Ocular B-mode ultrasonography is an important adjuvant for the clinical evaluation of a variety of eye diseases, especially when ocular media clarity is compromised. Although CT scans and MRI are very useful in many ocular and orbital conditions (as demonstrated by examples in this chapter), they cannot scan in real time, have poorer spatial resolution, and have a limited role in the assessment of the vitreous, retina, and choroid. The dynamic examination, in which the patients are asked to move their eyes from left to right and up to down without opening their eyelids, is essential in detecting of the vitreous and detachment of the posterior vitreous, the retina, and the choroid. Modern multipurpose ultrasound scanners with high-frequency small parts probes are useful for ocular ultrasonography [1–5].
