All the information you need on Neuro-Ophthalmology
Neuro-ophthalmology is a super speciality that deals with neurological problems associated with the eyes. Since our brain plays an important role in visual activities, it is understandable that any issue coming in the nerve pathway between the brain and the eyes can result in progressive and irreversible loss. Hence, it requires prompt action and treatment.
Optic nerves transmit electrical impulses from the retina to the brain. Any dysfunction with the optic nerve might lead to visual impairment and can result in irreparable damage. Unequal pupils, abnormal eye movements, and abnormal pupillary reactions are some of the common symptoms of optic nerve damage.
Symptoms that require immediate attention
There are several symptoms that might indicative of a neuro-ophthalmological problem, like:
- Visual hallucinations
- A sudden decrease in vision
- Sudden loss of vision
- Defects with visual fields
- Strabismus (Cross-eyed/squints)
- Pupillary abnormalities
- Bright light intolerance
- Double vision
- Impairment in colour vision
A neuro-ophthalmologist effectively recognises these symptoms and initiates treatment likewise. While problems related with neuro-ophthalmology may not always be severe, they can be damaging if not treated timely.
Types of diseases pertaining to neuro-ophthalmology
Several eye disorders require the immediate attention of a neuro-ophthalmologist, like:
Nutritional Optic Neuropathy:
It is an eye disorder that relates to inflammation of the optic nerve. The inflammation can happen due to various reasons like an eye infection or some autoimmune disorder.
It is a condition in which the optic nerve swells up due to pressure from inside the skull. The reasons can be tumours, etc.
Certain toxic substances found in alcohol and tobacco can also damage the optic nerve. Lack of nutrients and deficiency of folic acid and vitamin-B complex can also be the reasons.
In this disorder, the optic nerve gets damaged by excessive blood sugar and diabetes levels. With the disease's progression, the blood supply to the retina gets cut off, leading to loss of vision.
Squints is an eye disorder in which both the eyes cannot align themselves in one direction. Paralytic strabismus happens when the ocular muscles are unable to move the eyes.
Preparing for neuro-ophthalmology evaluation
- Before you head for an appointment, request your treating physician to send reports of your CT and MRI scans in advance to the expert neuro-ophthalmologist.
- You can also mail the reports of your CT and MRI scan before your reach to the neuro-ophthalmologist so that he/she Jun have their reading and analysis.
- Women are generally advised not to wear eye makeup as the physician will take a good look at your eyelids for a proper examination.
- Get a list of all the medications you take so that your neuro-ophthalmologist can have a better insight into your case.
What happens during the evaluation?
- Evaluation for a neuro-ophthalmologic can be one of the most comprehensive eye examinations. This might need a few hours to get completed.
- The doctor will check for your visual acuity test, a complete neurologic exam to check strength, coordination, and sensation.
- Your neuro-ophthalmologist will enquire about your medical history, previous surgeries, hospitalisations, etc.
- You might need to go for tests like an assessment of ocular movement, diplopia charting, and evaluation of contrast sensitivity and colour vision, etc.
- The neuro-ophthalmologist will review all your tests and observations, then will discuss the best possible diagnosis. He/she might ask you for additional testing if it is needed.
