Gestational age assessment by the lens examination method in normal and pathological pregnancies.
The anterior vascular capsule of the lens was examined in 100 premature infants. It was found that the normal embryological process of gradual disappearance of the anterior vascular capsule between 27 and 34 weeks of gestation is not significantly influenced by maternal and fetal high risk factors, nor by maternal drug intake. It seems that lens examination could be regarded as a good method of gestational age estimation between the 27th and 34th week of gestation.
