Surgical repair of leaking blebs.
To repair a ruptured filtering bleb, we used the conjunctiva alone, or combined with its undissected Tenon's fascia, to cover the sclerostomy site. We used mattress sutures to thread the new flap into a vertical corneal groove anterior to the sclerostomy, creating a firm, nonretracting but still sufficiently "porous" cover that maintained filtration and resisted infection and perforation. Seven of eight cases of ruptured filtering blebs have been successfully repaired in this manner with the maintenance of adequate filtration.
