Neuro-ophthalmology

Neuro-ophthalmology is a sub-specialty which brings the fields of ophthalmology and neurology together. It deals with the disorders of the optic nerve (a nerve that carries visual information from the eye to the brain), visual pathway and their associations in the brain.

The neuro-ophthalmology team of SCEH is equipped with all tests which are useful in diagnosis and monitoring optic nerve disorders like

  • Visual field examination
  • Color vision and contrast sensitivity testing
  • Optical coherence tomography (OCT) and OCT angiography
  • Electroretinography (ERG)
  • Flash and pattern visual evoked potential (VEP)
  • Fundus Fluorescein angiography (FFA)

SCEH offers treatment as well as rehabilitative services for the disorders of the optic nerve. The disorders are often associated with systemic problems especially brain disorders. Some of the common neuro-ophthalmologic disorders are optic neuritis, ischemic optic neuropathy, optic nerve damage due to compressive lesions in the brain and neural pathways such as brain tumours, nutritional and hereditary optic neuropathies, swelling of the optic nerve, idiopathic intracranial hypertension, cranial neuropathies and optic nerve damage due to trauma, etc. Some forms of squint which result from paralysis of the cranial nerves and lead to double vision, also present to a neuro-ophthalmologist owing to the proximity of these nerves with the optic nerve and visual pathways.

Optic nerve and visual pathways may be affected in several systemic diseases like multiple sclerosis, acute demyelinating encephalomyelitis, toxicity to systemic drugs, several systemic cancers, sarcoidosis and infections like tuberculosis.

The typical symptoms of the optic nerve and visual pathway disorders can be

  • Sudden vision loss in one or both eyes
  • Gradual vision loss in one or both eyes
  • Pain in or around eyes
  • Headache
  • Double vision
  • Color vision disturbances
  • Difficulty in focusing for near

Our team works in close association with neuro-radiologists, neurologists and neuro-surgeons to provide the best possible care for the patients.

SCEH neuro-ophthalmology team offers the following, on a need basis:

  1. Targeted genetic counselling for hereditary optic nerve disorders
  2. Special low vision aids for children and adults
  3. Prism therapy for patients with diplopia due to neurological disorders

A detailed evaluation of the patient involves a thorough clinical evaluation especially of the visual functions, pupils and optic nerve. Apart from the ancillary tests which we provide, based on the nature of disease diagnostic tests like CT scan or MR imaging of the brain, orbits or spinal cord are sometimes necessary. The patients are encouraged to bring their previous records of the systemic illnesses for evaluation at the time of consultation.
