Lyophilized Dura Mater Patch Graft in Glaucoma Valve Implantation

ABSTRACT

This study was performed to know effectiveness and safety of cadaveric lyophilized dura mater grafts(Lyodura, B.Braun Melsungen, Germany) to cover glaucoma implant tube. Tewnty-seven eyes of 25 patients who underwent glaucoma implant surgery between April 1996 and September 1997 received a lyophilized dura mater patch graft to cover the subconjunctival portion of the tube and then followed up for clinical signs. The mean follow up visit was 10.3 months (range 5-18 months). All eyes tolerated the lyophilized dura mater grafts well without clinical signs of graft related conjunctival, scleral, of intraocular inflammation. And no conjunctival erosion or melting of the graft was observed. The result of this study suggests that preserved dura mater is maybe a reasonable alternative to eye bank sclera for use in glaucoma implant surgery.
