摘要：Purpose To compare and analyze central corneal thickness (CCT) measurements and measurement repeatability according to the corneal thickness obtained with anterior segment optical coherence tomography (AS-OCT), ultrasound pachymetry (USP), and dual Scheimpflug imaging (Galilei G4 ® ). Methods CCT measurements obtained using AS-OCT, USP, and a dual rotating Scheimpflug camera in 120 eyes of 60 healthy subjects were compared and the repeatability was analyzed. Results The average CCT measurements using AS-OCT, USP, and a dual rotating Scheimpflug camera were 511.23 ± 37.16, 525.78 ± 39.22, and 531.43 ± 41.57 μm, respectively. The CCT measurement using dual rotating Scheimpflug imaging was statistically significantly thicker than that measured using AS-OCT ( p 0.900, p < 0.001). All three methods showed high repeatability (intraclass correlation coefficient ≥ 0.996) for intra-examiner CCT measurements. Conclusions The CCT measurement results using the three methods were significantly correlated and showed high repeatability. However, the AS-OCT measurement was significantly thinner than that obtained using a dual rotating Scheimpflug camera. CCT measurement with a dual rotating Scheimpflug camera is a better alternative for USP than AS-OCT. Therefore, CCT should be interpreted in the context of the instrument used.
