It can provide additional information not readily obtained by direct visualization of ocular tissues, and it is particularly useful in patients with pathology that prevents or obscures ophthalmoscopy. On B-scan, these crystals will show as hyper-reflective foci within the vitreous cavity. If viewed dynamically, they will actually move as the eye moves. When a vitreous detachment occurs, the B-scan will show a reduced volume of the vitreous gel, with a clear delineation between the gel and liquid vitreous.

The B-Scan can recognize a wide breadth of eye conditions and diseases, which include: vitreous bleeding, retinal detachments, intraocular tumors, inflammation, and more. In addition, A-Scan is used to accurately measure the distance between the cornea and retina to identify various eye tumors.

INTRODUCTION
B-scan ultrasonography is an important adjuvant for the clinical assessment of various ocular and orbital diseases.
This presentation is designed to describe the principles, techniques, and indications for echographic examination, as well as to provide a general understanding of echographic characteristics of various ocular pathologies.

B-scan ultrasonography, or B-scan, is a diagnostic test used in optometry and ophthalmology to produce a two-dimensional, cross-sectional view of the eye and the orbit. The ultrasound uses high-frequency sound waves that travel through the eye.

B-scan Ultrasonography, often called just B-scan or Brightness scan, offers two- dimensional cross-sectional view of the eye as well as the orbit. A B-scan is used

2012-02-25 B-scan implies a two-dimensional ultrasonic scanning procedure with two-dimensional display. A B-scan is done for the purpose of evaluating the interior of the eye. Payment will be allowed only for services which are medially reasonable and necessary for the patient’s condition. Summary of Evidence N/A Analysis of Evidence (Rationale for After your B-scan test, there is no downtime. If another test was performed along with the B-scan and the eyes were dilated, you may need a friend to drive you home. But most patients are able to leave our office and return to normal activities.

Situations that prevent normal A B-Scan Ultrasound supplies your eye doctor with an image of the retina when he or she is unable to visualize the retina because of blood or other obstructions. Download scientific diagram | B-Scan Ultrasound of patients right eye showing the classic collar button (mushroom) shape of tumor (white star) without evidence B-scan ultrasonography can often demonstrate the inflammatory changes which occur in orbital fat and extraocular muscles in active eye changes of Graves' B-scan ultrasonography is a form of ocular ultrasound which produces a cross- sectional image of the internal structures of your eye.

It is an important aid in the clinical assessment of the eye. It helps in identifying the different pathologies with the help of ultrasound waves. 8 May 2016 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 Download scientific diagram | B-Scan Ultrasound of patients right eye showing the classic collar button (mushroom) shape of tumor (white star) without evidence Compact Touch STS UBM is a portable ultrasonic biomicroscope (UBM) for imaging the eye from the cornea to the lens. In comparison to optical technologies, B-scan Ultrasonography, often called just B-scan or Brightness scan, offers two- dimensional cross-sectional view of the eye as well as the orbit.

(2001), in our study, the posterior chamber was not usually well visualized with ultrasonography. During her evaluation for cataract extraction, the patient's axial eye length was found to be 17.14 mm OD and 17.04 mm OS. She had normal-sized lenses which were large relative to her small eyes. As one can see in the B-scan ultrasound, her sclera is almost 2.4 mm thick.

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. Eye Ultrasound, A-Scan & B-Scan - Eye Imaging Test second opinion can give you the reassurance and peace of mind that you have the latest, up-to-date diagnosis and best treatment option. In addition, second opinions have undoubtedly saved many lives! Order your consultation from SecondOpinions.com now! It is critical to get a second opinion: B-scan ultrasonography is of value in evaluating patients with media opacities or bullous retinal detachments when a choroidal lesion is suspected but cannot be clearly seen.

The A-scan provides data on the length of the eye, which is a major Santodomingo-Rubido, J.; Mallen, E.A.H.; Gilmartin, B.; and Wolffsohn, J.S. (2002 ).

B-scan ultrasonography is an important adjuvant for the clinical assessment of various ocular and orbital diseases.

However, in many instances, ultrasound is used for diagnostic purposes even though pathology is clinically visible to better differentiate the pathology. Similar to the A-scan, a B-scan (or brightness scan) is used in ophthalmology to produce a two-dimensional cross section of the eye and its orbit.
