title: Peripapillary choroidal thickness in healthy Turkish subjects.
abstract: OBJECTIVE
  The objective of the study reported here was to investigate the normal peripapillary choroidal thickness (CT), measured by enhanced depth imaging optical coherence tomography (EDI-OCT), in healthy Turkish volunteers.
  
  
  METHODS
  In this prospective cross-sectional study, 57 eyes of 57 healthy Turkish subjects were enrolled. Each participant underwent a comprehensive ophthalmic examination and peripapillary CT measurement using EDI-OCT.
  
  
  RESULTS
  The mean age of the 25 female and 32 male patients in the study was 30.9±10.6 years (range, 18-56 years). The mean peripapillary CT at the superior, inferior, nasal, and temporal sites was 225±57, 183±47, 220±57, and 233±59 μm, respectively. The inferior peripapillary CT value was significantly lower than the peripapillary CT values (P<0.001 for all), whereas no significant differences were found between the superior, nasal, and temporal peripapillary CT values.
  
  
  CONCLUSIONS
  The findings of the study revealed that Turkish people had significantly lower peripapillary CT values in the inferior quadrant than in the superior, nasal, and temporal quadrants.
