Gross dissection of complex flap in Schlemm's canal and correlative plastic section. (A) Gross dissection of radial wedge of anterior segment showing trabecular meshwork, IW, OW, and Schlemm's canal (SC). Anterior (Ant) and posterior (Post) are noted in the overview of the gross dissection. Inset (black square) shows complex U-shaped flap (CFLP, black arrows) spanning IW and OW with septal columns (SEPC, yellow arrows) and tubule-like structure (T, red arrow) in the posterior portion of Schlemm's canal. (B) Correlative plastic section of SC in same orientation as Figure 5A with transected portions of complex flap (CFLP, black arrows) on IW and OW, SEPC (yellow arrows) on the IW and funnel-shaped attachment of tubule-like structure (T, red arrow) on the OW. Scleral bed of CC in sclera is indicated by green arrow.
