Objectives: To compare the eye axial length (AL), equatorial horizontal diameter (HD), and equatorial vertical diameter (VD) of normal eyes using a novel wide-angle, arc-scanning, ultrasound diagnostic device for wide-angle B-mode echography. Methods: In this cross-sectional study, wide-angle B-mode echography and magnetic resonance imaging (MRI) were conducted on 22 normal eyes; the AL, HD, and VD were measured. Results: The mean ALs were as follows: wide-angle B-mode echography, 25.22±1.47 mm and MRI, 25.24±1.46 mm; a significant correlation was observed between the two measurements (β=0.995 [0.976, 1.013]; p<0.001; 95% R2=1.00). The mean HDs were as follows: wide-angle B-mode echography, 22.33±0.84 mm and MRI, 22.55±0.90 mm; a significant correlation was observed between the two measurements (β=0.902 [0.750, 1.179]; p<0.001; 95% R2=0.81). The mean VDs were as follows: wide-angle B-mode echography, 22.77±0.91 mm; and MRI, 22.88±0.92 mm; a significant correlation was observed between the two measurements (β=0.966 [0.853, 1.097]; p<0.001; 95% R2=0.93). Conclusions: There were no significant differences in the measurements for each parameter by wide-angle B-mode echography and MRI. Therefore, wide-angle B-mode echography permits accurate visualization of ocular morphology.
