The Violin plots of epithelium thickness obtained with the spectral-domain optical coherence tomographer (SD-OCT)/Placido device at difference stages of keratoconus groups. a Epithelium thickness of central epithelium thickness (CET) and thinnest epithelium thickness (TET); b Epithelium thickness of I1 and I3; c Epithelium thickness of S1 and S3; d Epithelium thickness of N1 and N3; e Epithelium thickness of T1 and T3. I1 (I3), corneal apex inferior at 1 mm (3 mm); S1 (S3), corneal apex superior at 1 mm (3 mm); N1 (N3), corneal apex nasal at 1 mm (3 mm); T1 (T3), corneal apex temporal at 1 mm (3 mm); *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001, ****P ≤ 0.0001
