Fetal ocular biometry is a valuable resource for the evaluation of fetal growth and as a clue to the detection of congenital abnormalities during pregnancy. The purpose of the study was to sonographically estimate the gestational age using binocular diameter. This cross sectional study was carried out in the department of radiology of different hospital in Khartoum state, Sudan. Measurements were obtained only when the fetal face was directly perpendicular to the uterine wall, since measurements in an oblique plane were considered to be unreliable. The correlation between binocular distance (BD) in cm and gestational age (GA) in weeks was calculated. This correlation was highly significant (r = 0. 973; p<0.001). Excellent correlation was found to exist between binocular diameter and gestational age. In the absence of known date of last menstrual period or where fundal height does not agree with dates, these parameters are valuable in estimating the gestational age of the fetus.
