<b>Purpose:</b> We compared the measurements of anterior chamber depth (ACD) and anterior chamber angle (ACA) using ultrasound biomicroscopy (UBM) in the sitting position compared with IOL Master<sup>Ⓡ, Pentacam<sup>Ⓡ, and Spectralis optical coherence tomography (OCT) to evaluate the clinical usefulness of UBM in the sitting position. <b>Methods</b>: We evaluated 92 eyes in 47 healthy adults. ACD was measured by IOL Master<sup>Ⓡ, Pentacam<sup>Ⓡ, and UBM. ACA was measured using Pentacam<sup>Ⓡ, UBM, and Spectralis OCT. UBM was performed in the sitting position using bag/balloon technology. Measured values were compared statistically. <b>Results</b>: ACD measured by IOL Master<sup>Ⓡ, Pentacam<sup>Ⓡ, and UBM was 3.57 ± 0.32 μm, 3.64 ± 0.33 μm and 3.51 ± 0.32 μm, respectively. UBM measurements of ACD were significantly shallower than with the other methods (<em>p</em> < 0.001). The results among the 3 methods were strongly correlated (<em>r</em> > 0.8, <em>p</em> < 0.05 in all groups). Mean ACA of 4 directions was not significantly different among the 3 methods (<em>p</em> > 0.05). There was strong correlation between UBM and Spectralis OCT (<em>r</em> = 0.957) but moderate correlation between Pentacam<sup>Ⓡ and UBM and Pentacam<sup>Ⓡ and Spectralis OCT (<em>r </em>= 0.557, 0.571, respectively, <em>p</em> < 0.05). Specifically, ACA of the superior quadrant showed a low correlation between Pentacam<sup>Ⓡ and UBM and Pentacam<sup>Ⓡ and Spectralis OCT (<em>r</em> = 0.257, 0.295, respectively). <b>Conclusions:</b> ACD measured by UBM in the sitting position was shallower compared to the other methods; however, ACD measured by IOL Master<sup>Ⓡ, Pentacam<sup>Ⓡ, and UBM showed significant correlations among the methods. The mean ACA measured by Pentacam<sup>Ⓡ, UBM, and Spectralis OCT showed no significant differences. Due to the high correlation of ACA measurements between UBM and Spectralis OCT in the present study, UBM is expected to be a good tool for measuring anterior segment parameters.
