MMOCT scans of surgical instruments. (A) MMOCT SVP image of an MVR blade. (B) MMOCT B-scan of the MVR blade shows total shadowing under the metallic instrument (arrow). The tip of the instrument is seen as a hyperreflective signal at the leading edge of the shadow (arrowhead). (C) MMOCT SVP of forceps resting on the retinal surface. (D) MMOCT B-scan with forceps resting on retinal surface. Near total shadowing is seen underneath the instrument tip (arrow). Compression of the retinal tissues is seen at the area of the tip.
