Abstract

Purpose To compare the accuracy of central corneal thickness (CCT) measurements by the oculus pentacam scheimpflug system, with those obtained with the DGH ultrasound pachymeter (UP) and to assess the agreement between the two devices. Methods In a prospective study, measurement agreement was assessed in 984 eyes of 492 healthy subjects using both oculus pentacam and ultrasonic pachymetry at the Eye Consultants Center, Riyadh, Saudi Arabia. Result In the measurement agreement experiment, the mean CCT was 552.4 ± 37.0 μm with oculus pentacam and 544.1 ± 35.4 μm with ultrasonic pachymetry. Regression analysis showed a high correlation between the values obtained with both devices (r = 0.912, P < 0.001). Compared with UP, pentacam overestimated the CCT by a mean of 8.2 μm as demonstrated in a Bland-Altman plot. Conclusion the CCT measurements by the pentacam and UP are highly correlated. The pentacam agrees well with UP and is a reliable alternative to UP in CCT measurements.
