Ocular biometry in fullterm newborns

ABSTRACT

This study was designed to evaluate parameters of eye size in fullterm newborns in our region of the world, and to compare these values for the two sexes. Two hundred fullterm infants [110 male, 90 female], born by uncomplicated vaginal delivery were subjected to an ophthalmological examination including ocular ultrasound biometry on both eyes within 24 hours after birth. The following data were elicited, expressed as mean +/- standard deviation duration of gestation 40.1 +/- 1.3 weeks, birth weight 3.29 +/- 0.407 kg; body length 51.1 +/- 2.08 cm; and head circumference 34.59 +/- 1.56 cm. Regarding the eye axial length 16.94 +/- 0.488 mm; depth of the anterior chamber 2.49 mm +/- 0.201 mm; and lens thickness 3.45 mm +/- 0.297 mm. There was a statistically significant difference in the measured parameters of eye size between male female innnfants in our sample. Our results did not significantly from those of surveys performed on other populations in the world
