Some newborns have less of the white of the eye on the side of the nose, and the inner canthus is more serious and obvious, so it looks like the two eyes are looking towards the middle. As the newborn grows up, the nasal bridge grows higher, the inner canthus will probably improve, and the situation of the opposite eye will slowly disappear or improve. If congenital internal strabismus is not treated, it will affect the child’s vision or the normal development of visual function and cause irreparable damage.
