What is Ophthalmic Ultrasound?

Ophthalmic ultrasound is a diagnostic medical imaging field that utilizes high frequency sound waves to create cross-section B-scan images and Time-Amplitude A-scan images of the globe and orbit. 

 

 

Interpretation of the images is based on knowledge of both the normal and abnormal ocular anatomy, and an understanding of the physical principles of ultrasound. While the technique is relatively easy to learn, significant practice is required to feel comfortable diagnostically. 

 

Over the years, diagnostic ultrasound has been utilized for opaque ocular media situations or evaluation of tumors within the globe and orbit. Recent advances have expanded the use to include interpretation of clear media involving the status and position of the vitreous. 

 

This website is focused predominately on B-scan pattern recognition of ocular and orbital abnormalities in the hope of accelerating the education of those interested in this noninvasive imaging technique.
