Abstract:
PURPOSE: To compare the accuracy and clinical usefulness of different devices by measuring anterior chamber depth (ACD) with three devices and central corneal thickness (CCT) with four devices. METHODS: In 180 eyes of 90 healthy subjects, ACD was measured using A-scan, Lenstar LS900®, Pentacam®, and CCT was measured using ultrasound pachymetry (USP), Lenstar LS900®, Pentacam®, and anterior segment optical coherence tomography (OCT). RESULTS: The average ACT measurements using Lenstar LS900®, A-scan, and Pentacam® were 3.27 ± 0.35 mm, 3.26 ± 0.36 mm, and 3.25 ± 0.36 mm, respectively. The measurements were significantly correlated (p < 0.001) but without statistically significant difference (p = 0.017). The Bland-Altman plots showed a low degree of agreement. The average CCT measurements using Pentacam®, USP, Lenstar LS900®, and OCT were 553.31 ± 25.23 µm, 547.26 ± 23.83 µm, 541.38 ± 24.49 µm, and 531.40 ± 22.33 µm, respectively. The measurements were significantly correlated (p < 0.001) and statistically significantly different (p < 0.05). The Bland-Altman plots showed a low degree of agreement. CONCLUSIONS: ACD and CCT measured using different devices were highly correlated, but the ACD measurements were not statistically different; however, the CCT measurements were statistically different, and agreement was low between both measurements.
