Clinical Trial Summary

This was a retrospective, non-comparative study of 100 eyes of 100 consecutive glaucoma patients who had undergone glaucoma drainage device implantation (Baerveldt shunt) during January 2006 to December 2016. Glycerin-preserved, human-donor, corneoscleral tissue was used as a patch graft to cover the tube portion of the GDD over the sclera. The patch graft related complication was comparable to the previous reports using conventional sclera or pericardium.


Description:

This retrospective, non-comparative study was conducted at the Department of Ophthalmology, Faculty of Medicine, Siriraj Hospital, Mahidol University, Bangkok, Thailand. The medical records of consecutive patients who had undergone glaucoma drainage device implantation employing the fornix-based conjunctival flap technique and using a glycerin-preserved, human-donor, corneoscleral graft. The procedures were carried out by, or under the supervision of, one surgeon (NK) between January 2006 and December 2016 were reviewed. The study protocol was approved by the Siriraj Institutional Review Board, Faculty of Medicine, Siriraj Hospital, Mahidol University.

Intervention

Biological:
glaucoma drainage device implantation
Glaucoma drainage device implantation, a 350 mm2 Baerveldt (BG 101-350) GDD (Johnson and Johnson, Santa Ana, CA, USA) was performed using glycerin-preserved, human-donor, corneoscleral tissue ( the remaining from a heterologous, human-donor corneal button, obtained from the International Eye Bank of Thailand, after a clear corneal graft had been used for penetrating keratoplasty.) The tissue had been preserved in glycerin using the sterile technique and kept in a medical refrigerator for no longer than 6 months.
