Among the multiple diagnostic tests and screenings available, ophthalmologists place a high regard on ultrasound. Also known as a sonogram or ultrasonography, this imaging technique utilizes sound waves to create an actual picture of the body’s internal structures, such as organs and tissues. An ultrasound can also be used to show parts of the body in motion, such as blood flowing through blood vessels.
In the case of retinal health and function, retina specialists utilize a diagnostic test known as B-scan ultrasound. This test allows ophthalmologists and technicians to gather valuable information on the status of multiple structures of the eye. These include the lens, retina, vitreous, sclera (the outer white part of the eye), and choroid (a layer of blood vessels and connective tissue supplying the retina’s outer layers with oxygen and blood).
What Are the Benefits of a B-scan Ultrasound?
B-scan ultrasonography (USG) provides a simple, noninvasive method for diagnosing lesions of the eyeball, particularly on its posterior segment. This technique makes it possible to accurately evaluate a wide array of common eye conditions, such as cataracts, vitreous degeneration, retinal detachment, ocular trauma, choroidal melanoma, and retinoblastoma. B-scan ultrasound is most effective when it is impossible to directly visualize intraocular structures or when the view of a patient’s retina is obstructed.
What Does the Ultrasound Process Involve?
Ophthalmic ultrasonography is a non-invasive process. While you may experience a little discomfort, typically, it is a painless procedure. As ultrasound, unlike X-rays, doesn’t use any radiation, you’re spared any health risks or harmful side effects. Typically, the ultrasonography process involves these steps:
- High-frequency sound waves are transmitted from a probe into the affected eye.
- When these sound waves strike the intraocular structures, they’re reflected to the probe.
- These reflected sound waves are converted into an electric signal.
- The signal is then reconstructed as an image on a monitor, which can be used to evaluate the eye and provide diagnostic information.
