Figure 1: (a) Slit-lamp photograph at 8-month post-Ahmed valve implantation. The arrow indicates the exposed tube segment. The dashed line outlines the scleral patch graft, (b) Schematic demonstrating layering of scleral and conjunctival grafts during revision surgery. The arrow heads denote sticking of lateral edges of the conjunctival auto-graft to the edges of the reflected conjunctiva and the underlying episcleral surface, (c) Slit-lamp photograph at 4-month post-revision surgery shows well-integrated patch grafts
