To evaluate choroidal thickness or choroidal structure of pregnant women from first trimester to third trimester using optical coherence tomography (OCT).
This prospective study included 28 eyes of 14 healthy pregnant women. Central choroidal thickness was measured using enhanced depth imaging OCT (EDI-OCT). The ratio of the luminal area to the stromal area was also assessed using binarization of the images obtained by EDI-OCT. The association of CCT with age, central retinal thickness (CRT), axial length (AL), or refractive error (RE) were analyzed.
The mean CCT was 276±91μm, 304±98μm and 293±90μm at first, second and third trimester of pregnant women, respectively. The mean CCT significantly increased from first trimester to second and third trimester of pregnancy (P<.0001 and P<.0001). The mean ratio of choroidal luminal area was similar at first, second and third trimester of pregnant women (64.3±2.0%, 64.2±3.3% and 64.9±3.8%, respectively). In the multivariate analysis, there was no associating factors with CCT in each pregnant stage.
The CCT significantly increased from first trimester to second and third trimester of pregnancy. Multiple analysis found no factors associated with CCT.
