Abstract:
Objective To compare the differences,correlation,and consistency among central corneal thickness (CCT) measurements by anterior segment optical coherence tomography (AS-OCT),Lenstar,and ultrasound biomicroscopy (UBM). Methods In this cross-sectional study,AS-OCT,Lenstar,and UBM were used to measure the CCT in 54 patients (83 eyes) between October 2015 and August 2016 in the Fourth Affiliated Hospital of China Medical University. Data were statistically analyzed by random analysis of variance, Pearson correlative analysis,and Bland-Altman analysis to compare the difference,correlation,and consistency among the three instruments. Results The differences in the mean CCT measured by the three instruments were statistically significant (P < 0. 05 for all comparisons). There was also a high correlation (all P < 0. 001) and consistency among the three instruments. Conclusion There is a high level of correlation and consistency in the CCT measurements by the three instruments. Therefore,these could be interchangeable under some circumstances. AS-OCT could be the first choice as an early screening tool for glaucoma.
