Red blood clots in the eyes of newborn babies may be caused by birth canal extrusion, trauma, conjunctivitis and other factors. 1. Extrusion of the birth canal: If the newborn baby is born in a normal delivery, it will usually be extruded by the mother’s birth canal during delivery, which may lead to a small amount of hemorrhage in the retina and conjunctiva, and thus the symptom of red blood clots in the eyes. 2. Trauma: If a newborn baby’s eye is accidentally hit, it may cause damage to the eyeball or the area around the eye, resulting in the symptom of red blood in the eye. 3. Conjunctivitis: If a newborn baby is born in a normal delivery, it is easy to be infected by the bacteria in the birth canal during the delivery process, which leads to redness and congestion of the eyes and the appearance of red blood clots. If the red blood clots in the eyes of newborn babies exist for a long time, they should consult a doctor in time and be treated with the help of a professional doctor.
