Purpose
To assess the corneal layers thickness in healthy young adults using spectral‐domain anterior segment optical coherence tomography (AS‐OCT).
Methods
There were 86 eyes of 86 healthy volunteers, 55 females and 31 males, which were included in the study. The mean age ± standard deviation (SD) was 22.87 ± 3.90 years (range, 20–43). Spectral‐domain AS‐OCT was performed using Spectralis OCT (Spectralis; Heidelberg Engineering, Heidelberg, Germany). Measurements of central corneal thickness, and central thickness of epithelium, Bowman's layer, stroma and the complex Descemet‐endothelium were performed.
Results
Mean central corneal thickness, epithelium, Bowman, stroma and Descemet‐endothelium were 555.50 ± 29.64 µm (range 510–624), 54.60 ± 4.25 µm (range 45–63), 16.70 ± 1.73 µm (range 14–20), 467.51 ± 28.91 µm (range 420–533) and 16.74 ± 1.66 µm (range 14–20), respectively.
Conclusions
Spectralis OCT can be easily used to non‐invasive measurements of the anterior segment parameters and this study establishes a normal database for corneal thickness and all its layers in healthy young adults.
