Ocular Ultrasound Machine Description
A-scans and B-scans are a form of retinal ultrasound technology that is employed by ophthalmologists to create an accurate and easy-to-use diagnostic tool. Some of the features of A-scans and B-scans include high-frequency sound waves connected to a scanning system, which results in an image being published for both the examiner and the patient to see. A form of eye drops are typically put into the eyes before use, to help the machine give a more accurate reading. The eye drops will numb the patient, and then a transducer device is placed into the eye.
B-scan ultrasounds do not require the use of numbing drops; this device features a brightness pattern, which cross-references the eye with other diagnostic tools. The ophthalmologist will be able to access other instruments to give the most accurate reading of the patient’s eye.
How ocular ultrasound machines work
A-scans are achieved by sending a burst of sound waves into the eye, which bounce off of the eye and revert back to the device as an image. The system is equipped with a scanning screen, where the ophthalmologist can read the information and get precise readings on the eye. This is used to detect any abnormalities or diseases.
A B-scan works slightly differently but is just as accurate. This form of ultrasonography uses a brightness scan on the outside of the closed eyelid, rather than with eye drops like in an A-scan. B-scans are beneficial when it is too difficult to use an A-scan on the patient, due to medical issues or other sensitivities. Both of these scanning types can help diagnose retinal detachment, problems with the lens, and abnormalities with all other structures of the eye as well.
About ocular ultrasound machines
A-scans and B-scans are helpful in determining if there are any problems with the patient’s sclera, choroid, cornea, lens, vitreous, retina, eyelid, and more. If the retina is detached, a slew of problems may occur. Using these two types of scans can more easily diagnose this issue before it becomes a bigger one. This is one of the most popular ways that an ophthalmologist can examine the optical nerve or other areas of the eye in an accurate way.
