directly be seen by your eye doctor during a retinal evaluation) due to increased pressure from inside the brain. It may be due to tumors, infections like meningitis, encephalitis, etc.
Toxic or Nutritional Optic Neuropathy
The optic nerve may be damaged due to toxic substances found in tobacco & alcohol. In fact, the optic nerve damage is often due to lack of nutrients and deficiency of vitamin B-complex and folic acid as well. These diseases also present as decreased vision.
Squint or Strabismus
A misalignment of the eye, especially when sudden in onset, and associated with double vision is often due to paralysis of one or more of the small muscles of the eye, and is called paralytic strabismus. The eye shows limitations of ocular movement as well.
Common Tests for Diagnosis & Management of Neuro-Ophthalmology Diseases
A comprehensive eye examination is always the mainstay of the disease diagnosis, according to an ophthalmology specialist in Kolkata. In addition to this, your doctor will also advise one or more of these special tests to help plan your treatment. These 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 colour vision
- Imaging studies including CT scan, MRI and MR venogram
- Lumbar puncture

Medical Management
The medications, as suggested by Dr. Prosenjit Mondal, the best Neuro Ophthalmology Specialist in Kolkata, are:
Immunosuppressants: Used to treat conditions that lead to inflammation, such as optic neuritis, or certain kinds of autoimmune disorders.
Anticoagulants: It is usually suggested for treating conditions affecting the optic nerve.
Antibiotics: Suggested by the doctor only in cases of infections
Therapy and Rehab
Vision Therapy: This involves curated exercises to improve the coordination of ocular movements.
Visual Aids: Prism lenses can be used to manage cases of double vision. They can assist in vision correction.
Rehabilitation Services: Occupational therapy and low vision services can assist patients dealing with permanent loss of vision.
Surgical Interventions
Repairing Structural Damage: Surgical repair can be a solution for nerve damage and palsies.
Nerve Decompression: Surgery is also a good option for lessening the intraocular pressure on the optic nerve. It is also used to deal with brain tumours and structural abnormalities
