title: Evaluation of subfoveal choroidal thickness in pregnant women using enhanced depth imaging optical coherence tomography.
abstract: OBJECTIVE
  To evaluate the subfoveal choroidal thickness (SFCT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in pregnant women.
  
  
  METHODS
  In this prospective and cross-sectional study, 100 pregnant women and 100 age-matched nonpregnant women were enrolled. The SFCT was measured by EDI-OCT. The refractive error, intraocular pressure (IOP), axial length (AL), central corneal thickness (CCT), systolic and diastolic blood pressure, and ocular perfusion pressure (OPP) were also measured. Pregnancy-related factors including gestational age, maternal weight gain, and fetal weight were noted.
  
  
  RESULTS
  Mean SFCT was 371.1 ± 61.8 µm in the study group and 337.2 ± 62.4 µm in the control group (p < 0.001). No significant correlation was found between SFCT and spherical refraction, IOP, AL, CCT, OPP, gestational age, maternal weight gain, or fetal weight.
  
  
  CONCLUSIONS
  Our results suggest that subfoveal choroidal thickness increases in pregnant women compared with age-matched nonpregnant women.
