The Use of Porcine Small Intestinal Submucosa in Ten Cases of Canine Corneal Staphyloma

Abstract

Porcine small intestinal submucosa biomaterial was used to repair corneal staphyloma in 10 dogs. There was no evidence of leakage of aqueous humor and graft rejection following PSIS grafting. Anterior synechia was presented in 25-50% of the corneal area. Granulation tissue vanished within 50 days of the operation. Even though scar formation and anterior synechia were observed at the end of the study, all dogs had vision.
