Observation of Gonio Structures during Microhook Ab Interno Trabeculotomy Using a Novel Digital Microscope with Integrated Intraoperative Optical Coherence Tomography

Figure 2

Schematic drawings of the three patterns of the trabeculotomy clefts. Based on the flap locations (black and red arrows), the trabeculotomy cleft is classified into an anterior (a), middle (b), or posterior (c) incisional patterns. The black and red arrows indicate posterior- and anterior-based flaps, respectively. The yellow ovals indicate Schlemm’s canal. This figure is a modification of our previous publication in the Journal of Ophthalmology [18].
