In 3D images, vitreous body, anterior chamber, and lens cortex and its nucleus had a distinct anechogenic to hypoechogenic pattern. Details of the eyes compartments were better observed by rotating the images in all possible angles and planes using 3D facilities. Anterior and posterior lens capsule and the optic disk were hyperechogenic. The mean ±  SD optical axis was 20.7 ± 0.9 mm in males and 26.3 ± 0.6 mm in females (P<0.05). No significant difference existed between the measurements made in left and right eyes. We found marked advantages in image acquisition for interpretation of all aspects of the ocular structures.     UR - https://ijvr.shirazu.ac.ir/article_531.html L1 - https://ijvr.shirazu.ac.ir/article_531_5bd44f41434b40b3fb18400e7186486c.pdf ER -
