Pattern one
The post-concussion patient at month three
Symptoms unchanged after the expected recovery window, every test normal, and increasing frustration. Functional testing usually finds something specific and nameable.

When the Scan Is Clear and the Symptoms Are Not
The most common thing patients tell us after a head injury is that every test came back normal and the symptoms continued. That is not a contradiction. Imaging shows structure, an eye examination shows ocular health, and neither measures how the brain is using vision. That third thing is what a neuro-optometric assessment covers.

What Is Actually Being Tested
Three Examinations, Three Different Questions
Understanding what each investigation is designed to answer explains why a person can pass all of them and still be genuinely unwell.
Imaging asks whether there is structural damage. It is very good at that and largely silent on function. An eye examination asks whether the eye is healthy and whether the refraction is correct — again, both important, and both compatible with severe functional impairment. Neither is designed to detect a coordination problem.
A neuro-optometric assessment asks a third question: how accurately and how sustainably is the visual system doing its job. Eye movements that overshoot a target by a small margin, a convergence system that holds for ten seconds and then gives way, a mismatch between what the eyes report and what the balance system expects — these are measurable, they explain the symptoms well, and they are invisible to the other two examinations.
Why the Symptoms Sound Vague
Post-concussive visual complaints are described in unhelpful language — feeling off, not right in busy places, tired eyes, difficulty reading — because the underlying deficits have no everyday vocabulary. Measured properly they become specific: saccadic accuracy, vergence facility, visual motion tolerance. Naming them is often the first useful thing that happens.
When to Seek an Assessment
Symptoms That Warrant Neuro-Optometric Testing
Persisting beyond about four weeks after a head injury, or present at any point after a stroke.
01
Reading that has become effortful or impossible since the injury, with words moving, doubling or refusing to stay still.
02
Dizziness, nausea or a feeling of disorientation in supermarkets, busy streets or anywhere with a lot of visual movement.
03
Light sensitivity that has not settled, particularly under fluorescent or strongly patterned lighting.
04
Difficulty with screens that is out of all proportion to the time spent on them, with symptoms building within minutes.
05
A sense that vision is not quite right that nobody has been able to explain, despite normal imaging and a normal eye test.
New or worsening neurological symptoms need urgent medical assessment, not an optometric appointment. We will say so and redirect you.
Our Programme
How a Neuro-Optometric Assessment Runs at the Chennai Clinic
A ninety-minute in-clinic assessment, with written findings sent to your neurologist or treating team.
01
Baseline binocular assessment
An extended clinic appointment: symptom history anchored to the injury date, then alignment, vergence ranges, accommodative accuracy, fixation stability, eye movement accuracy and field screening, with fatigue deliberately built into the testing rather than avoided.
02
Getting the correction right first
Optical correction reviewed against the neurological picture, including any prism indicated for a measured deviation, with adaptation allowed before functional work begins.
03
Active therapy sessions
Graded rehabilitative work in clinic with short daily practice, sequenced so that stability precedes speed and speed precedes visually complex environments.
04
Reassessment, then taper
Review against the intake profile, with the treating team copied in, and an explicit statement of what has changed and what is unlikely to change further.

Who Reaches Neuro-Optometry in Chennai
Chennai has strong neurology and rehabilitation services, and the visual component of recovery is frequently the piece that nobody has been asked to look at.
Pattern two
The stroke survivor with a reading problem
Physiotherapy and speech therapy in place, reading difficulty unaddressed because it was assumed to be language rather than visual scanning.
Pattern three
The balance patient with a visual driver
Under vestibular physiotherapy with partial progress. The visual-vestibular mismatch is often the part that has not been assessed.
In clinic, and between visits
In-clinic at our Chennai practice, with a second location in Anna Nagar East for families in the north of the city. A neuro-optometric assessment is largely history, symptom mapping and functional testing, all of which hold up on video without compromise.
Typical schedule
A longer first appointment than most, then fortnightly rather than weekly, because neurological recovery does not respond well to being hurried. Sessions are timed around school hours and the coaching-class evening.
Records that change the assessment
The discharge summary, any imaging report, and the date of injury. These change what gets tested and in what order. Anything that must happen in person is arranged at the clinic during a scheduled visit.

Common Questions
Neuro-Optometry in Chennai — Common Questions
My neurologist says everything is fine. Is it worth a second kind of assessment?
Your neurologist is answering a different question, and answering it correctly. They are excluding structural and medical causes, which is the right first priority and reassuring when it comes back clear. What that examination does not cover is functional visual performance — whether your eye movements are accurate, whether convergence sustains, whether visual and vestibular input agree. Those are measurable, they explain post-concussive symptoms well, and finding them does not contradict anything your neurologist said.
Is this available in-clinic in Chennai?
Yes. Chennai is one of our two physical clinics and neuro-optometric assessment is a case where in-person matters more than most: testing visual function under head movement, assessing balance-related symptoms and screening the visual field are all better done in a room. Later therapy sessions can move to video where travel is difficult, but the baseline assessment should be face to face and we would recommend it that way.
It has been two years since my accident. Is there any point now?
Probably, though with a lower ceiling than at three months. Oculomotor control, vergence and visual scanning all remain trainable years after an injury, and people who have been symptomatic for a long time often make useful gains simply because nothing has ever been targeted at the actual deficit. What changes with time is the rate and the realistic endpoint. We would measure first and give you a specific prognosis, including telling you if the likely gain does not justify the programme.
What is a neuro-optometrist?
An optometrist with additional training in the visual consequences of neurological injury and disease. The scope is functional rather than surgical or pharmacological: how the visual system aims, focuses, stabilises and integrates after a brain injury, stroke or neurological condition, and what can be rehabilitated. It is not a separate primary qualification in most countries but a defined area of post-qualification training and practice, which is why asking about the specific training is reasonable.
How is this different from seeing a neurologist or an ophthalmologist?
They answer different questions and you may well need more than one. A neurologist investigates the neurological condition itself. An ophthalmologist examines the structural health of the eye and treats disease within it. A neuro-optometrist assesses how well the visual system functions after those questions have been addressed, and what functional rehabilitation is available. None of the three substitutes for the others, and we work alongside rather than instead of them.
