Comparison of ocular morphological measurement by wide-angle echography and magnetic resonance imaging

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
