Cortical visual impairment (often called cerebral visual impairment) is a vision problem caused by how the brain processes visual information, not by a problem with the eyes themselves. In CVI, the eyes can be healthy or only mildly affected, but the parts of the brain that see, recognize, and understand what the eyes send are not working normally. This is why a child (or adult) with CVI may look at something but not make sense of it, or may see well in one situation and poorly in another. CVI is now recognized as a leading cause of childhood visual impairment in many countries. People can have CVI from birth or develop it later after illness or injury.

Think of vision like a camera connected to a computer. The eyes are the camera. The optic nerves and visual pathways are the cables. The visual cortex and visual networks in the brain are the computer. In eye diseases, the camera is damaged. In CVI, the camera can be fine, but the computer or cables are not processing pictures correctly.

Vision is more than seeing sharp letters on a chart. It also includes recognizing faces, finding a toy in a messy room, judging steps and curbs, copying shapes, following moving objects, and understanding what we see. These skills depend on many brain areas working together: the occipital lobes (basic seeing), the dorsal stream (“where/how” pathway that guides movement and spatial awareness), and the ventral stream (“what” pathway that helps recognize objects and faces). In CVI, some of these networks are damaged, under-developed, or working slowly, so visual behavior becomes unreliable. Children with CVI may improve over time because the brain can adapt, but progress varies.

A key sign of CVI is variability: the same child may see something one day but not another. Busy environments, clutter, noise, illness, tiredness, or low contrast can make vision much worse. Simpler, high-contrast, single-color, slow-moving objects in a quiet space may be easier.

Types of CVI

There is no single “official” list of types used everywhere, but clinicians often describe CVI using several helpful categories. These types can overlap in the same person.

1. By timing

   • Congenital (from birth): vision processing problems start early due to pregnancy, birth, or newborn events (for example, prematurity or lack of oxygen).

   • Acquired (after early life): vision processing problems appear later due to head injury, stroke, infection, or other brain illness.

2. By brain pathway involved

   • Dorsal stream (the “where/how” pathway) CVI: trouble with movement, depth, spatial awareness, visually guided reach, and finding things in clutter. Stairs, curbs, or busy rooms are hard.

   • Ventral stream (the “what” pathway) CVI: trouble recognizing faces, shapes, letters, and objects, especially when they are new, small, or look similar.

3. By severity

   • Mild: can use vision well in simple settings; problems show up in clutter, low contrast, or fast tasks.

   • Moderate: needs clear supports (single objects, strong contrast, fewer distractions); inconsistent performance is common.

   • Severe: limited reliable vision; may rely more on touch, hearing, or routine; still may prefer certain colors or movement.

4. By pattern of visual field loss

   • Some children (especially with periventricular white-matter injury) have lower visual field loss and may trip over ground-level objects. Others may have left or right field loss or scattered blind spots.

5. By stability

   • Improving (common in early years as the brain adapts), stable, or fluctuating (worse with fatigue, illness, or stress).

6. By associated brain condition

   • Linked to prematurity/PVL, hypoxic-ischemic injury, stroke, traumatic brain injury, epileptic encephalopathy, hydrocephalus, genetic/metabolic conditions, or infections.

These labels help plan support: simplify visuals (ventral problems), reduce clutter and add motion markers (dorsal problems), add tactile cues for field loss, or pace tasks for slow processing speed.

Causes of CVI

CVI has many causes. Below are 20 common or important causes, each explained simply. Many children have more than one cause.

1. Lack of oxygen or blood to the brain around birth (hypoxic-ischemic encephalopathy, HIE).
   When a baby’s brain does not get enough oxygen or blood during labor, delivery, or soon after, visual brain areas can be injured. This can lead to long-term problems with how pictures are processed.

2. Prematurity with white-matter injury (periventricular leukomalacia, PVL).
   Babies born very early have fragile brain white matter (the “wiring” that carries signals). Damage near the brain’s ventricles often affects the optic radiations and pathways needed for normal vision, especially the lower visual field.

3. Bleeding in or around the brain (intraventricular or intracranial hemorrhage).
   Bleeding in premature or sick newborns can harm nearby visual pathways, leaving lasting processing difficulties.

4. Stroke in infancy or childhood (ischemic or hemorrhagic).
   A blocked or burst blood vessel can damage the occipital lobes or the pathways that carry vision signals, causing field loss, recognition problems, or both.

5. Traumatic brain injury (including abusive head trauma).
   Falls, car crashes, sports injuries, or shaking can injure the brain’s visual areas and connections. Problems may become more obvious when school tasks grow complex.

6. Brain infections (meningitis or encephalitis).
   Infection and swelling can harm brain tissue that handles vision, leading to variable and sometimes severe CVI.

7. Infections before birth (congenital infections such as CMV, toxoplasmosis, rubella, syphilis, herpes, or Zika).
   These can disturb brain development, including areas important for seeing and recognizing.

8. Hydrocephalus and pressure effects.
   If fluid builds up in the brain (hydrocephalus), nearby white matter and visual pathways can be stretched or damaged; shunt problems can add new injury.

9. Frequent or severe seizures (epileptic encephalopathy).
   Repeated seizures or abnormal background brain activity may disrupt visual networks, causing slow processing and recognition issues.

10. Metabolic disorders (for example, mitochondrial or peroxisomal disease).
    When brain cells cannot produce energy normally, high-demand systems like vision networks are vulnerable, leading to CVI features.

11. Genetic brain malformations (e.g., lissencephaly, polymicrogyria, cortical dysplasia).
    If the brain’s cortex or connections form abnormally, visual processing can be reduced or inconsistent, even with healthy eyes.

12. Low blood sugar injury in newborns (neonatal hypoglycemia).
    Very low sugar can hurt sensitive brain areas, including the occipital lobes, and later cause vision processing problems.

13. Severe newborn jaundice with brain injury (kernicterus).
    Very high bilirubin can injure parts of the brain and leave vision processing difficulties together with movement or hearing issues.

14. Brain tumors along the visual pathway or occipital cortex.
    Tumors or treatments (surgery, radiation) can affect how visual signals travel or are processed.

15. Inflammatory demyelinating disorders (e.g., ADEM, multiple sclerosis).
    Inflammation that strips myelin (the insulation on nerve fibers) can slow or block visual signals within the brain.

16. Brain injury around heart surgery, ECMO, or severe illness.
    Children needing complex heart care or life support can have small injuries to brain white matter, sometimes leading to CVI-like difficulties.

17. Cardiac arrest or severe low blood pressure later in life.
    Any event that starves the brain of oxygen can damage visual processing areas and create CVI symptoms.

18. Prenatal alcohol or drug exposure (fetal alcohol spectrum and related effects).
    Alcohol and some drugs can alter brain development, including networks for attention, recognition, and spatial vision.

19. Leukodystrophies and other neurodegenerative diseases.
    Progressive white-matter disorders can slowly degrade visual pathways, causing worsening CVI features over time.

20. Autoimmune encephalitis or other immune-mediated brain injury.
    The immune system can attack brain tissue, including visual networks, leading to new problems with recognition, field awareness, or processing speed.

Common symptoms and behaviors in CVI

Children and adults with CVI do not all look the same. These 15 features are often reported. The same person may show only some of them, and strength can change day to day.

1. Inconsistent vision from day to day.
   The person may see a toy on Monday but ignore it on Tuesday. Illness, noise, clutter, and fatigue can make vision worse.

2. Slow visual response time.
   It may take several seconds to look at, notice, or reach for an object. If you wait quietly, vision often “comes in.”

3. Better with movement.
   Slowly moving or gently shaking an object can “wake up” vision. Spinning pinwheels or moving light dots may be easier to see.

4. Strong color preferences.
   Bright, saturated colors (often red or yellow) may be easier than pastels or mixed colors. A single bold color can make an object “pop.”

5. Attracted to light or bothered by it.
   Some stare at windows or lights; others are light sensitive and turn away. Both patterns are common.

6. Trouble in cluttered scenes (crowding).
   Finding a spoon in a drawer or a toy on a busy shelf is hard. Single items on a plain background are easier.

7. Visual field differences.
   The person may miss objects low on the ground (lower field loss), or on one side, or near midline. This can cause tripping or bumping.

8. Better peripheral than central vision.
   They may notice things “out of the corner of the eye” but lose them when they try to look straight on.

9. Trouble recognizing faces (face blindness-like).
   They may know someone by voice, hair, or glasses rather than by face details, especially in a crowd.

10. Trouble recognizing objects, symbols, and letters.
    New or similar-looking objects are confusing. Simple, familiar items in strong contrast are best.

11. Poor depth judgment and step/curb problems.
    Stairs, playground equipment, and changes in floor color can be scary or lead to missteps.

12. Reaching errors (optic ataxia).
    The hand may reach above, below, or beside the target, especially in clutter or when eyes and hand must work together quickly.

13. Navigation and movement difficulties (dorsal stream issues).
    Walking through a busy hallway or crossing a street may feel overwhelming because the scene is moving and complex.

14. Visual fatigue.
    Using vision is hard work. After short periods, the person may look away, rub eyes, or prefer to listen or touch instead.

15. Atypical eye contact or social gaze.
    They may seem to “avoid eye contact,” not because of rudeness or lack of interest, but because face processing is hard or slow.

Diagnostic tests for CVI

Doctors do not diagnose CVI with a single machine or a single number. Instead, they combine a detailed history, observation of visual behavior, eye examinations, brain tests, and sometimes lab studies to look for causes. Below are 20 tests, grouped by Physical Exam, Manual tests, Lab & Pathological, Electrodiagnostic, and Imaging. Each test is described simply and includes why it helps.

Physical exam

1. General neurological examination.
   The doctor checks muscle tone, reflexes, balance, coordination, and how the person moves and uses both sides of the body. This helps link visual behaviors to brain patterns and spots other issues (for example, cerebral palsy) that often travel with CVI.

2. Developmental and functional assessment.
   Simple tasks are used to see how the person plays, reaches, communicates, and learns. Vision in CVI is tied to attention, motor skills, and sensory processing, so this broader picture matters.

3. Observation of visual behavior in natural settings.
   Watching how the person looks, reaches, and navigates at home or school shows real-world strengths and struggles. Doctors look for variability, color preference, clutter effects, field differences, and slow visual response.

4. External head and eye exam (alignment, pupils, movements).
   Although CVI is a brain-based condition, basic eye checks are still needed. The doctor looks for strabismus (eye turning), nystagmus (shaking), or pupil problems that might add to the visual difficulty.

Manual (bedside/clinic) tests

5. Fixation and following.
   A high-contrast target (like a black-and-white card or bright toy) is moved slowly while the examiner watches if the person can fix on it and smoothly follow it. In CVI, fixation may be brief, delayed, or better when the object moves or is a favored color.

6. Blink-to-threat / menace response.
   A quick hand motion toward the eyes (without touching lashes) or a small object approaching tests automatic protective blinking. In some CVI cases, this response is reduced or inconsistent even when the eye itself is healthy.

7. Confrontation visual fields (child-friendly).
   While the person looks at the examiner’s nose, a toy or finger wiggles in different areas to map what parts of the field are noticed. Children with PVL-related CVI may miss lower-field objects, explaining tripping.

8. Optokinetic nystagmus (OKN) drum or strip.
   Stripes moving across the visual field normally produce a reflex eye movement. Presence of OKN suggests basic visual pathways work, even if recognition is poor. Absent or weak OKN can point to broader pathway problems.

9. Preferential looking visual acuity (Teller, Cardiff, Lea paddles).
   Instead of reading letters, infants or non-verbal people are shown cards with fine stripes or simple pictures to see if their gaze chooses the patterned side. This estimates acuity when a standard chart is not possible and reveals if acuity is better than behavior suggests.

10. Contrast sensitivity and crowding checks (e.g., Hiding Heidi or crowded symbols).
    Low-contrast faces or crowded letters can be very hard in CVI. Simple tools show how much contrast or how much spacing is needed. This guides classroom materials (bold print, more spacing).

Lab & pathological tests

11. Metabolic screening (blood/urine for energy disorders).
    Tests like lactate, pyruvate, amino/organic acids, acylcarnitines, and others can hint at mitochondrial or metabolic diseases that damage brain networks.

12. Infection evaluation (as needed).
    Depending on history, tests can look for congenital infections (e.g., CMV, toxoplasma) or past meningitis/encephalitis that might explain the timing of brain injury.

13. Genetic testing (chromosomal microarray and/or exome sequencing).
    If brain structure differences or development concerns exist, looking for a genetic cause can explain the wider picture and guide counseling and supports.

14. Stroke, endocrine, or clotting work-ups (when indicated).
    If a stroke or unstable blood sugar is suspected, labs for clotting tendencies, heart evaluation, or glucose/hormone checks help pinpoint and prevent further injury.

Electrodiagnostic tests

15. Visual evoked potentials (VEP).
    Small electrodes on the scalp measure the brain’s electrical response to a flashing pattern. In CVI, VEP may be delayed or abnormal, showing slow or weak signal processing in the visual cortex even when the retina is normal.

16. Electroretinography (ERG).
    ERG measures how the retina responds to light. A normal ERG with abnormal VEP supports a brain-based cause (CVI) rather than an eye disease. This helps separate CVI from retinal conditions.

17. Electroencephalogram (EEG).
    EEG looks for seizures and background brain patterns that can disrupt vision. Treating uncontrolled seizures can improve attention and visual use in daily life.

Imaging tests

18. Brain MRI (preferably with attention to visual pathways; DTI when available).
    MRI can show injury in occipital lobes, optic radiations, or periventricular white matter (PVL). Diffusion tensor imaging (DTI) maps white-matter tracts and may show pathway disruption. MRI guides prognosis and therapy planning.

19. Cranial ultrasound (in newborns).
    For premature infants, ultrasound at the bedside can detect bleeding (IVH) or white-matter injury early, long before MRI is practical, and prompt early supports that also consider vision.

20. CT scan (for acute situations or when MRI is not possible).
    CT rapidly shows bleeding or major strokes after an accident or sudden symptoms. It is less detailed for white matter than MRI but still vital in emergencies.
    Note: Eye imaging like OCT (optical coherence tomography) may be used in some cases to check the retinal nerve fiber and ganglion layers. In CVI, OCT can be normal or show thinning from “backward” (retrograde) effects of brain injury; findings are used together with all the other tests.

Non-pharmacological treatments

Core truth: There is no cure yet, but early, individualized, education-centered intervention works best. Goals are to (1) remove barriers that overwhelm the child’s visual brain and (2) teach skills with smart, step-by-step supports. AAP PublicationsNational Eye Institute

1. Simplify the scene: Present one object on a plain background. Purpose: reduce visual “crowding.” Mechanism: lowers processing load on dorsal/ventral streams.

2. Increase contrast: Dark-on-light or light-on-dark. Purpose: make targets “pop.” Mechanism: stronger signal-to-noise for the brain.

3. Use preferred color accents (often red/yellow): Purpose: faster detection. Mechanism: leverages color pathways that may be relatively resilient.

4. Use movement wisely: Slowly move or gently shimmer a target. Purpose: grab attention. Mechanism: taps motion-sensitive networks that can cue fixation.

5. Allow extra viewing time: Count “one-Mississippi…five.” Purpose: lets visual latency resolve. Mechanism: gives processing time.

6. Reduce auditory/tactile distraction during visual tasks: Purpose: prevent overload. Mechanism: less cross-modal competition.

7. Positioning and posture support: Stable trunk/head with seating, standers, or pillows. Purpose: free the brain to focus on seeing. Mechanism: lowers motor effort and sensory noise.

8. Visual fields practice: Present items where the child does see best, then gradually expand. Purpose: safe navigation. Mechanism: compensatory scanning routines.

9. Stepwise complexity: Start simple (single color block), then add details gradually. Purpose: build tolerance. Mechanism: progressive neural efficiency.

10. Familiar-to-novel sequencing: Teach with known items before new ones. Purpose: anchor recognition. Mechanism: engages memory networks to scaffold perception.

11. Backlighting / task lighting: Light boxes, screens, or under-lighting. Purpose: increase salience. Mechanism: amplifies luminance cues.

12. Larger size / increased spacing: Bigger targets and generous spacing between items/letters. Purpose: reduce crowding. Mechanism: lower cortical interference.

13. Consistent markers for people/places (e.g., bright scarf): Purpose: faster recognition. Mechanism: creates reliable visual hook.

14. Multisensory teaching (pair touch/voice with vision): Purpose: support understanding. Mechanism: cross-modal integration.

15. Routine and predictability: Same setup, same order. Purpose: reduce novelty load. Mechanism: frees processing for the target.

16. Orientation & Mobility (O&M) training: Safe movement indoors/outdoors. Purpose: independence. Mechanism: structured scanning, landmarking, route planning.

17. Low-vision rehabilitation & assistive tech: Magnifiers, screen readers, high-contrast themes, captioning. Purpose: access to learning. Mechanism: optimizes remaining vision and alternatives.

18. Glasses / refractive correction if needed: Treat the eye part too. Purpose: remove avoidable blur. Mechanism: clearer input to the brain.

19. CVI-informed educational plans (IFSP/IEP): Written accommodations (lighting, clutter control, extra time, font/spacing, testing supports). Purpose: sustained access at school.

20. Caregiver and teacher training: Everyone uses the same strategies, every day. Purpose: consistency. Mechanism: high-repetition learning.

Medicines: what helps—and what does not

Bottom line first: There is no medication proven to directly cure or reverse CVI. Care is centered on education, rehab, and environment design. Medicines are used to manage associated conditions (like seizures, spasticity, sleep problems, reflux, attention challenges) that can make visual functioning worse if uncontrolled. National Eye InstituteHealthyChildren.org

Below are 10 medication categories commonly used for co-occurring issues in children with CVI. These are not CVI cures. Doses must be individualized by the child’s clinician.

1. Anti-seizure medicines (e.g., levetiracetam, oxcarbazepine). Purpose: control seizures that disrupt vision/learning. Mechanism: stabilizes neuronal firing.

2. Spasticity medications (e.g., baclofen, tizanidine; botulinum toxin injections as procedures). Purpose: better posture/comfort → better visual engagement. Mechanism: reduces hypertonia.

3. Sleep supports (e.g., melatonin under medical guidance). Purpose: reduce fatigue-related visual fluctuation. Mechanism: circadian regulation.

4. ADHD medications (e.g., methylphenidate) where attention limits hinder visual tasks. Purpose: improve on-task visual learning. Mechanism: catecholamine modulation.

5. GI reflux treatments (e.g., acid suppression when symptomatic). Purpose: comfort → better participation. Mechanism: reduces nociceptive distraction.

6. Constipation management (e.g., osmotic laxatives). Purpose: comfort, behavior regulation.

7. Analgesics for painful comorbidities. Purpose: reduce distraction from pain.

8. Migraine prophylaxis (in children with migraine-related visual strain). Purpose: reduce headache-linked visual avoidance.

9. Tone/ movement disorder targeted meds (e.g., trihexyphenidyl in dystonia). Purpose: steadier gaze posture.

10. Allergy/asthma control when symptoms disrupt sleep/attention. Purpose: protect learning windows.

Again, these do not treat CVI directly; they remove obstacles so the child can make the most of rehab and school supports. The American Academy of Pediatrics/AAO statement emphasizes early identification and individualized, multidisciplinary care, not drug cures. AAP PublicationsAAO

Regenerative, stem-cell drugs

Right now there are no approved immune, regenerative, or stem-cell drugs for CVI. Experimental brain-stimulation and vision-training methods have been studied mainly in adult cortical blindness after stroke, not pediatric CVI, and even there the gains are limited and require long training. Families should avoid clinics promising cures. If you’re exploring research, ask your clinician about registered clinical trials and realistic goals. PMCScienceDirect

Surgeries

Surgery does not cure CVI, but it can help treat co-existing eye or brain conditions that interfere with vision use:

1. Strabismus surgery (for significant esotropia/exotropia): improves eye alignment, which can aid comfort, function, and amblyopia prevention. EyeWiki

2. Cataract surgery (if cataract exists): removes media opacity so the brain receives clearer images.

3. Hydrocephalus shunt/endoscopic third ventriculostomy (when indicated): protects brain tissue from pressure-related injury.

4. Refractive lens procedures are rare in children—glasses/contacts are standard; surgery is only for special indications.

5. Epilepsy surgery (selected severe cases): aims to control seizures that block learning; not a direct treatment for CVI.

---

Prevention ideas

We prevent risk factors, not CVI itself:

1. Excellent prenatal care to reduce prematurity.

2. Safe delivery and skilled newborn resuscitation to reduce low-oxygen injuries.

3. Prevent and promptly treat neonatal hypoglycemia and infections.

4. Vaccination (e.g., meningitis prevention).

5. Helmet and car-seat safety to prevent head injury.

6. Monitor/treat jaundice to avoid kernicterus.

7. Early recognition and treatment of hydrocephalus.

8. Stroke risk management in relevant conditions.

9. Avoid shaken baby syndrome—caregiver support/education.

10. Early developmental screening to catch problems fast and start services.

(These align with pediatric safety and neuro-protection principles referenced in CVI clinical guidance.) AAP Publications

When to see doctors—practical red flags

• A baby who doesn’t make eye contact, doesn’t fix/follow by the expected age, or responds to voices more than faces.

• A child who can find a single toy on a plain mat but is lost in busy rooms.

• Inconsistent vision (worse when tired, hungry, or in noisy places).

• Navigation troubles (curbs, steps, bumping into low objects).

• Any head injury, seizures, or neurologic diagnosis with new visual concerns.

• Teachers noticing visual access problems despite normal eye exams.
  Seek referral to pediatric ophthalmology/low-vision rehab and a CVI-informed educational evaluation. aapos.org

What to eat—and what to avoid (supportive, not curative)

There’s no special CVI diet and no supplement proven to fix CVI. Focus on balanced pediatric nutrition that supports brain development: iron-rich foods; iodine (iodized salt); protein; fruits/vegetables (including leafy greens); healthy fats including natural omega-3 sources (fish where culturally appropriate); adequate hydration; and regular meals to curb fatigue. Limit ultra-processed foods and excess sugar that may worsen attention or energy swings. Always discuss supplements with the child’s clinician, especially for dosing and interactions. National Eye Institute

FAQs

1) Is CVI the same as eye disease?
No. The eyes can be healthy. The problem is in the brain’s visual processing. AAP Publications

2) Can glasses help?
Glasses help with eye focus. They don’t fix CVI, but they remove extra blur that the brain doesn’t need.

3) Will my child’s vision improve?
Many children show improvement over time, especially with early, consistent intervention. The amount varies. EyeWiki

4) Is there a cure or a medicine for CVI?
No cure or proven drug yet. The most helpful “treatments” are educational and rehabilitative strategies plus managing co-occurring issues (seizures, sleep, etc.). National Eye InstituteHealthyChildren.org

5) What does “visual crowding” mean?
Busy scenes overwhelm processing. We beat this by simplifying, using plain backgrounds, bigger spacing, and stepwise complexity.

6) Why does my child “stare at lights” or love certain colors?
Those features stand out more for their brain. We can use that (e.g., color tags) to support learning. aapos.org

7) Are screens bad for CVI?
Backlit screens can help by boosting contrast and size. Keep sessions short, focused, and purposeful.

8) What should teachers change first?
Declutter visual materials, use high contrast and larger print, allow extra time, and teach one new visual demand at a time—all written into the IEP.

9) What assessments are “CVI-informed”?
A CVI-specific evaluation that looks at functional vision in real tasks (home/class), often using tools like the Perkins CVI Protocol to guide accommodations. Perkins School for the Blind

10) Are VEP and MRI always abnormal in CVI?
Not always. CVI is a clinical diagnosis that pulls together history, functional vision, and tests. EyeWiki

11) Can surgery fix CVI?
No. Surgery can help co-existing eye problems (like big esotropia) or hydrocephalus, but it doesn’t “repair” the brain’s visual processing. EyeWiki

12) Is CVI related to autism?
They can co-occur, but they’re different. CVI is about visual processing; autism affects social communication and behaviors. Each needs its own supports.

13) Can CVI be prevented?
We reduce risks by preventing prematurity, infections, and head injury, and by rapid treatment of newborn problems (e.g., hypoglycemia, jaundice).

14) Will my child be able to read?
Many do—with larger print, extra spacing, fewer items per page, and patient, CVI-aware teaching.

15) What matters most right now?
Start early. Keep strategies simple and consistent. Train everyone on the team. Track what works. Small wins add up.
