Abstract PURPOSE: To compare the CCT measurements of normal subjects obtained with Artemis2 and Ultrasound Biomicroscope (UBM).

METHODS: Prospective study of 61 right eyes (122 normal subjects) were measured by the Artemis2 followed by Ultrasound Biomicroscope (UBM). Results were compared statistically using ANOVA, paired T test, and limit of agreement Bland-Altman.

RESULTS: The CCT measurements with Artemis2 and UBM show a significant correlation (r=0.913, P<0.0001). However, the Artemis2 values for CCT were thicker than those provided by the UBM by an average of -24.83± 13.05 microns. The standard error of the mean difference was 1.6714 microns.

CONCLUSIONS: Artemis2 and Ultrasound Biomicroscope measurements of CCT were significantly correlated. However, the mean difference between the two instruments was 24.83micron, which may be due to technical aspects result from forces applied on the cup by the examiner during the UBM measurement to prevent leakage that may reault in flatting of the cornea.
