Study: Erosions more frequent in corneal than scleral patch grafts
CORONADO, Calif. — Corneal patch grafts eroded faster and more often than scleral patch grafts in patients who underwent glaucoma tube shunt implantation, according to a study presented at the American Glaucoma Society meeting. Azra Idrizovic, DO, and colleagues undertook the study to compare specifically the rates of corneal and scleral patch graft erosion in eyes with glaucoma drainage implants and to examine the risk factors associated with tube erosions.
