Figure 7: (a)–(d) Four clinical examples of the complicated and failed CLASS. (a) Complicated CLASS at 1M. Spontaneous TDM perforation and iris incarceration, probably subsequent to the intraoperative microperforation. 1: hyperreflective iris pressing on the area of sclerectomy. 2: remnants of the hyperreflective TDM. 3: collapsed scleral lake. (b) Complicated CLASS at 1M. Postoperative anterior uveitis resulting in peripheral anterior synechia adjacent to the area of sclerectomy. 1: synechia obscuring the TDM. 2: scleral lake. 3: iris stroma. 4: pigmented iris epithelium. (c) Failed CLASS at 3M. The hyporeflective space located posteriorly to the iridocorneal angle suggests inaccurate laser ablation. 1: hyporeflective niche in the area of laser applications. 2: intact iridocorneal angle. 3: microcysts. (d) Failed CLASS at 3M due to early fibrosis. No evidence of intrascleral fluid. 1: no TDM and no scleral lake in area of the presumed sclerectomy. 2: hyporeflective trace of the inner margin of the scleral flap. 3: hyporeflective trace of the outer margin of the scleral flap. 4: conjunctiva.
