Aim: 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.
Materials and 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.
Conclusion: 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.
