Abstract

Abstract : Purpose: To report our experience using a Tenon cyst autograft in the management of tube exposure post Ahmed glaucoma valve (AGV) implantation. Methods: This is a retrospective case series. Results: Four patients who underwent tube exposure repair using Tenon cyst autograft were identified in our tertiary care center. The duration between initial AGV implantation and tube exposure ranged between 3 and 36 months with a mean of 16 months (±14.35 mo). All patients were followed postoperatively for a range of 4 to 24 months with a mean of 11.75 months (±9.03 o) and all remain exposure free at last follow-up. Conclusion: The use of a Tenon cyst autograft for the surgical repair of a tube exposure is valuable, as it involves using autologous scar tissue that is available in eyes that have undergone AGV implantation. The patch autograft is technically easy to harvest, and represents a significantly lower cost when compared with other available options.
