Use of processed pericardium graft to plug patulous old sclerostomy track during glaucoma shunt revision for exposure
Shazly TA; Latina MAOphthalmic Surgery Lasers and Imaging 0; 43: 72-75
The authors demonstrate a reproducible technique using processed pericardium to seal sclerostomy track during glaucoma shunt revision. The suggested method involves placement of a wedge-shaped processed pericardial graft into the old sclerostomy tract following tube explantation. The graft is trimmed and sutured to the sclera. The tube is reinserted into a new sclerostomy and then sutured in place and covered in the usual fashion. This method allowed relatively easy treatment of three patients with patulous sclerostomy with necrotic edges. A successful tube revision and repositioning of the tube using this technique was performed on three patients with exposed tubes. The intraocular pressure was between 8 and 12 mm Hg from postoperative day 1. The authors suggest the use of pericardium plug to adequately seal the old sclerostomy track during glaucoma shunt revision. The plug allows tube repositioning at a new site without the need to suture the friable sclerostomy edges.
