Swept-source microscope-integrated optical coherence tomography four-dimensional (three-dimensional across time) sequence during scleral tunneling. The 23-gauge needle (red arrows) advancing from the surface of the sclera (a), through the sclera into the anterior chamber (b), and to its deepest point in the anterior chamber (c), creating a scleral tunnel for subsequent tube shunt placement

An Ahmed FP7 glaucoma drainage device plate was placed, and SS-MIOCT was used to guide a 23-gauge needle through the sclera 2 mm from the limbus inferotemporally and into the anterior chamber [Fig. 1].
Swept-source microscope-integrated optical coherence tomography three-dimensional volumes (left) with a white box demarcating its corresponding two-dimensional B-scan (right) at the end of tube shunt placement and trabeculectomy surgeries. (a) Tube shunt (red arrows) insertion through the previously established scleral tunnel into the anterior chamber, with proper positioning anterior to the iris and without corneal touch. (b) Scleral flap interface (green arrows), sclerotomy (blue arrow), and iridectomy (yellow asterisk) at the end of a trabeculectomy surgery

SS-MIOCT was used to simultaneously visualize the scleral flap, iridectomy, and sclerotomy [Fig. 2b].
