From: Assessing progression limits in different grades of keratoconus from a novel perspective: precision of measurements of the corneal epithelium

Fig. 2

TRT values for repeatability at different stages of keratoconus measured by observer 1 (a) and observer 2 (b). TRT, test-retest repeatability (2.77 Sw); CET, central epithelium thickness; TET, thinnest epithelium thickness; S1 (S3), corneal apex superior at 1 mm (3 mm); I1 (I3), corneal apex inferior 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)
