Lyophilized Dura Mater Patch Graft in Glaucoma Valve Implantation

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.

The Use of a Preserved Dural(LYODURA(R)) in the Congenital Ptosis Surgery

LYODURA(R) is commercial name of a cleaned, desantigenized, desenzymatised, rendered free of pyogenics, sterilized by gamma rays, and lyophilized dura. Frontalis suspension with LYODURA(R) was performed to a total of 16 patients(21 lids) of congenital ptosis with levator muscle function of 3mm or less in the ptbtic lid. The follow-up period ranged from 2 to 39 weeks with a mean of 19.6 weeks. Postoperative lid levels were judged good, fair, and poor. Good results occurred in 12 of 21 procedures(57.1 %) and fair results in 6 of 21 prqcedures(28.6%). The summation of these two indicates an overall satisfactory result of 18 of 21 cases(85.7%).
