Corneal tissue linked to fewer tube shunt exposures than pericardium

Glycerol-preserved corneal tissue delayed exposure of glaucoma drainage shunts significantly longer than pericardium patch grafts, according to a study.“[This study] indicates that [glaucoma drainage implant] coverage with glycerol preserved corneal tissue compared with pericardium may significantly decrease the rate of an exposure event and provide a longer time to initial exposure event. Functional advantages, such as the ability to perform laser suture lysis, and improved cosmesis are further advantages in using corneal tissue,” the study authors wrote.
