Figure 2

Schematic drawings of three patterns of trabeculotomy cleft. (a, b, c) 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 asterisk indicates the lumen of Schlemm’s canal.
