Figure 4. Comparison of CS and CCT between two investigators. Comparison of CS (A) and CCT (B) between two investigators: Two independent investigators evaluated transplants via the clinical score system and anterior segment spectral domain optic coherence tomography (ASOCT) images of the same animals on the indicated days after keratoplasty. The disagreement range using corneal thickness (CCT) measurements was lower in the CCT than using the clinical score (CS).
