Balance Problems After a Concussion: When the Eyes and Inner Ear Are Involved

Many people leave the emergency room after a concussion with good news: the CT scan is clear. Days later, the grocery store feels like the deck of a boat. Turning your head quickly makes the world lag a half second behind. Rolling over in bed sends the ceiling spinning.  

That gap between a normal scan and a body that feels anything but normal is one of the most confusing parts of concussion recovery. Very often, the explanation lives in two places imaging doesn't really evaluate: the eyes and the inner ear. These problems can usually be measured, and many respond well to targeted treatment.  

How Your Brain Keeps You Upright

Three Systems Working as One Team

Steady balance depends on three main inputs:  

• Vision, which tells your brain where you are relative to the world around you  
• The vestibular system, a set of tiny sensors in the inner ear that detect head motion and gravity  
• Proprioception, the position sense coming from your muscles, joints, and feet  

Why a Concussion Can Throw Off the Signals

A concussion can disrupt this system in two ways. The force of the injury may affect the sensors themselves, such as the inner ear. It may also affect the brain's ability to process and combine their signals. Educational resources from the CDC HEADS UP program illustrate how mild traumatic brain injuries often disrupt complex neural pathways without causing visible structural damage.  

Either problem can lead to dizziness, a foggy or "floating" feeling, motion sensitivity, or unsteadiness that comes and goes.  

Why a Clear Scan Doesn't Rule This Out

CT scans and MRIs look for structural injuries like bleeding or swelling. They don't measure how your eyes track or how your inner ear responds to movement. A clear scan is reassuring, but it doesn't confirm your balance systems are working well. That's where objective concussion testing comes in.  

When the Inner Ear Is Part of the Problem

BPPV: The Dizziness That Strikes When You Roll Over

Benign paroxysmal positional vertigo (BPPV) is one of the more common inner ear problems after head trauma. It happens when tiny calcium crystals in the inner ear shift out of place.  

The biggest clue is timing. BPPV usually causes short, intense spinning spells triggered by specific positions, such as:  

• Lying down or getting out of bed  
• Rolling over at night  
• Looking up at a high shelf  

Vestibular Hypofunction and the Vestibulo-Ocular Reflex

Your vestibulo-ocular reflex (VOR) keeps your vision steady while your head moves. When the inner ear isn't sending strong enough signals, that reflex weakens.  

People often describe the world blurring or "bouncing" when they walk, turn their head, or check mirrors while driving. Reading signs while moving can feel nearly impossible.  

Less Common Inner Ear Injuries

Head trauma can occasionally cause labyrinthine concussion or a perilymph fistula. New hearing loss, ringing in the ear, or a sense of fullness after an injury should be evaluated promptly.  

When the Eyes Are Part of the Problem

Convergence Insufficiency

Convergence is your eyes' ability to turn inward together to focus on something close. When it's impaired, near tasks become tiring. Common signs include:  

• Double or blurred vision while reading  
• Eye strain or headaches during phone or computer use  
• Rereading the same line over and over  
• Closing one eye to focus  

Tracking and Eye Jump Problems

Smooth pursuits follow a moving object, like a passing car. Saccades are quick jumps, like moving from word to word on a page.  

After a concussion, these movements can become slow or inaccurate. People may lose their place while reading, struggle with screen work, or feel worn out after short visual tasks.  

Visual Motion Sensitivity

Some people become highly sensitive to busy visual environments. Big box stores, traffic, scrolling, and crowds can trigger dizziness or nausea.  

The brain may lean too heavily on vision and get overwhelmed. Many people start avoiding these places, which quietly shrinks daily life.  

Eyes or Inner Ear? Sorting Out the Clues

Symptom Pattern

How Specialists Test the Eyes and Inner Ear

Vestibular/Ocular Motor Screening (VOMS)

VOMS is a widely used concussion screening tool. Research documented on PubMed / NCBI demonstrates that targeted vestibular and oculomotor screenings reliably identify functional deficits that correlate with extended recovery times. It tracks whether eye and head movement tasks increase symptoms like headache, dizziness, or nausea, and measures near point of convergence.  

Positional Testing for BPPV

During tests like the Dix-Hallpike maneuver, a clinician moves the head into specific positions and watches the eyes. Certain eye movements can confirm BPPV and show which canal is affected.  

Eye Tracking and Balance Measurements

More detailed assessments may record eye movements during tracking and gaze tasks. Balance testing can also show how well a person stays steady when visual or surface information changes.  

Why Measurable Findings Matter

"I still feel off" is real, but it's hard to track. A recorded baseline helps patients, clinicians, and care teams see whether treatment is working and adjust the plan when it isn't. Grounded in our clinical mission & vision, our goal is to bring clarity and objective documentation to every stage of patient care.  

Treatment and Recovery: What Rehab Can Do

Repositioning Maneuvers for BPPV

BPPV is often treated with guided head and body movements, such as the Epley maneuver. These guide displaced crystals back into place, and many people notice improvement within a few sessions.  

Vestibular Rehabilitation Therapy

Vestibular rehabilitation uses specific exercises to retrain the brain. It may include:  

• Gaze stabilization to keep vision steady during head movement  
• Habituation to gradually reduce sensitivity to triggering movements or environments  
• Balance training to rebuild confidence on uneven surfaces and in busy spaces  

Vision-Based Exercises

When the eyes are involved, therapy may target convergence, tracking, and quick eye jumps. This can make reading and screens more comfortable.  

Setting Realistic Expectations

Some people improve within weeks, while others need longer, especially when several systems are involved. Doing too much too soon can flare symptoms, but avoiding all movement may slow progress too. A guided plan helps find that middle ground, which also matters for anyone dealing with persistent post-concussion symptoms.

Common Questions About Dizziness After a Concussion

Can a concussion cause vertigo weeks after the injury?

Yes. Some people first notice vertigo days or weeks later, often once they return to normal activity. BPPV can also show up after the early symptoms settle.  

How long do balance problems last after a concussion?

It varies. Many people improve within weeks, while others have symptoms for months.  

Will vestibular problems show up on an MRI?

Usually not. These problems are functional, so specialized testing identifies them rather than imaging.  

Is it safe to drive with post-concussion dizziness?

Driving depends on stable vision and quick head turns. If you feel dizzy or foggy or have blurred vision, talk with your provider before getting behind the wheel.  

How do I get vestibular or oculomotor testing?

A good first step is a phone call with our team to talk through your symptoms. We can explain how evaluation works and what next steps fit your situation.  

Steadier Footing Begins With Finding the Source

Feeling unsteady after a head injury can make ordinary places seem unpredictable. A trip to the store, a drive across town, or a shift at work starts to feel like something to brace for. That kind of uncertainty wears on people, and on the families who watch them struggle.  

Dizziness tied to the eyes or inner ear isn't a vague side effect you simply have to wait out. These are specific systems that can be tested, measured, and often treated. For patients and referral partners alike, pinpointing the source is what makes a focused plan possible.
