Abstract

Purpose: 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®, Pentacam®, and Spectralis optical coherence tomography (OCT) to evaluate the clinical usefulness of UBM in the sitting position.

Methods: We evaluated 92 eyes in 47 healthy adults. ACD was measured by IOL Master®, Pentacam®, and UBM. ACA was measured using Pentacam®, UBM, and Spectralis OCT. UBM was performed in the sitting position using bag/balloon technology. Measured values were compared statistically.

Results: ACD measured by IOL Master®, Pentacam®, and UBM was 3.57 ± 0.32 μm, 3.64 ± 0.33 μm and 3.51 ± 0.32μm, respectively. UBM measurements of ACD were significantly shallower than with the other methods (p < 0.001). The results among the 3 methods were strongly correlated (r > 0.8, p < 0.05 in all groups). Mean ACA of 4 directions was not significantly different among the 3 methods (p > 0.05). There was strong correlation between UBM and Spectralis OCT (r = 0.957) but moderate correlation between Pentacam® and UBM and Pentacam® and Spectralis OCT (r = 0.557, 0.571, respectively, p < 0.05). Specifically, ACA of the superior quadrant showed a low correlation between Pentacam® and UBM and Pentacam® and Spectralis OCT (r = 0.257, 0.295, respectively).

Conclusions: ACD measured by UBM in the sitting position was shallower compared to the other methods; however, ACD measured by IOL Master®, Pentacam®, and UBM showed significant correlations among the methods. The mean ACA measured by Pentacam®, 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.
