Concussion Vision Therapy
India
Post-concussion vision problems - double vision, light sensitivity, and convergence failure - affect up to 75% of TBI patients and are routinely missed by standard eye tests. Our NORA-affiliated neuro-optometric rehabilitation programme in Chennai provides structured, evidence-based treatment for adults and children recovering from concussion and TBI.
Why Concussion Disrupts Vision
The visual system runs through the majority of the brain. Concussion disrupts neural systems that coordinate the two eyes, control eye movements, and integrate visual and vestibular information - even when CT or MRI results are normal. Standard acuity tests do not assess vergence, saccades, or vestibulo-visual function, so significant dysfunction is routinely missed.
Research shows up to 75% of TBI patients develop persistent visual symptoms. Convergence insufficiency is present in approximately 50% of cases, alongside oculomotor dysfunction and vestibulo-visual disorders. With structured neuro-optometric rehabilitation, the majority of patients achieve significant functional improvement.

Post-Concussion Vision Symptoms
Key context: These symptoms frequently persist weeks or months after concussion and are often misattributed to anxiety or depression when the actual cause is a measurable visual deficit.
- Double vision (diplopia), horizontal, vertical, or oblique
- Light sensitivity (photophobia) from screens, fluorescent lights, or outdoors
- Convergence failure - text blurs or doubles within seconds of reading
- Balance problems and dizziness in busy or visually complex environments
- Reading difficulty - losing place or poor comprehension despite normal acuity
- Visual-triggered headaches from near tasks, screens, or sustained visual effort
Post-Concussion Vision Rehabilitation - How It Works
Our NORA-affiliated programme is individualised to the specific visual deficits identified at evaluation. No two concussion presentations are identical.
Neuro-Optometric Evaluation
We measure vergence ranges, near point of convergence, accommodative facility, saccadic and pursuit accuracy, VOR function, contrast sensitivity, and photophobia thresholds to identify each patient's specific combination of visual deficits.
Diagnosis & Programme Design
Findings determine which conditions are present - convergence insufficiency, oculomotor deficits, vestibulo-visual dysfunction, or photosensitivity - and a phased plan addresses them in the clinically appropriate sequence.
Supervised In-Clinic Sessions
Weekly 45-60 minute sessions using vergence training equipment, oculomotor tracking tools, VOR and gaze stabilisation activities, and balance integration exercises, progressed as the visual system shows measurable improvement.
Precision Lenses & Prisms
Where photophobia is significant, precision spectral filters reduce cortical hyperexcitability. Therapeutic prism prescriptions address phoria decompensation or diplopia and are adjusted as function changes throughout the programme.
Concussion Vision Therapy FAQs
How long after a concussion should I seek vision therapy?
There is no mandatory waiting period. A neuro-optometric evaluation is appropriate as soon as symptoms stabilise. Patients who reach us months or years after concussion with persistent symptoms also respond well, as neuroplasticity is not limited to the acute phase.
My MRI came back clear. Can I still have post-concussion vision problems?
Yes. Standard neuroimaging detects structural lesions but does not assess functional visual deficits. Post-concussion visual dysfunction arises from disruption to the coordination of visual pathways, not structural damage - a normal MRI is entirely consistent with significant binocular and oculomotor dysfunction on specialist testing.
How is post-concussion vision therapy different from standard vision therapy?
Post-concussion rehabilitation specifically addresses vestibulo-visual integration, gaze stabilisation during head movement, and light sensitivity management beyond standard binocular techniques. Progression must be carefully paced to avoid symptom exacerbation, which is characteristic of post-concussion presentations.
Can vision therapy help with balance problems after concussion?
Yes. Many post-concussion balance problems have a significant vestibulo-visual component. Our programme incorporates gaze stabilisation and vestibulo-visual integration exercises that improve postural stability alongside visual function.
Persistent Vision Problems After a Head Injury?
Our Chennai clinic provides NORA-affiliated neuro-optometric rehabilitation for post-concussion and TBI visual dysfunction.
