Abstract
PURPOSE
To compare the measurements of central corneal thickness (CCT) obtained using two kinds of spectral domain optical coherence tomography (OCT), Pentacam®, and ultrasound pachymetry (USP). METHODS: CCT was measured by Cirrus OCT®, Spectralis OCT®, Pentacam®, and USP in 32 eyes from 32 subjects without ocular disease of the anterior segment. RESULTS: The average CCT measurements using Cirrus OCT®, Spectralis OCT®, Pentacam®, and USP were 549.2 ± 28.7 µm, 545.2 ± 25.4 µm, 554.0 ± 27.8 µm, and 548.4 ± 27.9 µm respectively. The measurements were significantly highly correlated with each other (Pearson's correlation coefficient r > 0.9, all p-values < 0.001), but were significantly different (p < 0.001). The CCT 95% limits of agreement between Cirrus OCT® and Spectralis OCT®, Cirrus OCT® and Pentacam®, Cirrus OCT® and USP, Spectralis OCT® and Pentacam®, and Spectralis OCT® and USP were 27.70 µm, 26.1 µm, 26.97 µm, 22.91 µm, 35.59 µm, and 32.15 µm, respectively. CONCLUSIONS: The CCT values measured using the four devices were highly correlated with each other, but the measurement using Pentacam® was significantly thicker than that using USP. The measurements of the two kinds of spectral domain OCT were similar to those using USP. Therefore, these differences should be considered in clinical use, and measurements cannot be considered interchangeable.
