Red Eye From Birth (Subconjunctival Hemorrhage)
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.

By Age
What to expect by age
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.
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.
Birth-related subconjunctival hemorrhages are long resolved. New ones can occur at any age from straining or coughing and are generally benign.
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 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

Related Medical Concerns
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.
