New Jersey A-Scans & B-Scans


 

Ophthalmic specialists mainly use two general types of ultrasound diagnostic devices: A-scan and B-scan instruments. The human eye is essentially a sphere of liquid, which makes it difficult to analyze and observe compared to other parts of the body. An A-scan and B-scan ultrasound test is an efficient method for observing the eye and any issues that may be present. Ultrasonic waves bounce back from tissues within and dimensional measurements assist ophthalmologists in delivering an accurate analysis and diagnosis. Ultrasonography imaging is vital for a large range of diagnoses and treatments for eye conditions.

A-Scan in North Jersey

A-scan is short for amplitude scan and is used to measure the length between the cornea and the retina. During an A-scan, a single, one-dimensional beam of sound waves is produced and converted into spikes, which then corresponds with tissue and relates to the height of the echo. The test delivers accurate dimensions that support diagnoses such as a retinal detachment, choroidal melanoma, tumors, and much more.

B-Scan in North Jersey

B-scan refers to the brightness scan, which is performed directly on an anesthetized eye. The B-scan is helpful in emergency rooms and post-surgery exams because of its two-dimensional detailing. The B-scan generates a two-dimensional cross-section of the eye and its orbit. This test is usually used for evaluating posterior segments and orbital pathology, particularly in patients where the ocular media are clouded over and direct viewing is not an option. A B-scan can also be used to diagnose retinal or choroidal detachment, as well as foreign bodies, calcium, and tumors within the eye.

How are A-Scans and B-Scans Implemented?

Before A-scans are performed, your eyes will be numbed with anesthetic eye drops. The doctor will have you sit in a chair with your chin placed on a chin rest to look straight forward. The ultrasound wand will be positioned on the front surface of the eye. During a B-scan, your eyelids will be closed because a gel is applied prior to the probe’s use. The doctor will most likely ask you to move your eyes in several directions. Both scans are quick and deliver fast results because of the minimal preparation that is required.
