Autologous tragal perichondrium patch graft for ahmed glaucoma valve tube exposure
Chun YS; Kim KW; Kim JCJournal of Glaucoma 2013; 22: e27-e30
PURPOSE: To describe a novel method of repair for an exposed Ahmed valve tube using tragal perichondrium. METHODS: A 56-year-old man with a severe chemical burn was referred to our clinic for the management of total limbal stem cell deficiency. During the treatment, an Ahmed valve tube was implanted to control refractory glaucoma. Tube exposure occurred 39 months after implantation. A glycerin-preserved donor sclera patch graft was used to cover the exposed lesion. However, 21 months later, the tube became exposed again. Autologous tragal perichondrium was then harvested and used to repair the exposed tube. RESULTS: The exposed tube was closed successfully without recurrence, graft thinning, or graft-related infection or inflammation over a 20-month follow-up period. CONCLUSIONS: Perichondrial patch grafts can be a useful alternative for repair of exposed glaucoma drainage tubes.
