Ocular biometry in full term newborn

ABSTRACT

This study was designed to re-evaluate the eye size and its measurements in fullterm newborns and to estimate these values in both sexes. Two hundred fullterm newborns [110 males and 90 females] delivered normally after a duration of 40.1 +/- 1.331 weeks gestational age were selected for this study. They were of birth weight 3.29 +/- 0.407 kgm, body length 51.1 +/- 2.08 cm and head circumference 34.59 +/- 1.565 cm. They were subjected to ocular ultrasound biometry for both eyes within one day after delivery. We found that, the mean axial length was 16.94 +/- 0.48 mm, the anterior chamber depth was 2.49 +/- 0.201 mm and lens thickness was 3.45 +/- 0.297 mm. There was a significant difference in these measurements between males and females in this sample of newborns
