Novel B-Scan Technique for Distinguishing a Displaced IOL from a Retinal Mass

In this video, Drs. Soungmin Cho, David Sierpina and colleagues demonstrate a technique to distinguish a posterior dislocated lens from a retinal mass using a B-scan. With the scan probe securely placed, the surgeons show how to move the patient’s head between flexed and extended positions on a representative patient. The B-scan probe is pointed towards the 6 o’clock position on the globe and the patient is advised to look at the 6 o’clock position to maintain the same view during the maneuver. In this demonstration, a posteriorly dislocated lens can be seen sliding down without any attachments to the retina. In addition to A-scan and B-scan patterns, this new technique can be used as another diagnostic tool to assess a posterior segment mass.
