Evaluation of longitudinal changes in choroidal thickness during pregnancy and postpartum using widefield swept-source optical coherence tomography.

ABSTRACT: In this exploratory study, we investigated longitudinal changes in whole, luminal, and stromal choroidal thickness (CT) during pregnancy and the postpartum period using widefield swept-source optical coherence tomography. Ten eyes of five healthy pregnant women were examined monthly from mid-pregnancy to delivery and, when possible, at least 1 year postpartum. CT was measured over a 20 × 23 mm area centered on the fovea and was analyzed using a grid of three concentric subfields defined by circles measuring 3, 9, and 18 mm in diameter. At 5 months' gestation, the mean central CT was 258 ± 35 μm. For the right eye, the mean CT within the entire 18-mm circle showed a nonsignificant increase between 4 and 5 months of gestation (P = 0.078), followed by a significant decrease between 5 and 9 mo
