Intra-operative and iOCT images in canaloplasty surgery Courtesy of Siebelmann et al. [27]. a Imaging through the prepared Descemet window before donning the suture. The cross shows the scanned area. b The vertical OCT scan showing the suture in the Schlemm’s canal (SC), the trabecular meshwork (TMW), the ciliary body (CB), the iris (I), the anterior chamber (AC) and the cornea (Co). The curvature of the chamber angle (red line) is convex. c Microscope image after closing the suture. The cross shows the scanned area. d The configuration of the chamber angle is now concave, with steepening of the angle between the SC and chamber angle
