Cortical Visual Impairment Awareness Month: Supporting a Growing Community Wolrdwide

September marks Cortical Visual Impairment Awareness Month, a crucial time to spotlight the leading cause of visual impairment in children across developed countries, including the United States. Cortical Visual Impairment (CVI) is a brain-based visual disorder resulting from damage to the brain’s visual processing centres, not the eyes themselves.

Despite its prevalence, CVI remains underdiagnosed, leaving many children without the necessary support and resources. This article delves into the significance of Cortical Visual Impairment Awareness Month, provides research-backed insights, and highlights available resources to support individuals with CVI and their families.

What Is Cortical Visual Impairment?

Cortical Visual Impairment (CVI), also known as Cerebral Visual Impairment, is a neurological condition where the brain has difficulty processing visual information due to damage or atypical development in the visual pathways. Unlike ocular visual impairments, which stem from issues within the eyes, CVI originates in the brain’s visual processing centres.

Common Causes of CVI:

• Perinatal hypoxia or ischemia (lack of oxygen or blood flow during birth)
  
• Traumatic brain injury
  
• Infections such as meningitis or encephalitis
  
• Hydrocephalus (accumulation of cerebrospinal fluid in the brain)
  
• Stroke affecting the occipital lobe

Recognising CVI: Signs and Symptoms

Children with CVI may exhibit a range of visual behaviours that differ from typical ocular visual impairments. Recognising these signs is crucial for early intervention.

Common Indicators:

• Inconsistent visual responses
  
• A preference for certain colours, especially red or yellow
  
• Difficulty recognising faces or objects
  
• Better visual performance in familiar environments
  
• Delayed visual responses

🔬 The 2025 NIH Breakthrough: 5 Official Elements of CVI That Every Parent Should Know

This is the most important new development in CVI research — and one that every Cortical Visual Impairment Awareness Month article should now include. In May 2025, a team of experts convened by the NIH’s National Eye Institute formally defined CVI for the first time through five key elements. This is a watershed moment for the CVI community.

Experts convened by the National Institutes of Health (NIH) have identified five elements of a brain-based condition that has emerged as a leading cause of vision impairment starting in childhood in the United States and other industrialised nations. (Source: NIH News Release, May 2025)

CVI is a spectrum of visual impairments due to brain abnormalities affecting visual processing pathways, distinct from ocular conditions. Routine vision screenings may miss CVI; clinicians should consider medical history and behavioural characteristics for diagnosis. Emerging technologies like fMRI and DTI show promise in identifying brain abnormalities associated with CVI. (Source: Ophthalmology Times, March 2026)

Here are the NIH’s 5 official elements, explained in plain language:

Element	What It Means for Families
1. Brain involvement	CVI always originates in the brain — not the eyes. The eyes may be perfectly healthy.
2. Unexpected visual dysfunction	Children with CVI show visual difficulties that standard eye tests do NOT detect.
3. Specific visual deficits	Particular difficulties — such as seeing objects against complex backgrounds — that go beyond general low vision.
4. Overlapping disorders	CVI frequently coexists with other neurodevelopmental conditions — autism, cerebral palsy, ADHD.
5. Frequent oversight	CVI is consistently overlooked by clinicians who are not specifically trained to identify it.

(Source: NIH — NIH CVI Workshop Report, Ophthalmology Journal | Ophthalmology Times)

Furthermore, the NIH is now overseeing the development of a CVI Registry to amass data from people with CVI. The database resource will be made available for researchers to study the spectrum of CVI’s signs and symptoms and to define best diagnostic and rehabilitative practices. (Source: NIH)

🏥 The Diagnostic Crisis: Why CVI Gets Missed — and What This Means for Your Child

One of the most painful aspects of CVI — and one of the primary reasons Cortical Visual Impairment Awareness Month exists — is the diagnostic delay. Most children with CVI wait years for a correct diagnosis. And during those years, they are navigating school, therapy, and daily life without the visual support framework they need.

Early detection of CVI is crucial to facilitate early intervention. Studies of children with ocular causes of visual impairment have shown consistent associations between visual impairment and challenges in learning, social relationships, and overall quality of life.

Emerging research on children with brain-based vision impairment shows similar patterns. (Source: Children’s Hospital Los Angeles / Ophthalmology Times, 2026)

Why Is CVI So Often Missed?

Reason	What It Means Practically
Standard eye tests do not detect it	A child can pass a full optometry exam and still have severe CVI
Symptoms overlap with other conditions	CVI looks like autism, ADHD, or developmental delay
Few specialist diagnostic clinics exist	Most paediatricians have received no CVI training
No single diagnostic test	CVI requires clinical expertise, not a scan or blood test
Children with other primary diagnoses are not screened	CVI is rarely looked for in children already diagnosed with CP, autism, or genetic syndromes

Strategies are necessary for early identification of CVI to promote early diagnosis and referral for vision services that may allow a child with CVI to engage more fully in school, activities of daily living, vocational pursuits, and recreational activities. (Source: American Academy of Ophthalmology — CVI Clinical Statement, 2024)

What to Ask Your Doctor During Cortical Visual Impairment Awareness Month

During September, use this awareness month as the prompt to have the conversations your child’s medical team may not have initiated. Ask specifically:

• ✅ “Has my child been assessed for cortical visual impairment specifically — not just a standard eye exam?”
• ✅ “Given my child’s medical history [prematurity / HIE / cerebral palsy / seizures], should we screen for CVI?”
• ✅ “Can you refer us to a specialist who is trained in CVI functional vision assessment?”

🧩 CVI and Special Needs Children: The Connections That Matter Most

Cortical visual impairment does not exist in isolation. It is deeply connected to many of the conditions that bring families to this website.

CVI and Cerebral Palsy

The connection between cerebral palsy and CVI is among the strongest in all of paediatric neurology. Both conditions frequently share the same root cause — brain injury around birth.

Signs of CVI include prematurity, decreased blood supply and oxygenation, brain malformation or infection, hydrocephalus, seizure, metabolic disease, infection, head trauma and other neurologic disorders. (Source: UNC Ophthalmology) Between 26% and 83% of children with cerebral palsy have co-occurring CVI.

CVI and Autism Spectrum Disorder (ASD)

CVI and autism share so many visual and behavioural features that they are frequently confused with each other — or one is missed entirely because the other is present:

Feature	Looks Like Autism	Also a CVI Characteristic
Avoiding eye contact	✅	✅
Staring at lights	✅	✅
Overwhelmed in busy environments	✅	✅
Difficulty recognising faces	✅	✅
Preferring routine and familiar items	✅	✅

For autistic children, any visual processing difficulties beyond what autism alone would explain deserve a CVI-specific assessment. The interventions are different, and getting them right matters enormously.

CVI and Neurodevelopmental Conditions

CVI frequently overlaps with other disorders — including neurodevelopmental conditions. The NIH’s 5 elements of CVI specifically include “overlapping disorders” as one of the key defining features.

This recognition that CVI rarely occurs in isolation is one of the most important advances in understanding the condition. (Source: Ophthalmology Times — NIH CVI Elements)

If your child has any of the following conditions, CVI screening should be considered standard care:

• Premature birth (especially under 32 weeks)
• Hypoxic-ischaemic encephalopathy (HIE)
• Cerebral palsy
• Epilepsy or seizure disorder
• Hydrocephalus
• Traumatic brain injury
• Down syndrome (elevated risk of vision processing differences)
• Meningitis or encephalitis history
• Any genetic syndrome affecting brain development

🔟 The 10 Hallmark Characteristics of CVI: What Research Shows

One of the most important frameworks for understanding CVI comes from the research of Dr. Christine Roman-Lantzy, who identified 10 hallmark characteristics of CVI. These are not just symptoms — they are the distinctive visual behavioural profile that allows a trained specialist to identify CVI.

Knowing these characteristics can help you communicate more precisely with your child’s medical and educational team — and can help you recognise patterns you may have been seeing for years without understanding:

#	CVI Characteristic	What It Looks Like in Daily Life
1	Colour preference	Child reliably responds to red or yellow objects; other colours are harder to see
2	Need for movement	Moving objects are easier to detect than stationary ones
3	Visual latency	Delayed response when looking at things; takes longer than expected to look
4	Visual field preference	Consistently looking to one side; peripheral vision may be stronger
5	Difficulty with visual complexity	Overwhelmed by cluttered rooms, patterned backgrounds, or busy scenes
6	Light gazing	Stares at windows, lamps, or screens rather than people or objects
7	Difficulty with distance viewing	Much easier to see things when close; poor distance vision
8	Atypical visual reflexes	Does not blink or react when an object moves quickly toward the face
9	Difficulty with visual novelty	Familiar objects are far easier to see than new ones
10	Absent or atypical visually guided reach	Reaches inaccurately for objects based on sight

(Source: Perkins School for the Blind — CVI by the Numbers | Pediatric CVI Society)

Furthermore, these 10 characteristics exist on a spectrum. The CVI Range — developed by Dr. Roman-Lantzy — allows clinicians and educators to assess severity from Phase I (most severe) to Phase III (most capable), guiding both educational planning and therapy targets.

🎓 CVI in School: What Parents Must Know and What to Put in the IEP

School is where Cortical Visual Impairment Awareness Month most directly translates into action. And school is where the CVI support gap is most damaging.

Early detection of CVI is crucial so that children can engage more fully in school, activities of daily living, vocational pursuits, and recreational activities. (Source: Ophthalmology Times, March 2026)

Evidence-Based Classroom Strategies for Children with CVI

Strategy	Why It Helps	How to Implement
Reduce visual clutter	Cluttered environments overwhelm the CVI visual brain	Plain backdrops for materials; remove busy wall displays near work area
Use high-contrast materials	Easier for the CVI brain to process	Black/white or bright solid colour worksheets
Favour red and yellow	Most reliably processed by CVI visual systems	Red/yellow target objects; colour-coded key materials
Use movement	Moving stimuli detected more easily	Introduce objects with slight movement before presenting static
Allow extra response time	Visual latency means brain needs more processing time	Wait 5–10 seconds after presenting visual information
Consistent lighting	Flickering or glare-heavy environments worsen processing	Even lighting; no windows directly behind materials
Single-item presentation	Multiple objects overwhelm visual processing	Present one item at a time rather than arrays
Familiar materials first	Novelty suppresses CVI visual response	Always start with highly familiar items; introduce new items slowly

(Source: Perkins School for the Blind — CVI Resources | American Academy of Ophthalmology)

What to Request in an IEP for a Child with CVI

If your child has been diagnosed with CVI — or if you suspect CVI — here is what to request specifically in their Individualised Education Programme (IEP) during Cortical Visual Impairment Awareness Month:

• ✅ Formal CVI-specific functional vision assessment by a Teacher of the Visually Impaired (TVI) with CVI training
• ✅ CVI Phase identification (Phase I, II, or III) to guide all educational planning
• ✅ Learning media assessment — determines whether print, braille, or other formats are appropriate
• ✅ Environmental modifications documented in the IEP as legally binding
• ✅ Related services — low vision instruction, assistive technology, and occupational therapy
• ✅ Staff training — ALL class staff, not just the specialist, should understand CVI
• ✅ Annual reassessment — CVI presentations change with development; the IEP must keep up

💔 A Parent Story That Belongs to This Month

Meet Nadia. She is the mother of a 7-year-old daughter named Sofia who has cerebral palsy. From the time Sofia was an infant, Nadia noticed something: Sofia would stare at the window rather than at her face. She reached inaccurately for toys. She seemed to see things in some environments but not others.

Every specialist Nadia saw focused on the cerebral palsy. “Her vision seems fine for her condition,” she heard repeatedly. Sofia passed every standard eye test.

At age 5, following a Cortical Visual Impairment Awareness Month post she found online in September, Nadia specifically requested a CVI functional vision assessment. The assessment confirmed Phase II CVI — severe enough to significantly affect Sofia’s learning, but entirely invisible to every standard assessment she had ever received.

Sofia’s classroom was adapted with a high-contrast, low-clutter environment. Her therapy team learned to use red objects in her visual field. Her teaching assistant learned to wait 8 seconds after presenting visual information before assuming Sofia hadn’t seen it.

“For five years, she had been working twice as hard as anyone realised,” Nadia says. “And for five years, everyone thought her responses to the world were just cerebral palsy. September — CVI Awareness Month — gave me the words to ask the right question. And that question changed everything.”

Sofia is now in Phase III CVI — the most capable phase. Her reading is developing. She navigates her school with independence she never had before.

❓FAQs: Cortical Visual Impairment Awareness Month 2026

Q: When is Cortical Visual Impairment Awareness Month 2026?

September has been declared CVI Awareness Month. (Source: Paths to Literacy) It runs throughout all of September 2026 — from September 1 to September 30 — and is dedicated to raising awareness about CVI as the leading cause of childhood visual impairment.

Q: What is cortical visual impairment?

CVI is a neurodevelopmental disorder characterised by deficits of visual function and functional vision caused by neurological damage to visual pathways and processing areas in the brain. (Source: Children’s Hospital Los Angeles) In simple terms: the eyes work, but the brain cannot properly interpret what they see.

Q: Can a child with CVI pass a standard eye test?

Yes — and this is one of the most critical CVI facts. Comprehensive eye exams characteristically produce no signs of CVI in normal eyes with normal functional issues or challenges with visual acuity and/or contrast sensitivity. (Source: UNC Kittner Eye Center) This is why standard eye tests miss CVI — and why a CVI-specific functional vision assessment by a trained specialist is essential.

Q: What is the NIH CVI Registry and why does it matter?

The NIH CVI Registry aims to gain insights into current diagnostic and rehabilitation practices, characterise various presentations of CVI, and facilitate further research into the condition. (Source: NIH) It is the most significant step forward in CVI research — and families can learn more at cvi.nih.gov.

Q: How is CVI diagnosed in children?

Routine vision screenings may miss CVI; clinicians should consider medical history and behavioural characteristics for diagnosis. (Source: AAP / Ophthalmology Times) CVI requires a functional vision assessment by a specialist — ideally a Teacher of the Visually Impaired with CVI training — alongside review of the child’s neurological history.

Q: Can children with CVI improve?

Yes — with the right early intervention, children with CVI can make real progress. Future research aims to show the neurophysiological basis of neuroplasticity in the developing brain of individuals with CVI — meaning the brain’s capacity to adapt and improve visual processing with appropriate stimulation. (Source: Ophthalmology Times, 2026) The key is identifying CVI early and designing visual environments that meet the child’s specific visual processing profile.

Q: What should I do if I suspect my child has CVI?

Contact your paediatrician and ask specifically for a referral to a paediatric ophthalmologist or specialist in CVI functional vision assessment. Do not rely on a standard optometry visit. Clarifying the factors for suspecting CVI should help build awareness and help eye care providers identify children for further assessment so they can benefit from rehabilitation and accommodation strategies as early as possible.
