FIGURE 3. Live visualization of a scleral pass as seen with swept-source microscope-integrated optical coherence tomography (SS-MIOCT).

FIGURE 3

SS-MIOCT 3D volume (left) with a white box demarcating its corresponding 2D B-scan (middle) and the standard surgical microscope view (right) showing the needle tip (blue arrow) at the muscle insertion site (green arrow) at the surface interface with the sclera (A), within the thickness (yellow bracket) of the sclera (B), and exiting the sclera (C) with the lowest point of the needle and the suture (D) roughly 40% deep within the thickness of the sclera. The depth of the needle and suture relative to the sclera is much more easily visualized in the 3D volumes and 2D B-scans compared to the standard surgical microscope views (A-D). The suture needle can artifactually appear discontinuous due to different refractive indices of air and tissue. In all SS-MIOCT images, the red scale bar in the 2D B-scan measures 1 mm laterally and the blue scale bar measures 1 mm axially.
