Bovine pericardium scleral patch graft associated scleritis: Ahmed valve implant for pupillary block glaucoma
Processed bovine pericardium is a lyophilised collagen sheet used as a surgical armamentarium. It renders the material antigenically inert with minimal inflammation [1]. Sclera patch pericardium graft (Tutopatch) is a collagenous membrane derived from solvent preserved, irradiated bovine pericardium [2]...

A patient report of pseudoxanthoma elasticum, angioid streaks and choroidal neovascularisation
