This was cross sectional study done in Khartoum state- Sudan in the period from July to December 2018. The aimed of the study was to measure of Fetal Binocular Distance (BOD), Ocular Distance (OD) and Interocular Distance (IOD) in Second & Third Trimester of Pregnancy in correlation to Gestational Age using Ultrasonography. 107 normal singleton pregnant women in Second & Third trimester of Pregnancy with a mean age of (26.5 years) were included. The data were collected by data collection sheet including the study variables which were gestational age (last menstrual period, femur length, biparietal diameter head circumference, abdominal circumference),ocular diameter (OD), Binocular distance (BOD) in mm, interorbital diameter (IOD), fetal weight in gram after the verbal consent was taken from all pregnant women then analyzed by statistical package for social sciences. The study found strong significant correlations between BOD per mm, OD per mm and IOD per mm with gestational age (LMP, FL, BPD, AC and HC). BOD had greater values than did the IOD and OD. The BOD displayed a greater value of correlation coefficient (r= 0.879, 0.884, 0.886, 0.877 and 0.885 respectively), OD with above mention fetal biometry respectively (r= 0.800, 0.800, 0.800, 0.796 and 0.796 respectively) and IOD (r = 0.593, 0.605, 0.605, 0.591, 0.607, 0.796 with above mention fetal biometry respectively) p value of all <0.01. The study concluded fetal orbital measurement was interested and useful in predicting gestational age, therefore the study recommended using orbital measurements to estimate fetal age.
