In 1991 we conducted a refractive control test on 46 normal-born children and 31 under-born and new-born underweight men. The results are reported below. Subjects: preterm children refer to gestational age <37 weeks, birth weight ≤ 2500 grams; mild birth weight refers to the normal pregnancy and birth weight ≤ 2500 grams. The present study investigated 31 preterm infants and neonates with low birth weight (group A), weighing 1550 g to 2450 g at birth, including 15 males and 16 females. The control group (group B) 46 children, including 26 males and 20 females. Both groups were preschool-age children born at the same age, aged 4 to 5 years old.
