Eight months after implantation of AGV, he presented with tube exposure. [Figure 1a]. The lateral edges of the conjunctival graft were stuck to the edges of the conjunctival flap as well as to the episcleral surface beyond the scleral graft using the fibrin sealant [Figure 1b]. The grafts were well integrated and IOP was in the target range at the 4-month post-revision follow-up visit [Figure 1c].
