Figure 4. — MMOCT scans of surgical instruments. (A) MMOCT SVP image of a silicone soft-tip. (B) MMOCT B-scan of silicone soft-tip on the retinal surface shows moderate reflectivity and minimal shadowing at tip. Total shadowing from the metallic handle is visible at the left of the image. (C) MMOCT SVP of diamond-dusted membrane scraper. (D) MMOCT B-scan of diamond-dusted membrane scraper on the retinal surface. Minimal shadowing and moderate reflectivity are caused by the posterior silicone-only portion of the tip. Increased shadowing and hyperreflectivity appear in the area of the diamond-dusted tip. (E) MMOCT 3-D reconstruction of the diamond-dusted membrane scraper with hyperreflectivity in the area of the diamond dust. The silicone portion appears to be moderately reflective. Total shadowing is noted posterior to the silicone portion, secondary to the instrument handle.
