A retrospective analysis of 123 healthy eyes was performed. Age, gender, refractive state and spheric equivalencies were noted. Subfoveal choroidal thickness was measured and noted manually by two independent observers. A total of 72 patients (123 eyes) were included in this study. The mean age of the patients was 47.47 (15-84). The mean spheric equivalent of the refractive error was -0.24 D. According to LogMAR, the mean visual acuity was -0.006. The mean subfoveal choroidal thickness was 280.23 µm (SD ± 81.15, range 124-527 µm). The choroidal thickness showed a negative correlation with age for the subfoveal location (p = 0.000a). Regression analysis showed that subfoveal choroidal thickness decreased 3.14 µm for each year of age. The regression formulation was choroidal thickness = 429 - 3.14 × age. When we compared eyes according to their spheric equivalencies, there was no statistically significant correlation between spheric equivalency and subfoveal choroidal thickness. (p = 0.14). In this study, we report choroidal thickness measurement among healthy eyes within the Turkish population to demonstrate that EDI-OCT imaging can give cross-sectional information regarding the choroid, thereby facilitating quantitative imaging. © 2013 Springer Science+Business Media.eninfo:eu-repo/semantics/closedAccessChoroidal thicknessEnhanced depth imagingOptic coherence tomographyArticle40123912690Q23534
