If your baby has been diagnosed with or you suspect red eye from birth (subconjunctival hemorrhage), here is what the evidence says.
The short answer
A subconjunctival hemorrhage (a bright red patch on the white of the eye) in a newborn is a common and harmless result of pressure during delivery. It is caused by tiny blood vessels breaking in the eye during the birth process. It does not affect your baby's vision, causes no pain, and resolves on its own within 1-3 weeks without treatment.
Key takeaways
- A subconjunctival hemorrhage (a bright red patch on the white of the eye) in a newborn is a common and harmless result of pressure during delivery. It is caused by tiny blood vessels breaking in the eye during the birth process. It does not affect your baby's vision, causes no pain, and resolves on its own within 1-3 weeks without treatment.
- Usually normal when: A flat, bright red patch on the white of the eye present at birth or shortly after delivery
- Call your doctor if: Red eye with significant swelling of the eyelid, pus-like discharge, or the baby unable to open the eye, which could indicate an eye infection
- 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.”

What Parents Should Know
According to AAP, NIH guidelines, a subconjunctival hemorrhage (a bright red patch on the white of the eye) in a newborn is a common and harmless result of pressure during delivery. It is caused by tiny blood vessels breaking in the eye during the birth process. It does not affect your baby's vision, causes no pain, and resolves on its own within 1-3 weeks without treatment. At 0-1 month, subconjunctival hemorrhages are common after vaginal delivery, especially after prolonged pushing, vacuum-assisted delivery, or forceps use. The bright red patch on the white of the eye can look alarming but is completely benign. It is simply blood from a tiny broken blood vessel trapped under the clear membrane covering the eye (conjunctiva). It does not affect vision, does not cause pain, and requires no treatment. The blood gradually reabsorbs over 1-3 weeks, sometimes changing from red to yellow before disappearing completely. It is generally considered normal when a flat, bright red patch on the white of the eye present at birth or shortly after delivery. However, you should contact your pediatrician promptly if red eye with significant swelling of the eyelid, pus-like discharge, or the baby unable to open the eye, which could indicate an eye infection.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
Subconjunctival hemorrhages are common after vaginal delivery, especially after prolonged pushing, vacuum-assisted delivery, or forceps use. The bright red patch on the white of the eye can look alarming but is completely benign. It is simply blood from a tiny broken blood vessel trapped under the clear membrane covering the eye (conjunctiva). It does not affect vision, does not cause pain, and requires no treatment. The blood gradually reabsorbs over 1-3 weeks, sometimes changing from red to yellow before disappearing completely.
1-3 months
The hemorrhage should have fully resolved by this time. If a new red spot appears in the eye at this age, it is likely unrelated to birth and may be caused by crying, coughing, or straining. These are also typically harmless and self-resolving.
3-6 months
Birth-related subconjunctival hemorrhages are long resolved. New ones can occur at any age from straining or coughing and are generally benign.
6-12 months
Any eye redness at this age is unrelated to birth. Red eyes with discharge may indicate conjunctivitis. A blood spot in the white of the eye from crying or coughing is typically harmless.
What to Tell Your Pediatrician
- Describe when you first noticed red eye from birth (subconjunctival hemorrhage) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if the hemorrhage does not resolve within 3 weeks.
- Mention if you notice new red spots in the eyes appearing frequently without obvious cause.
- 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
- A flat, bright red patch on the white of the eye present at birth or shortly after delivery
- The red patch does not cause tearing, discharge, or swelling
- Baby is not bothered by it and can open the eye normally
- The patch gradually fades over 1-3 weeks
- The hemorrhage does not resolve within 3 weeks
- You notice new red spots in the eyes appearing frequently without obvious cause
- You want reassurance that the red patch is not affecting vision
- Red eye with significant swelling of the eyelid, pus-like discharge, or the baby unable to open the eye, which could indicate an eye infection
- Blood visible in the colored part of the eye (iris) or pupil appearing irregular, which requires urgent ophthalmologic evaluation
What You Can Do at Home
- Keep track of when you notice red eye from birth (subconjunctival hemorrhage) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that a flat, bright red patch on the white of the eye present at birth or shortly after delivery — this is generally within the range of normal.
- At 0-1 month, 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 red eye with significant swelling of the eyelid, pus-like discharge, or the baby unable to open the eye, which could indicate an eye infection.
Related Conditions
Newborn Eye Swelling After Birth
Mild eye swelling and puffiness in newborns is very common after birth, especially after vaginal delivery, and typically resolves within a few days. It can also be caused by the prophylactic antibiotic eye ointment given after birth. However, significant swelling with yellow or green discharge, especially after the first few days, may indicate a bacterial infection (ophthalmia neonatorum) that requires prompt treatment.
Bruising After Difficult Delivery
Bruising from delivery is common, especially after difficult or prolonged labors, vacuum-assisted deliveries, or forceps deliveries. The bruising typically appears on the face, scalp, or body and resolves on its own within 1-2 weeks. Birth-related bruising can contribute to newborn jaundice as the blood breaks down, so your baby's bilirubin levels may be monitored.
Eye Infection and Discharge in Newborns (Conjunctivitis)
Eye discharge in newborns is common and can be caused by a blocked tear duct (most frequent), chemical irritation from eye prophylaxis, or infection. While most sticky eyes are harmless, any significant redness, swelling, or pus-like discharge in the first month should be evaluated promptly, as certain infections can damage the eye.

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.
