My daughter is four months old, and her sclera appears faintly blue, not white. A doctor mentioned that a blue sclera might indicate anemia. Blue-green sclera is more common in infants, primarily due to the thin choroid, which allows the color of the choroid’s subchoroidal plexus pigment layer to be seen, resulting in a blue-green or purplish color. This is a physiological phenomenon and should not be a cause for concern. Newborns cannot follow a person’s movement with their eyes until about a month after birth; they usually start to fixate on familiar sounds, people, or objects after that. It is recommended that you observe your child for any other symptoms.
