Retinoblastoma Signs in Babies
Content reviewed against published NIH, AAP guidelines
Last reviewed:
If your baby has been diagnosed with or you suspect retinoblastoma signs in babies, here is what the evidence says.
The short answer
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.

“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.
By Age
What to expect by age
0-3 months
Retinoblastoma can be present at birth, especially in the hereditary bilateral form (affecting both eyes). The most important early sign is leukocoria — a white pupil reflex instead of the normal red reflex, which may be noticed in photographs or by a doctor during the red reflex test at well-child visits. Babies with a family history of retinoblastoma should have a dilated eye exam by a pediatric ophthalmologist within the first weeks of life.
3-6 months
As the tumor grows, leukocoria may become more noticeable. Other signs can include strabismus (a crossed or misaligned eye), a red or irritated eye, or poor vision in one eye (the baby may not track objects equally). Regular red reflex screening at well-child visits is a critical screening tool. If you notice a white glow in your baby's eye in photographs, bring this to your pediatrician's attention immediately.
6-12 months
Retinoblastoma can be diagnosed at any point in this age range. Treatment depends on the size, location, and whether one or both eyes are affected. Options include laser therapy, cryotherapy, chemotherapy (systemic, intra-arterial, or intravitreal), and in some cases, removal of the eye (enucleation) when necessary to save the child's life. The goal is always to save life first, preserve the eye second, and maintain vision third.
12 months+
Children treated for retinoblastoma need long-term follow-up with regular eye exams, particularly during the first 5 years of life when recurrence risk is highest. Children with the hereditary form (bilateral or with a family history) have a higher risk of second cancers later in life and need ongoing surveillance. With successful treatment, most children adapt well and lead full, active lives, even if vision in one eye is reduced or one eye was removed.
What Should You Do?
When to take action
- Your baby has a normal red reflex in both eyes at well-child visits
- A single photo showed an unusual reflection but your pediatrician confirmed a normal red reflex exam
- Your baby tracks objects equally with both eyes and has no white pupil visible
- Your baby with a family history of retinoblastoma has normal dilated eye exams
- You notice a white glow or reflection in one of your baby's eyes in flash photographs
- Your baby's eyes appear misaligned or one eye turns inward or outward
- You have a family history of retinoblastoma and want to ensure proper screening
- You consistently see a white pupil (leukocoria) in your baby's eye in photos or in person — request an urgent referral to a pediatric ophthalmologist
- Your baby has a rapidly changing eye appearance with redness, swelling, or apparent pain combined with a white pupil

Bottom line
Most cases of retinoblastoma signs in babies are normal. Talk to your pediatrician if you consistently see a white pupil (leukocoria) in your baby's eye in photos or in person — request an urgent referral to a pediatric ophthalmologist.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

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.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Agenesis of the Corpus Callosum (ACC)
Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
