Scleral Flap-Everting Suture for Glaucoma-filtering Surgery.

ABSTRACT

PURPOSE: Most filtering surgery failures develop in the early postoperative period. The possibility to apply an everting suture to lift the flap in the postoperative period and reduce the possibility of an early failure is reported. METHODS: Surgical technique description. RESULTS: An everting suture may be applied to the scleral flap in all types of ab externo anterior filtering surgeries. It could allow the surgeon to lift the scleral flap after the removal of the releasable sutures. CONCLUSIONS: The use of an everting suture would eliminate the need to use procedures for lifting the flap that involve puncturing the conjunctiva and may cause hemorrhages and leakage and promote scarring.
