Abstract
|
|
|
Purpose: The objective of this case report was to present tube erosion of Ahmed valve implantation using a synthetic dura substitute (Neuro-Patch®, B. Braun, Boulogne, France).
Case summary: Tube erosion was caused by dissolution of the conjunctiva and partial-thickness scleral tunnel in 5 patients who received Ahmed valve implantation using a synthetic dura substitute for glaucoma treatment 2 to 4 months after the operation. Furthermore, the patients required re-operation for preventing secondary complications such as endophthalmitis.
Conclusions: This case series using a synthetic dura substitute in Ahmed valve implantation demonstrated the risk of tube erosion with scleral tunnel melting and following secondary complications even with a partial-thickness scleral tunnel method.
