| dc.description.abstract | ABSTRACT Background: Fetal biometry, typically using parameters like biparietal diameter (BPD), Head circumference (HC), abdominal circumference (AC), and Femur length (FL), estimate gestational age. Recent literature highlights the utility of orbital dimensions, particularly fetal binocular distance (FBD) for precise fetal gestational age estimation (FGAE). Due to a lack of published data on FBD in Nepal, this study aimed to fill this gap by assessing GA using FBD from 18th week in healthy women with uncomplicated pregnancies. Methods: Obstetric USG was performed in 288 women with uncomplicated pregnancy to evaluate the efficacy of FBD as a measure to calculate the predicted GA. GA ranged from 18 weeks to term. Only patients with known clinical GA, previous history of normal menstrual cycle, and who fit the inclusion criteria were included in the study. Results: The correlation between FBD in mm and gestational age (GA)in weeks was analyzed. The correlation was highly significant (r=0.987, p<0.001), assisting in compiling a nomogram of FBD and GA for Nepalese women. A highly significant correlation was also found between the FBD and other parameters as well. Conclusion: Fetal binocular distance correlates linearly with clinical gestational age and positively with other standard fetal biometry parameters such as biparietal diameter, head circumference, abdominal circumference, and femur length. Thus, fetal binocular distance proves to be a reliable parameter for determining gestational age. Keywords: Gestational age, Fetal Binocular distance (FBD), Ultrasonography (USG) | |
