Abstract
Purpose: To evaluate the efficacy of swept source optical coherence tomography (SS-OCT) by comparing the measurement of
central corneal thickness (CCT) to the measurement obtained using Orbscan II, anterior segment optical coherence tomography
(AS-OCT) and ultrasound pachymetry.
Methods: One examiner measured the CCT in 65 eyes of 65 healthy subjects using Orbscan II, AS-OCT, SS-OCT and ultrasound
pachymetry. The mean values and correlations were analyzed.
Results: The average CCT measurements obtained using Orbscan II, AS-OCT, SS-OCT and ultrasound pachymetry were
534.83 ± 38.46, 517.80 ± 32.48, 528.22 ± 33.71 and 528.02 ± 34.90 μm, respectively. A significant linear correlation was observed
among Orbscan II, AS-OCT, SS-OCT and ultrasound pachymetry (r > 0.894, p < 0.001). There was no significant difference
between the SS-OCT and ultrasound pachymetry (p = 0.782).
Conclusions: The results of the 4 methods were significantly correlated and the SS-OCT reached a high level of agreement
when CCT was determined using ultrasound pachymetry. The CCT measurements using SS-OCT is a better alternative for ultrasound
pachymetry than Orbscan II and AS-OCT.
