A B-scan is generally used to evaluate diseases involving the posterior segment (the hind two-third of the eye) and orbit, typically when the ocular media (fluids within the eye) are cloudy and a direct visualization is not possible. They may diagnose eye ailments such as . … Contact B-scan and diagnostic A-scan are most commonly used to evaluate the posterior globe and orbit. Anterior ocular structures can be evaluated with a modified immersion B-scan examination, but are most commonly evaluated with ultrasound biomicroscopy . This chapter describes the proper methods for performing A- and B-scans.

The B-scan is useful to indicate the position of a retinal or vitreous detachment, or of an intraocular foreign body or a tumour, and for the examination of the orbit. The B-scan is especially useful in the examination of the posterior structures of the eye when opacities prevent ophthalmoscopic examination (e.g. cataract, corneal oedema).

In B-scan ultrasonography, an oscillating sound beam is emitted, passing through the eye and imaging a slice of tissue; the echoes of which are represented as a multitude of dots that together form A B-scan is generally used to evaluate diseases involving the posterior segment (the hind two-third of the eye) and orbit, typically when the ocular media (fluids within the eye) are cloudy and a direct visualization is not possible.

B-scan ultrasonography is a form of ocular ultrasound which uses the reflection of sound waves and produces a cross-sectional image of the internal structures of your eye. An ultrasound is used to evaluate the inside of an eye when a condition may limit what the doctor can see by just looking at the eye.

B-scan, or brightness scan, is another method used for ocular assessment via ultrasound. It can be performed directly on the anesthetized eye. In cases of trauma or in children, B-scan can be performed over the eyelid with coupling jelly.

4.7.1 A-scan, B-scan, C-scan and D-scan In the previous part we focused on the physical and technique problems for testing of austenitic welds. The results were mainly presented as A-scan results. For validation of test methods, for a first overview of results of components and for the result analysis a A-scan presentation is still appropriated.
