The Effect of Pregnancy on Choroidal Thickness in Normal Pregnant Women

Purpose: To measure the effect of pregnancy on choroidal thickness in normal pregnant women. Methods: In this comparative longitudinal study, Choroidal thickness measured during each Trimester and 3 Months following Delivery in 23 healthy pregnant women. This measurement was performed using Enhanced depth imaging optical coherence tomography (EDI-OCT). Results: The thickness of choroid increased significantly in the Second and third trimester of pregnancy in comparison with first trimester but it decreased 3 months postpartum to the less than first trimester thickness in the most measured choroidal areas.(P=0.03) Conclusion: Our study shows that the thickness of choroid increased significantly during pregnancy. However, the thickness decreases 3 months following delivery to the level less than the pregnancy period
