Summary

The purpose of this study is to develop a novel, highly automated method of gestational age estimation at delivery combining anterior lens capsule vascularity (ALCV) and biophysical parameters appropriate for use in low income countries. The specific aims of the proposed study are: (1) To develop an algorithm to predict gestational age at delivery from 26 to 42 weeks' gestation with ALCV and key biophysical parameters (2)To evaluate the performance of ALCV and biophysical parameter-based gestational age estimates. Specifically, we hypothesize that the accuracy of the predictive algorithm will be comparable to commonly used measures of gestational age dating (±2 days) and have better precision (±14 days) than commonly used measures of gestational age dating.
