Discrimination of Epithelial Face of Conjunctival Autograft in Pterygium Surgery with Fibrin Glue.

A 48-year-old male patient was operated for pterygium. During surgery, the autograft surface was lost because of sponge contact. Presumed epithelial face of the autograft subsequently was attached to the bare sclera with fibrin glue. It was observed that the center of the autograft was freely movable with sponge. This finding showed the inverse implantation of the autograft. Because the glue does not stick to intact corneal or conjunctival epithelium, free movement of the center of the autograft shows that the graft is inversely implanted.
