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 B-scan ultrasonogram shows an echogenic subretinal mass with diffuse, ill-defined borders.

It is most useful when direct visualization of intraocular structures is difficult or impossible. 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 (Chapter 4). This chapter describes the proper methods for performing A- and B-scans.

For the first (left) eye, code 76519–LT. Payment is for the technical component of both eyes, and the professional component of the surgical (left) eye. For the second (right) eye, you only can bill for the professional component of the A-scan. This is done by appending modifier 26 to the A-scan code: 76519–26–RT.

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.

Pulmonology (lungs) Figure 2: B-scan ultrasound of the right eye shows an intraocular foreign body (IOFB) with shadowing behind the IOFB on the 7:30 equator posterior (730EP) and 7:30 longitudinal (L730) scans (a, b). There is moderate vitreous debris overlying the IOFB but no distinct track in the vitreous (white arrow).

How Do Ultrasounds Work for the Eye? All ultrasounds are based on how the physics of sound work. Figure 2: B-scan ultrasound of the right eye shows an intraocular foreign body (IOFB) with shadowing behind the IOFB on the 7:30 equator posterior (730EP) and 7:30 longitudinal (L730) scans (a, b).

Ultrasound is helpful for diagnosing retinal detachment, B-scan, or brightness scan, is another method used for ocular assessment via ultrasound.

(2001), in our study, the posterior chamber was not usually well visualized with ultrasonography. 2021-04-15 · B-Scan. 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. Our ophthalmology diagnostic equipment includes: 4Sight, A-Scan Plus Connect, AccuPach VI Pachymeter, & AccuPen & PachPen pachymeters. Call 800-979-2020 for info 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. During the B-scan, the received echoes reflected from the anatomical structures of the eye are converted into a two-dimensional image, thus forming a picture of the “ultrasonic cut”.
