Why are baby's eyes yellow?

We all know that the eyeballs are generally black, but there will be abnormalities in the eyes of newborns. The most typical example is yellow eyes. This kind of change in children of this period will definitely make family members worried, and they will pay close attention to the possible causes and effects of yellow eyes in babies. So, what’s the matter with the baby’s yellow eyes? Let’s take a closer look below.

Jaundice is a common symptom and sign, which occurs due to increased serum bilirubin concentration caused by bilirubin metabolism disorders. Clinically, the sclera, mucous membranes, skin and other tissues are stained yellow. Because the sclera contains more elastin and has a stronger affinity with bilirubin, the yellowing of the sclera in patients with jaundice is often noticed first before the mucous membranes and skin. When the total serum bilirubin is between 17.1 and 34.2 μmol/L, but jaundice is not visible to the naked eye, it is called latent jaundice or subclinical jaundice. When the total blood bilirubin concentration exceeds 34.2 μmol/L, jaundice can be found clinically, which is also called overt jaundice.

Neonatal jaundice is a special physiological phenomenon. Among normal newborns, about 50%-70% of infants will develop jaundice on the 2nd to 3rd day after birth. It usually first appears on the face and neck, then spreads to the trunk and limbs. The sclera may also be slightly yellowed. Generally, the jaundice becomes lighter in 7-10 days and disappears completely in about 2 weeks. Jaundice in premature babies can last longer, which is called physiological jaundice. Various acute and chronic diseases can aggravate and prolong physiological jaundice, so these diseases should be treated actively. If jaundice persists for more than two weeks, reappears or progressively worsens, and the serum bilirubin concentration exceeds 205.2mmol/L (12mg/dl), it is pathological jaundice and medication should be used under the guidance of a doctor.

The above is an introduction to what causes yellow eyes in babies. Parents should have a clearer idea of ​​it. The main reason for children's yellow eyes is jaundice. The diagnosis should be based on other symptoms of the child's body. Once the child is ill, he or she should be taken to a regular hospital for diagnosis and treatment in time to prevent more serious harm to the child.
