If your baby has been diagnosed with or you suspect cortical visual impairment (cvi) in babies, here is what the evidence says.
The short answer
Cortical visual impairment (CVI) is the most common cause of visual impairment in children in developed countries. Unlike eye-based vision problems, CVI is caused by damage or differences in the brain's visual processing areas, often related to prematurity, hypoxic-ischemic encephalopathy (birth asphyxia), or other neurological conditions. A hallmark of CVI is variable visual ability -- your baby may seem to see well sometimes and poorly other times. With appropriate early intervention and visual stimulation strategies, many children with CVI show significant improvement in functional vision over time.

- Usually normal when: Your baby tracks faces and objects smoothly and consistently by 2-3 months of age
- Call your doctor if: Your newborn has no visual response to bright lights or faces and you have not yet had an eye exam -- seek evaluation promptly to determine the cause
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, AFB, Perkins School for the Blind guidelines, cortical visual impairment (CVI) is the most common cause of visual impairment in children in developed countries. Unlike eye-based vision problems, CVI is caused by damage or differences in the brain's visual processing areas, often related to prematurity, hypoxic-ischemic encephalopathy (birth asphyxia), or other neurological conditions. A hallmark of CVI is variable visual ability -- your baby may seem to see well sometimes and poorly other times. With appropriate early intervention and visual stimulation strategies, many children with CVI show significant improvement in functional vision over time. At 0-3 months, cVI may be suspected if your baby does not fixate on faces, does not track objects, or seems to look past or through you. However, early detection can be challenging because typical newborn visual skills are limited. Babies at high risk for CVI include those with a history of prematurity, hypoxic-ischemic encephalopathy, periventricular leukomalacia, hydrocephalus, or seizures. An ophthalmological exam may show normal or near-normal eye structures, which is the key clue that the visual problem is brain-based. It is generally considered normal when your baby tracks faces and objects smoothly and consistently by 2-3 months of age. However, you should contact your pediatrician promptly if your newborn has no visual response to bright lights or faces and you have not yet had an eye exam -- seek evaluation promptly to determine the cause.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
CVI may be suspected if your baby does not fixate on faces, does not track objects, or seems to look past or through you. However, early detection can be challenging because typical newborn visual skills are limited. Babies at high risk for CVI include those with a history of prematurity, hypoxic-ischemic encephalopathy, periventricular leukomalacia, hydrocephalus, or seizures. An ophthalmological exam may show normal or near-normal eye structures, which is the key clue that the visual problem is brain-based.
3-6 months
By this age, most babies should be tracking faces and objects, reaching for toys, and making eye contact. If your baby has CVI, you may notice they prefer looking at bright, single-colored objects (especially red and yellow), look at objects in their peripheral vision rather than straight ahead, or are overwhelmed in visually busy environments. Light-gazing, where your baby stares at lights, is common in CVI. An evaluation by a pediatric ophthalmologist and a teacher of the visually impaired can help establish a CVI diagnosis and range score.
6-12 months
Early intervention is critical for children with CVI. A vision teacher experienced in CVI can design strategies to improve your baby's functional vision. These include presenting objects against a plain black background, using preferred colors, reducing visual clutter in the environment, allowing extra time for visual processing, and using movement to attract visual attention. Many children with CVI show improvement with consistent intervention, and functional vision can continue to develop throughout childhood.
12 months+
As your child grows, improvements in CVI may include better visual attention, ability to recognize familiar objects and people, and more consistent visual responses. Your child's educational team should include a teacher of the visually impaired and possibly an orientation and mobility specialist. CVI is assessed on a range from Phase 1 (minimal visual response) to Phase 3 (near-typical visual function with some characteristic differences). Many children progress along this range with intervention, though the rate and extent of improvement vary.
What to Tell Your Pediatrician
- Describe when you first noticed cortical visual impairment (cvi) in babies and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby does not consistently track objects or make eye contact by 3-4 months of age.
- Mention if your baby seems to see better on some days than others, or in some environments but not others.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby tracks faces and objects smoothly and consistently by 2-3 months of age
- Your baby makes eye contact and smiles at familiar faces
- Your baby reaches for toys they can see by 4-5 months
- Eye exams have been normal with no structural eye problems
- Your baby does not consistently track objects or make eye contact by 3-4 months of age
- Your baby seems to see better on some days than others, or in some environments but not others
- Your baby stares at lights frequently or seems to look at objects from the side rather than straight on
- Your baby was premature or had a neurological event and is not meeting visual milestones
- Your newborn has no visual response to bright lights or faces and you have not yet had an eye exam -- seek evaluation promptly to determine the cause
- Your baby who was previously tracking and making eye contact suddenly loses these abilities, which could indicate a new neurological event requiring urgent evaluation
What You Can Do at Home
- Keep track of when you notice cortical visual impairment (cvi) in babies — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby tracks faces and objects smoothly and consistently by 2-3 months of age — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if your newborn has no visual response to bright lights or faces and you have not yet had an eye exam -- seek evaluation promptly to determine the cause.
Related Conditions
Congenital Cataracts
Congenital cataracts are cloudiness in the lens of the eye that is present at birth, occurring in approximately 1 in 2,500 live births. They can affect one or both eyes and range from small opacities that do not affect vision to dense cataracts that completely block light. Dense congenital cataracts are a medical urgency because they can cause irreversible amblyopia (lazy eye) if not treated promptly. Surgery to remove the cataract is the primary treatment and may need to be performed within the first few weeks of life for the best visual outcome.
Retinoblastoma Signs in Babies
Retinoblastoma is a rare eye cancer that develops in the retina, primarily affecting children under age 5, with most cases diagnosed before age 3. It affects about 1 in 15,000 to 20,000 children. The most common sign is a white glow (leukocoria) in the pupil, often first noticed in flash photographs. When detected and treated early, survival rates exceed 95%, and many children retain useful vision.
Baby Blocked Tear Duct (Watery Eye)
A blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes watery eyes and sometimes sticky discharge because tears cannot drain normally through the narrow duct into the nose. The good news is that about 90% of blocked tear ducts resolve on their own by age 12 months without any procedure.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
