Binocular Vision Clinic at Sankara Nethralaya (Main Campus) takes a giant step towards providing vision care to the neurologically challenged.

The Binocular Vision Clinic, Sankara Nethralaya (Main Campus) as part of its ongoing measures towards providing specialized eye care to people with specific vision problems has started the “Neuro-Optometric Clinic’ a strategic eye care initiative which would address the visual needs and provide relief to those suffering from ocular disturbances caused due to traumatic brain injury (TBI), Cerebro-vascular insults, multiple sclerosis, brain tumors and other neurological illnesses. The clinic focuses to advance the art and science of visual rehabilitation of the neurologically challenged population.

Patients with Traumatic Brain Injury/stroke can exhibit a wide variety of symptoms as given below and could benefit from the treatment offered at the specialized “Neuro-Optometric Clinic’

o Diplopia, squinting of eyes, restriction of eye movements
o Headaches
o Difficulty to focus from distance to near or vice-versa
o Dizziness/ nausea, vertigo , light sensitivity, motion sensitivity and balance disorders
o Difficulty in cognitive ability, difficulty in concentration, visual neglect and visual processing
o Right-left discrimination
o Difficulty in object recognition (Agnosia)
o Difficulty in manipulation of objects (Apraxia)
o Memory loss
o Psychological problems
o Visual hallucinations
o Convergence and accommodative deficit
o Visual field defects
o Visual midline shift
o Dry eyes

Advanced Tests done at the Neuro- Optometry Clinic include

1. Detailed history ( Details of brain injury, Loss of consciousness following trauma, ENT bleeding, Type of Surgery done, Imaging reports, therapy provided, specific ocular and non-ocular symptoms)
2. Refraction
3. Sensory Motor evaluation
4. Vestibulo-ocular reflexes, Pursuits and Saccadic evaluations
5. Comprehensive Binocular Vision Assessment (Manual/ Computerized)
6. Tests of Visual Perceptual Skills
7. Assessment of reading speed
8. Color Vision, Pupillary evaluation, Confrontation/Visual field assessment , Amsler charting and Cranial Nerves evaluation
9. Diplopia and Hess charting (for diplopia)
10.Prism trial for strabismus/ nerve palsy, visual field defects like hemianopia and Balance disorders

Vision rehabilitation at the NOC

The clinic utilizes therapeutic prisms, lenses, filters and occlusion to help these patients improve the function of their vision potential which is affected due to the brain injury. In addition to the rehabilitation, vision therapy may be provided to those with binocular vision anomalies to enhance the accommodation and vergence functions and to train visual processing skills.

The sequencing of treatment at the NOC:

1. Glasses for refractive errors for distance and near
2. Prism therapy for diplopia/ field expanders
3. Colored filters and tints for photosensitivity
4. Binasal occluders to train for abduction restrictions
5. Vision therapy for the accommodative and vergence dysfunctions
6. Perceptual therapy for visual processing disorders
7. Eye movement/ tracking exercises
8. Vestibulo-ocular and balance disorders training
9. Assistive technology to enhance reading
