Morphometric Measurements of Fetal and Neonatal Eyes Using MRI and Ultrasound

Abstract

Using MRI, the ratios of the anterior posterior (AP) lengths of the eyes versus the AP lengths of the corneae to the external occipital protuberances were found to decrease from 28 weeks of gestation onwards, while the ratios of the transverse diameters of the eyes versus the transverse diameters of the zygomatic bone to the nasal cavity increased till term. No further change in the ratios of the AP or transverse diameters was observed even till three years of age.
